Highly efficient hydrogen production by the RuNi/TiO₂ catalyst using hydrogen storage material

Abstract

The development of efficient heterogeneous catalysts to release hydrogen from hydrogen storage materials is an important challenge for the next hydrogen economy. In this study, a highly dispersed monometallic Ru nanoparticles with a mean diameter of 1.7 nm can be successfully synthesized on TiO₂ supports, which was effective for the hydrogen production from ammonia-borane. The catalytic activity can be significantly enhanced by the alloying with Ni atoms, giving a remarkably high total turnover number (TTO) of approximately 153,000 over 8 h with an excellent turnover number frequency (TOF) of 900 min^-1.
