Description

technical field

[0001] The present invention relates to nano-scale porous materials, more specifically, to a nano-porous Fe-P-C material and its preparation method and its application in hydrogen production by electrolysis of water, mainly used as cathode hydrogen production catalyst material in electrolysis water system. Background technique

[0002] In recent years, with the massive exploitation of fossil fuels, the reserves of fossil fuels on the earth are decreasing day by day. The combustion of fossil fuels will produce a large amount of greenhouse gases, leading to the intensification of the global greenhouse effect, and then causing a series of ecological and environmental problems. With the increasingly severe situation, hydrogen energy has received more and more attention in the field of new energy due to its high conversion efficiency and clean and pollution-free. However, the activity and cost of anode catalysts have restricted the large-scale application of dire...
