Abstract
Utilization of nonprecious metals to replace precious metals in the catalytic hydrolysis of hydrogen storage materials causes wide attention. Herein, nonprecious bimetallic nanoparticles loaded on N-doped graphene quantum dots (Co-Ni/N-GQDs) have been synthesized and applied in the hydrolysis of NH3BH3 for the first time. It is demonstrated that Co-Ni/N-GQDs exhibit the obvious bimetallic synergies in the hydrolysis of NH3BH3, and the total turnover frequency (TOF) value reaches 19.94[Formula: see text]mol[Formula: see text]mol[Formula: see text]min[Formula: see text] via the optimized design. This work first explored the catalytic performance for the nonprecious bimetallic nanoparticles loaded on N-GQDs in the hydrolysis of NH3BH3, greatly facilitating the development of both nonprecious metals and N-GQDs in the hydrogen evolution.
