2D transition metal-based phospho-chalcogenides and their applications in photocatalytic and electrocatalytic hydrogen evolution reactions

Abstract

The utilization of hydrogen (H2) as a renewable substitute for fossil fuel can mitigate issues related to energy shortage and associated global warming. The generation of H2 via water splitting...

Revisited Catalytic Hydrogen Evolution Reaction Mechanism of MoS2

“…This is mainly because the electronic structure of the base atoms is modulated using defect engineering to improve its surface conductivity [ 58 ]. In addition, heteroatom doping has important effects on chemical bond formation, adsorption/desorption processes, and the Gibbs free energy of the reaction [ 59 , 60 , 61 , 62 ]. Therefore, the electrocatalytic activity of MoS 2 -based catalysts can be effectively improved according to the electronegativity difference and the type and number of heteroatoms.…”

Mechanically induced self-propagating reactions (MSRs) to instantly prepare binary metal chalcogenides: assessing the influence of particle size, bulk modulus, reagents melting temperature difference and thermodynamic constants on the ignition time

“…6 Their environmental applications 7 including photocatalysis 8 are also very beneficial. The recent focus of scientists is on preparing 2D, 9,10 3D 11 and layer-structured anisotropic MCs 12 to further boost their application potential.…”

Evolution of Mn–Bi2O3 from the Mn-doped Bi3O4Br electro(pre)catalyst during the oxygen evolution reaction

“…In some recent reports, transition metal doping has been shown to enhance the stability and activity. 33,34 Effective doping to the crystal lattice can shift the valence band maxima towards higher potential, which results in reducing the band-gap. 35 The downward shift of the conduction band minima results in an improvement of electrical conductivity or better charge transfer across the catalyst–electrode interface.…”
