Study of Catalytic Hydrolysis of Alkaline NaBH4 Solution by Ru/Ni Foam Catalyst

A Ni metal form was used to carry the Ru catalyst to induce the hydrogen gas from the NaBH4 solution. Results show the Ni material was replaced by Ru material. Ru has been coating twice or more to cover all the Ni metal form surface as possible. About 4% of the Ru catalyst plate shows higher hydrogen generation efficiency. Relative to the concentration of NaBH4 solution, the 20 wt.% is consisted with the 4% of Ru catalyst plate. Additional thermal treatment between every coating process, the Ru material can be adhered tightly. Furthermore, adding a layer of plastic film on the Ru catalyst plate can maintain 79% of the generation efficiency after 17 cycles of generation.
