Dual-carrier modified ternary alloy nano-cavity catalyst as well as preparation method and application thereof

The invention discloses a double-carrier modified ternary alloy nano-cavity catalyst and a preparation method and application thereof, the catalyst with a unique nano-cavity multilevel structure can be prepared by the method, more active sites are exposed on the surface, the contact probability of borohydride radicals and the surface of the catalyst is increased, and the catalytic activity of the catalyst is improved. The adsorption and desorption of hydrogen are facilitated, the hydrogen desorption kinetics is increased, and the hydrolysis hydrogen production rate is increased; the preparation method has the advantages of being simple in preparation process, easy to operate, low in preparation cost and the like, is suitable for large-scale preparation, is simple in subsequent treatment process, is beneficial to separation and contact of the sodium borohydride fuel liquid and the catalyst, and is easy to produce at any time when being used. 本发明公开了一种双载体修饰三元合金纳米腔催化剂及其制备方法与应用，通过本发明方法可制备获得具有独特的纳米腔多级结构的催化剂，使得更多的活性
