摘要
Abstract Molybdenum carbide (Mo 2 C) has been widely applied in energy conversion, electrocatalysis, and other electronic devices, but its nanostructure with certain morphology and porous structure is tough to control. In this work, 1D or 2D porous Mo 2 C nanostructures can be synthesized by carburizing cobalt‐based zeolitic imidazolate framework (ZIF‐67) cladding MoO 3 nanowires or nanosheets hybrid structure under high temperature. The obtained 2D porous Mo 2 C shows a low onset overpotential (η = 25 and 36 mV) and a small Tafel slope (40 and 47 mV dec −1 ) in 0.1 m HClO 4 and 0.1 m KOH as well as great stability. This work highlights a new strategy for the design and synthesis of porous nanostructure Mo 2 C electrocatalysts.
