CO-B CATALYST FOR HYDROGEN GENERATING REACTION USING ALKALINE BOROHYDRIDES SOLUTION AND METHOD TO PREPARE THE SAME

摘要

the The present invention provides a catalyst for the hydrogen evolution reaction with the alkali boron hydride solution, the cobalt (Co), and B It provides an oxide or Co and Co-B catalyst for the hydrogen evolution reaction with the alkali boron hydride solution comprising the compound of any one or both of B. In the present invention, a method of manufacturing a catalyst for hydrogen evolution reaction with an alkali boron hydride solution, alkali boron hydride as a reducing agent solution using a Co ^{2 +} to the reduction step (S1); And reduction by drying and firing, and the precipitated catalyst, Co, and Co, and B, or an alkali boron oxide, characterized in that step consisting of (S2) for obtaining a catalyst comprising a compound of any one or both of B hydride It provides a method for producing a Co-B catalyst for hydrogen evolution reaction with the solution. Co-B catalyst for the hydrogen release reaction using a boron hydride alkali solution according to the invention, because compared to the noble metal catalyst is Ru catalyst having a high activity at least 30% to 50%, unlike the commercial Co metal catalyst in a non-noble metal catalyst can replace the expensive noble metal catalyst such as Ru.
