Bottom-up Synthesis of Porous NiMo Alloy for Hydrogen Evolution Reaction

Bottom-up Synthesis of Porous NiMo Alloy for Hydrogen Evolution Reaction

Bottom-up synthesis of porous NiMo alloy reduced by NiMoO4 nanofibers was systematically investigated to fabricate non-noble metal porous electrodes for hydrogen production. The different annealing temperatures of NiMoO4 nanofibers under hydrogen atmosphere reveal that the 950 °C annealing temperatu...
