Problems solved by technology

[0005] Chinese patent application 201010134982.5 reported a Ru / C catalyst using a porous carbon material as a carrier. This catalyst has a large surface area, high activity, and long life. However, the precious metal Ru has limited reserves and is expensive, so it is not widely used in practice.
However, this unsupported catalyst is prone to agglomeration, resulting in a sharp drop in catalytic activity and poor reusability.
[0007] At present, sodium borohydride hydrolysis catalysts have defects such as high price or low catalytic activity, poor performance, poor catalyst reuse and regeneration performance, etc.
