Tracking the in situ generation of hetero-metal–metal bonds in phosphide electrocatalysts for electrocatalytic hydrogen evolution

Abstract

Transition metal phosphides (TMPs) have been intensively pursued in the field of hydrogen evolution reaction (HER) catalysts. The electrocatalytic performance of TMP can be further improved by combining heteroatoms to...

Rational Design of Transition Metal Phosphide‐Based Electrocatalysts for Hydrogen Evolution

“…Exploring the electronic structure changes before and after the catalytic process is beneficial for understanding the local catalytic environment around the active site, which is a prerequisite for developing efficient catalysts. [ 38 ] Numerous studies have proven that the d ‐band center change of metal atoms is an important factor that can affect the adsorption of catalytic intermediates on catalytic surfaces. [ 39 ] Hence, enhancing the catalytic activity of electrocatalysts by modulating their electronic structure is one of the current mainstream strategies.…”

Electronic structure modification of ultrathin MnFeOOH and integration with Ni3S2 as bifunctional electrocatalysts for improved alkaline water splitting

“…, have made significant progress. 6–13 However, these catalysts still generally have poor conductivity, and unsatisfactory catalytic activity and stability. 14 Additionally, most current electrocatalysts are single functional, while bifunctional water electrolysis catalysts are relatively rare.…”

Facile grinding method synthesis of SnS2@HKUST-1 and SnS2@Ni-MOF for electrocatalytic hydrogen evolution

“…A precious-metal-based platinum (Pt) 14,15 catalyst shows excellent catalytic activity and low overpotential for the hydrogen evolution reaction (HER), but its high cost and scarcity seriously hinder its large-scale application. Many transition metal compounds as typical two-dimensional (2D) materials have been studied for HER recently to replace expensive platinum, such as metal sulfides, 16–18 phosphates, 19–21 nitrides, 22–24 carbides, 25–27 and selenides. 28–30 Among these catalysts, sulfides have also attracted a lot of attention resulting from their attractive features, such as modifiable atomic structures and adjustable electronic structures.…”
