Mo-doped Cu0.5Ni0.5Co2O4 nanowires, a strong substitute for noble-metal-based catalysts towards the hydrolysis of ammonia borane for hydrogen production

A novel non-noble metal catalyst towards the hydrolysis of ammonia borane, Mo-doped Cu0.5Ni0.5CO2O4 nanowires, are designed and prepared. For the sample with the optimized doping amount of Mo, the turnover frequency value can reach 195.25 mol(hydrogen) min(-1) mol(cat)(-1). This value is much higher than those of all the other non-noble metal catalysts ever reported in the literature. In addition, there is nearly no activity loss for that catalyst after 6 catalytic cycles. Considering its high performance and low cost, our catalyst can be a strong substitute for noble-metal-based catalysts in AB hydrolysis for hydrogen production.
