3D Self-assembly of Ultrafine Molybdenum Carbide Confined in N-doped Carbon Nanosheets for Efficient Hydrogen Production

Abstract

Electrochemical water splitting has been intensively pursued as a promising approach to produce clean and sustainable hydrogen fuel. However, the lack of low-cost and high-performance electrocatalysts for hydrogen evolution reaction (HER) hinders the large-scale application. Herein, we have rationally designed and synthesized 3D self-assembly architectures assembled from ultrafine MoC nanoparticles (0D) uniformly embedded within N-doped carbon nanosheets (2D) for HER via a simple protocol. The well-organized 3D nanostructures exhibit very small MoC nanocrystallites (<2 nm), free-stretching conductive carbon nanosheet, high specific surface area and abundant mesopores, which can expose more active sites and facilitate electron/ion transport pathways. Based on the merits of the composition and configuration, the resultant hierarchical 3D self-assembly architectures exhibit remarkable electrocatalytic performance and stability for HER.
