▎ 摘　　要

NOVELTY - Graphene loaded polyvinylpyrrolidone (PVP) stabilized nano ruthenium catalyst comprises PVP stabilized nano ruthenium catalyst as active component and carrier comprising graphene in weight ratio of 1-50:1. The PVP stabilized nano ruthenium catalyst and carrier are self-assembled by physical and chemical adsorption methods. USE - Graphene loaded PVP stabilized nano ruthenium catalyst used for production of hydrogen from sodium borohydride and amine-borane (all claimed). ADVANTAGE - The graphene loaded PVP stabilized nano ruthenium catalyst has excellent thermal stability and reusability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of graphene loaded PVP stabilized nano ruthenium catalyst, which involves dispersing PVP stabilized nano ruthenium catalyst and graphene in a water bath, stirring at 60-100 degrees C and 200-600 rpm, leaving still for 1-10 hours, and adsorbing PVP stabilized nano ruthenium catalyst on graphene using chemical or physical adsorption method; and (2) production of hydrogen from sodium borohydride or amine-borane, using the catalyst in a mass ratio of 1-50:1.
