Introduction Of Nickel Felt And Nickel Foam: Distinctions And Similarities
Nickel felt is a three-dimensional porous material composed of fibrous nickel particles. It typically exhibits a high surface area and excellent conductivity, making it a material with exceptional adsorption capabilities. The preparation methods for nickel felt include electrochemical deposition, heat treatment, and chemical synthesis. Due to its porous structure and high surface area, nickel felt holds great promise for applications in energy storage, environmental pollution control, and catalytic reactions.
Nickel foam is a porous solid material composed of nickel metal, resembling a sponge-like structure. The preparation of nickel foam usually involves multiple steps of nickel powder treatment, such as foam templating, physical foaming, and chemical foaming methods. Nickel foam possesses a high porosity and large surface area, resulting in excellent catalytic activity and efficient gas adsorption capacity. It finds extensive application potential in catalysts, electrocatalysts, and gas separation.
Nickel felt consists of fibrous nickel particles arranged in a web-like structure, whereas nickel foam exhibits a structure similar to that of a sponge, composed of continuous nickel metal. Nickel felt is prepared through electrochemical deposition, heat treatment, and chemical synthesis, while nickel foam is typically produced using foam templating, physical foaming, or chemical foaming methods involving multiple steps of nickel powder treatment. Nickel felt possesses super adsorption capabilities, making it suitable for energy storage and environmental pollution control. On the other hand, nickel foam demonstrates excellent catalytic activity and efficient gas adsorption capacity, making it applicable in catalysts and gas separation.
Both nickel felt and nickel foam possess a porous structure, providing them with a larger surface area and high porosity. Nickel felt and nickel foam hold extensive application potential in fields such as energy storage, environmental protection, and catalytic reactions. Both materials exhibit good conductivity, making them valuable in electrochemical and electrocatalytic fields.
Production Process of Nickel Foam
Slurry preparation
The most common method for producing nickel foam is the powder metallurgy process. A slurry of nickel powder, binder, and other additives is prepared.
Foam formation
The slurry is poured into a mold and evenly distributed across its surface. A foaming agent is then added, which creates gas bubbles and results in the formation of a porous structure.
Debinding
The binder is removed from the structure by heating, leaving a porous nickel skeleton behind.
Sintering
He nickel skeleton is heated to a high temperature in a controlled atmosphere, causing the nickel particles to fuse and form a continuous, porous structure.
Study on Mechanical Properties of Nickel Foam After Heat Treatment
The nickel foams produced by electroforming of nickel on pu foams, also a heat treatment has applied to evaporate the pu foam, then a uniaxial compression test was applied to measure maximum compressive strength, energy absorption density, efficiency, and normalized stresses. The results indicate that compared with typical open-cell nickel foams and polymer precursors when the electroforming time is 12 h and a heat treatment has applied, the aforementioned properties of the nickel foams had a significant improvement. Improvement of properties will change by increasing the time of electroforming. The heat treatment improved the energy absorption density of open-cell nickel foams for 3.7 times. For the best sample which is a nickel foam with 12 h of electroforming with heat treatment the first maximum compressive strength, energy absorption density, and energy absorption efficiency reach 1.84 (mpa).
The idea of nickel foams refers back to natural porous medias such as wood, bone and other living tissues. These novel materials find their special role in today’s different industries and they are still developing by broad range of experiments. The metallic cellular materials could divide to two categories, open-cell and closed-cell nickel foams. Closed-cell nickel foams has found their industrial applications among, functionally graded materials, foam filled tubes, acoustic dampers, gas silencers and military armors. The closed-cell type of metallic porous materials has shown great specific energy absorptions, energy absorption density, and marvelous dynamic responses to impacts with strengthened structures which has a lot of great studies and are a well-known engineering material.
Among all kinds of porous medias, open cell nickel foams with high porosity are of importance. Ever since the advent of open cell nickel foams prominent properties have been widely investigated and reported in different studies. Three-dimensional open cell structures and considerable specific surface areas of open-cell foams, results in unique features of permeability, high tortuosity, high damping properties, large surface-to-volume ratio, excellent electrically and thermally conductivity; thus, they can be used for thermal management in electronics, battery electrodes, catalyst carriers, exhaust gas recirculation (egr) filters and lightweight structures. Open-cell nickel foams are widely used in electrodes for battery applications. They can be utilized as containers for electrolytes and collectors of electric current. In general, the foams can be subjected to mechanical loading conditions, therefore, high strength is considered as a crucial factor and investigating of the mechanical behavior of nickel foams is considered imperative. The mechanical behavior of cellular structures is governed by their internal architecture21. Various new methods and manufacturing technologies have developed recently for the production of these recyclable materials which depends on the characteristics expected from the porous media. Feasible processes for manufacturing nickel foams reviewed which mainly included infiltration casting, gas entrapment, electro-deposition methods, and powder compact melting.
Physical and Chemical Analysis of Nickel Foam as Alkaline Medium
Ni nickel foam and SS mesh are demonstrated as high-performance and stable electrocatalysts, respectively. For HER, Ni nickel foam exhibited an overpotential of 0.217 V at a current density of 10 mA cm−2 with a Tafel slope of 130 mV dec−1, which were larger than that of the commercial Pt/C catalyst, but smaller than that of the other conductive substrates. Moreover, both Ni nickel foam and SS mesh exhibited high stability during HER and OER, respectively. Furthermore, in the two-electrode system with Ni nickel foam used as the cathode and SS mesh used as the anode, they enable a current density of 10 mA cm−2 at a small cell voltage of 1.74 V. This value is comparable to or exceeding the values of previously reported electrocatalysts for overall water splitting. In addition, NiO on the surface of Ni nickel foam may be the real active species mesh may be the active species for OER. The abundant and commercial availability, long-term stability and low-cost property of nickel nickel foam and stainless steel mesh enable their large-scale practical application in water splitting.
The increasing of energy demands and depleting of fossil fuels are vital challenging issues that call for the urgent discovering of alternative energy resources. Hydrogen is considered as a promising alternative to traditional fossil fuels in the future due to its high energy density and environmental friendliness. Electrochemical water splitting, which consists of two half-reactions, namely oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), is an appealing technology to obtain high-purity hydrogen.The major challenge to accomplish the two half-reactions in electrochemical water splitting is to overcome the intrinsic sluggish kinetics of HER and OER, especially of OER that arise from a complex multistep proton-coupled electron transfer process. Currently, the state-of-the-art electrocatalysts for HER and OER are platinum (Pt) and ruthenium/iridium dioxide (RuO2/IrO2) due to their low overpotential and Tafel slope. However, these precious electrocatalysts suffer from scarcity and high-cost that limit their large-scale practical application to generate high-purity hydrogen resource economically by water splitting. Therefore, it is important to explore earth-abundant and low-cost alternatives.
The studies only employed nickel nickel foam, stainless steel mesh, etc. as conductive substrates, i.e. catalyst support, and the systematic study of the electrocatalytic performance for HER and OER of these commonly used conductive substrates has been rarely reported. Several commonly used conductive substrates, including nickel nickel foam, copper nickel foam, nickel mesh and stainless steel mesh were studied as electrocatalysts for hydrogen evolution reaction, oxygen evolution reaction under alkaline conditions. It was demonstrated that Ni nickel foam and Ni mesh showed better HER activity and the SS mesh showed the best OER performance. Furthermore, in the two-electrode system with the SS mesh used as anode and Ni nickel foam used as cathode, they enable a current density of 10 mA cm−2 at a small cell voltage of 1.74 V, which is comparable to or even better than some reported bifunctional water-splitting catalysts.
