Synergistic interface between metal Cu nanoparticles and CoO for highly efficient hydrogen production from ammonia borane

TiO 2 -supported Cu x –(CoO) 1− x /TiO 2 catalysts exhibit high catalytic efficiency for NH 3 BH 3 hydrolysis. The Cu–CoO interface provides bifunctional synergistic sites for H 2 generation, with activation and adsorption of NH 3 BH 3 and H 2 O on the surface of Cu and CoO, respectively.
