Hierarchically porous Ni foam-supported Co and Sn doped Ni3S2nanosheets for oxygen evolution reaction electrocatalysts

“…Due to the global phenomena of climate change, environmental pollution, and energy crises, eco-friendly hydrogen is attracting substantial attention as a next-generation sustainable energy carrier. 1,2 Hydrogen gas has numerous applications in metallurgy, petrochemical refinery, processing foods, and automobiles, and it is advantageous in various ways, including its high energy density (120–140 MJ kg −1 ), the fact that it is the most abundant element, and its environmental friendliness. 3,4 Currently, natural gas reforming methods based on fossil fuels using high-temperature steam account for the majority of hydrogen production.…”

An Efficient Electrocatalyst (PtCo/C) for the Oxygen Reduction Reaction

“…Polymer electrolyte membrane fuel cells (PEMFCs) are typical substances that produce electricity from chemical energy [1][2][3]. Among the components of PEMFCs, the most practical electro catalysts are carbon-supported Pt catalysts, due to their having the highest activity in the oxygen reduction reaction (ORR) [4][5][6][7][8][9][10][11][12][13].…”

Preparation and Performance of a Cu@PtCu/CNF Oxygen Reduction Catalyst Membrane by Electrospinning

“… 2 In this process, the fuel cell catalyst must be an easily dispersible powder material, and it is difficult to achieve precise coordination of electrochemical reaction and mass transfer kinetics due to the “slurry” processing form of the catalytic layer. 3 …”

“…At present, the preparation method of the membrane electrode of the fuel cell is as follows: first, prepare the catalyst slurry; then, directly coat or transfer the slurry onto the proton membrane to obtain the catalyst/proton-exchange membrane module (named catalyst-coated membrane, CCM) and finally attach the gas dispersion layer to CCM to obtain membrane electrode (MEA) . In this process, the fuel cell catalyst must be an easily dispersible powder material, and it is difficult to achieve precise coordination of electrochemical reaction and mass transfer kinetics due to the “slurry” processing form of the catalytic layer …”

“…2 In this process, the fuel cell catalyst must be an easily dispersible powder material, and it is difficult to achieve precise coordination of electrochemical reaction and mass transfer kinetics due to the "slurry" processing form of the catalytic layer. 3 Electrospinning can be used for large-scale preparation of nanostructured materials such as hollow nanotubes and porous nanofibers by adjusting the parameters of the spinning precursor solution, needle type, and spinning environment. 4 Onedimensional carbon materials such as carbon nanofibers (CNFs) and carbon nanotubes (CNTs) have long-range orientation, good electrical conductivity, high temperature resistance, corrosion resistance, and other properties.…”
