Guanosine-assisted synthesis of a core–shell Mo₂N/Mo₂C/C structure for enhanced hydrogen evolution reaction

Abstract

Coupling molybdenum-based materials with carbon is an effective strategy to improve the hydrogen evolution reaction (HER) performance. However, achieving the desired surface-active sites by regulating the catalyst's morphology presents a...

A Highly Active Porous Mo2C-Mo2N Heterostructure on Carbon Nanowalls/Diamond for a High-Current Hydrogen Evolution Reaction

“…It is verified that the construction of a heterostructure is a viable and efficient way to improve HER performance. Nevertheless, most studies focus on the HER characteristics at low current density, e.g., 10 and 100 mA/cm 2 , which falls short of addressing the practical application at high current operation [23,24]. In addition, in the case of above nanoparticle-type electrocatalysts, binders were needed to immobilize the particles onto a current collector, which possesses, however, several drawbacks, such as restricting exposure of the active sites, impeding mass transport, and obstructing electron transfer that reduce the overall HER performance [25,26].…”
