Abstract

MXene, which are known as two-dimensional transition metal carbides have received heavy interest due to their rich elemental diversity and many fascinating physical and chemical properties. Here, Rh (0) nanoparticles deposited MXene catalysts were synthesized by an easy wet-impregnation method for hydrogen production. Rh (0) nanoparticles were conveniently loaded on the surface of MXene (Rh/MXene) were used as an effective nanocatalyst for the hydrogen production from the hydrolysis of ammonia-borane (AB). The morphological and structural characterizations of Rh/MXene catalysts show that Rh nanoparticles were successfully deposited on the surface of MXene substrates. Rh (0) nanoparticles with an average size of 2.55 nm were homogeneously dispersed and deposited on the MXene surface. The Rh/MXene displayed good catalytic performance in the hydrogen production via the hydrolysis of AB, and the turnover frequency value at 25°C was 288.4 min−1, which is comparable to most of the synthesized catalysts. The Rh/MXene catalyst displaying good activity in seven consecutive catalytic cycles can be considered a good nanocatalyst candidate for hydrogen production from the hydrolysis of AB.
