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

ABSTRACT: The development of efficient non-noble metal catalysts for the dehydrogenation of hydrogen (H₂) storage materials is highly desirable to enable the global production and storage of H₂ energy. In this study, Cu _x -(CoO)_1-x /TiO₂ catalysts with a Cu-CoO interface supported on TiO₂ are shown to exhibit high catalytic efficiency for ammonia borane (NH₃BH₃) hydrolysis to generate H₂. The best catalytic activity was observed for a catalyst with a Cu : Co molar ratio of 1 : 1. The highest dehydrogenation turnover frequency (TOF) of 104.0 mol_H2 mol_metal ^-1 min^-1 was observed in 0.2 M NaOH at room temperature, surpassing most of the
