Distinctive MoS₂-MoP nanosheet structures anchored on N-doped porous carbon support as a catalyst to enhance the electrochemical hydrogen production

Abstract

The construction of excellent performance electrocatalysts for hydrogen evolution reaction (HER) with low-cost and economical strategy was still struggling with an enormous challenge in electrochemical water splitting. In this paper,...

One-Step Synthesis and Operando Electrochemical Impedance Spectroscopic Characterization of Heterostructured MoP–Mo2N Electrocatalysts for Stable Hydrogen Evolution Reaction

“…30,31 The heterojunction catalyst exhibited significant catalytic activity with remarkable stability for HER that could be derived from distinctive nanosheet morphology increasing active catalytic sites, the synergistic effect of MoP and MoS 2 phases, and efficient electron movements. 31 Loomba et al designed synthesizing porous nitrogen-doped NiMo 3 P (N-NiMo 3 P) microsheets. 32 They found that inducing nitrogen increased the corrosion resistance, and the higher electronegativity of nitrogen in metal−nitrogen bonds yielded greater stability of the active sites.…”

“…Recently, MoP-based heterojunction catalysts were developed for efficient HER performance. Yang et al successfully synthesized the heterostructure catalyst of MoS 2 –MoP anchored on the N-doped porous carbon (NC) substrate. , The heterojunction catalyst exhibited significant catalytic activity with remarkable stability for HER that could be derived from distinctive nanosheet morphology increasing active catalytic sites, the synergistic effect of MoP and MoS 2 phases, and efficient electron movements .

Cobalt incorporation and MoS2–NiS2 heterostructure synergistic for improving full water electrolysis efficiency

“…Electrocatalytic water electrolysis is a bright technical scheme used to generate clean and renewable hydrogen fuel. 1,2 Water electrolysis was separated into both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Pt, RuO 2 or IrO 2 contained in electrocatalysts is usually used to promote water electrolysis by reducing the inherent activation barrier.…”
