In Situ Formation of AgCo Stabilized on Graphitic Carbon Nitride and Concomitant Hydrolysis of Ammonia Borane to Hydrogen

The development of highly-efficient heterogeneous supported catalysts for catalytic hydrolysis of ammonia borane to yield hydrogen is of significant importance considering the versatile usages of hydrogen. Herein, we reported the in situ synthesis of AgCo bimetallic nanoparticles supported on g-C(3)N(4) and concomitant hydrolysis of ammonia borane for hydrogen evolution at room temperature. The as-synthesized Ag(0.1)Co(0.9)/g-C(3)N(4) catalysts displayed the highest turnover frequency (TOF) value of 249.02 mol H(2)·(mol(Ag)·min)(−1) for hydrogen evolution from the hydrolysis of ammonia borane, which was higher than many other reported values. Furthermore, the Ag(0.1)Co(0.9)/g-C(3)N(4) catalyst could be recycled during five consecutive runs. The study proves that Ag(0.1)Co(0.9)/g-C(3)N(4) is a potential catalytic material toward the hydrolysis of ammonia borane for hydrogen production.
