Rapid and energy-efficient synthesis of a graphene-CuCo hybrid as a high performance catalyst

A general and energy-efficient strategy has been successfully applied for synthesis of a graphene-CuCo nanohybrid, which leads to the highest catalytic activity of Cu-based catalysts up to now toward the dehydrogenation of ammonia borane, and also the excellent activity for electrochemical hydrogen evolution reaction. Moreover, this general method can be easily extended to facile preparation of other graphene-metal systems.
