Application of ferrous alloy plated electrode on Raney alloy as a platform to alkaline water electrolysis

摘要

Hydrogen is attracting attention as a next generation energy medium due to the growing awareness of global environmental problems. However, it has not been yet developed the technology capable of producing inexpensive and large amounts of hydrogen in accordance with energy demand. This research aimed to produce the cathode electrode with high performance of hydrogen generation catalytic activity in alkaline water electrolysis, using iron alloy plating of Raney alloy as a platform.Focusing on Ni - Zn alloy as a platform, Ni - Zn alloy plating was applied on a stainless steel substrate. Raney catalyst having a high specific surface area was obtained by dissolving only Zn by alkali.....
