Anchoring ultrafine RhNi nanoparticles on titanium carbides/manganese oxide as an efficient catalyst for hydrogen generation from hydrous hydrazine

Abstract

The research of a cost effective catalyst with high activity and 100 % selectivity for hydrogen production from hydrous hydrazine under mild conditions is desirable for fuel cell application. In this work, a series of RhNi/MnOx-MXene are prepared by a simple one step wet-chemical method. The synthesized RhNi/MXene catalysts are characterized by XPS, TEM, SEM and ICP-AES. The ultrafine RhNi nanoparticles with size of 2.8 nm are well dispersed on bi-support (MnOx-MXene) surface and advoid the aggregation of RhNi nanoparticles. This unique nanocatalytic system shows an active performance toward N2H4·H2O decomposition at mild condition. The optimized Rh0.7Ni0.3/MnOx-MXene NPs exhibit an excellent catalytic property and the corresponding TOF value can reach to 1101.9 h−1 with 100 % H2 selectivity at mild condition. The remarkable catalytic performance is attributed to the mild affiliation of bi-support to NPs, which not only stabilizes NPs to maintain good dispersion but also leaves sufficient surface active sites to facilitate the catalytic reaction.
