Rh (0) nanoparticles impregnated on two‐dimensional transition metal carbides, MXene , as an effective nanocatalyst for ammonia‐borane hydrolysis

Abstract

Summary 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.

Bird-Nest-Like Multi-Interfacial MXene@SiCNWs@Co/C Hybrids with Enhanced Electromagnetic Wave Absorption

“…In recent years, MXenes, the newly emerged two-dimensional (2D) transition metal carbide and nitride, were first discovered by Gogotsi in 2011. The general formula for MXenes is M n +1 X n T x ( n = 1–3), where M is for the transition metal, X represents the symbol for the element C or N, and T x stands for the surface functional group (−OH, −O and −F) . MXenes have attracted considerable attention in the EMW absorption field owing to their large specific surface area, unique layered structure, and metallic conductivity.…”

Particularly, the abundant surface terminations originating from HF etching can offer additional polarization relaxation and EMW scattering.…”

“…Hydrogen energy is one kind of new energy promoted by various countries at present. Compared with traditional energy, hydrogen energy has the advantages of very high energy value, wide application range, and clean and pollution-free [1][2][3]. Hence, interest in developing suitable hydrogen storage materials has grown rapidly over the past few decades.…”
