The application discloses a high-activity Pt / GaCe-Al2O3 catalyst and a preparation method and application thereof. Firstly, an Al2O3 carrier doped with Ga and Ce is synthesized through a hydrothermal synthesis method; then, metal Pt is loaded on the synthesized GaCe-Al2O3 carrier through an impregnation method, so as to obtain the Pt / GaCe-Al2O3 catalyst with high dehydrogenation activity. The catalyst has a nanosheet structure and has strong adsorption performance on methylcyclohexane, and under the condition of 300 DEG C and normal pressure, the catalyst has excellent catalytic dehydrogenation activity and stability in a methylcyclohexane dehydrogenation reaction, and can realize an ultrahigh hydrogen release rate.

The invention provides a method for strengthening leaching of valuable metal in a high-nickel lithium battery through mechanochemical coupling transient heat treatment, and particularly provides a method for recycling the valuable metal in a waste high-nickel ternary lithium ion battery. And then transient heat treatment is carried out in a Joule heat high-temperature heat field, so that the lithium component in the high-nickel positive electrode material can be transformed into lithium silicate, and meanwhile, the transition metal oxide is transformed into low-valence or simple substances.
