Hydrogen Production from the Electrooxidation of Ammonia Catalyzed by Raney Nickel, Platinum and Rhodium

摘要

Raney nickel alloys (such as NiAl and NiZn) have been used for years to produce active electrocatalysts for various reactions. The active catalysts are particularly suited for the liberation of hydrogen gas from water [1], but also find use as catalysts for fuel cells [2]. The main advantage of Raney catalysts is that they provide inexpensive high-surface-area substrates which may then be deposited or sputtered with a thin layer of noble metals; catalysts produced in this fashion combine large surface areas with low loadings of noble metals and can be utilized in numerous chemical processes.
