Magnetic RuCo nanoparticles supported on two-dimensional titanium carbide as highly active catalysts for the hydrolysis of ammonia borane

RuCo nanoparticles were in-situ synthesized and immobilized on the surface of graphene-like titanium carbide (Ti 3 C 2 X 2 ). RuCo nanoparticles were found to be well dispersed on Ti 3 C 2 X 2 surface. The catalytic property of RuCo/Ti 3 C 2 X 2 for hydrogen generation from the hydrolysis of ammonia borane at room temperature was investigated. Ru 1 Co 9 /Ti 3 C 2 X 2 showed the highest turnover frequency of 896 mol H 2 ·(mol Ru·min) −1 because of the synergetic effect between Ru and Co nanoparticles. The catalyst can also be easily separated from the reaction system by using a magnet and can be recycled at least four times, thereby showing potential practical applications.
