A 2D/2D heterojunction of ultrathin Pd nanosheet/MXene towards highly efficient methanol oxidation reaction: the significance of 2D material nanoarchitectonics

Chemical Science, Journal Year: 2023, Volume and Issue: 14(36), P. 9854 - 9862

Published: Jan. 1, 2023

Two-dimensional (2D) Pd nanosheet-based catalysts have recently garnered widespread attention due to their high atom utilization efficiency. However, catalytic ability and structural stability still require significant enhancement before they can be widely applied. In this study, we presented the rational design controllable fabrication of a novel 2D/2D heterojunction, which consists ultrathin nanosheets (NSs) grown on Ti3C2Tx MXene surface (Pd NSs/MXene). This heterostructure was achieved through robust convenient stereo-assembly strategy. The newly developed NSs/MXene heterojunction not only provides numerous exposed active atoms with an optimized electronic structure but also enables intimate Pd/MXene interfacial interaction, ensuring stable hybrid configuration. Consequently, resulting exhibits exceptional methanol oxidation properties. It possesses large electrochemically area, mass specific activities, long operating life, are significantly superior those traditional nanoparticle/carbon nanosheet/carbon catalysts. Theoretical simulations further reveal strong interactions between nanosheet MXene, dramatically enhance adsorption energy component simultaneously lower its d-band center. As result, is less susceptible CO poisoning. work introduces new based noble metallic materials holds significance for development other heterojunctions, particularly within realm 2D material nanoarchitectonics.
