Embodiment 1
[0029] Put the metal powder in a vacuum ball mill, add a small amount of metal chloride aqueous solution and additives, and carry out wet ball milling under the protection of hydrogen. The oxide layer or the hydroxide formed by the reaction is peeled off by the metal powder under the action of ball milling, exposing more Multiple active sites, thereby increasing the yield and reaction rate of hydrogen production.
[0030] The metal powder is aluminum powder. The metal chloride is aluminum chloride. The mass concentration of the metal chloride aqueous solution is 30%. The additive is copper. The vacuum degree of the vacuum ball mill is 0.001Pa. The balls of the vacuum ball mill are zirconium balls, and the ball-to-material ratio is 2:1. The rotating speed of ball milling is 250r / min, and the ball milling time is 90min. In the wet ball milling system, there are 72 parts by weight of metal powder, 20 parts by weight of metal chloride aqueous solution, and 8 parts by weight o...
