Problems solved by technology
[0007] At present, sodium borohydride (NaBH 4 ) The catalysts used for hydrogen production by hydrolysis are all disposable, and their disadvantages are: 1. The catalysts cannot be reused after they are used up, which makes the cost of hydrogen production high
2. The preparation process is more harmful, and it is easy to cause the harm of alkaline stimulation, which seriously affects the human respiratory system and skin; 3. The manufacturing conditions are relatively high, and it is very inconvenient to operate
4. When using existing catalysts to produce hydrogen, due to the catalysts used, the general conditions of the production process are relatively high, the production equipment is relatively complicated, and the cost is also high
