Recent progress in bimetallic carbide-based electrocatalysts for water splitting

Abstract

This review provides recent progresses in bimetallic carbides (Bi-TMCs) catalysts for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in water splitting.

The Recent Progresses of Electrodes and Electrolysers for Seawater Electrolysis

“…Until now, various methods have been developed for improving HER performance, including alloy [37][38][39], doping [40,41], selenization [42,43], carbonization [44][45][46][47][48], nitridation [49][50][51][52], etc. The design of cathode electrocatalysts has been introduced in many other reviews [53][54][55]; herein, we only provide some representative work.…”

A Co and Fe bimetallic MOF with enhanced electrocatalytic oxygen evolution performance: exploring the electronic environment modifications upon Fe incorporation

“…5,6 Therefore, researchers focus on developing less expensive catalysts with high activity and enhanced durability. Transition metal (mainly Co, Ni, and Fe)-based catalysts (in the form of nitrides, 7 oxides, 8 carbides, 9 phosphides, 10 and sulphides 11 ) and transition metals integrated on carbon-based materials (like carbon nanotubes, 12 mesoporous carbon nitride, 1 graphene oxides 13 and materials derived from metal–organic frameworks 14 ) have been investigated over the past few decades to achieve efficient and economic water splitting.…”

Interfacial Engineering of MoS2@CoS2 Heterostructure Electrocatalysts for Effective pH-Universal Hydrogen Evolution Reaction

“…Compared with other alternatives, both CoS 2 and MoS 2 have sulfur, which constitutes a higher heterojunction matching degree. Moreover, CoS 2 can improve the electrical conductivity of MoS 2 and the catalytic capacity as a second phase. ,, Generally, HER performance in alkaline and neutral conditions lags that in acidic conditions because of the slow rate at which water molecules dissociate. , Consequently, the advancement of electrode materials for HER demonstrating superior performance across the entire pH range, particularly in alkaline conditions, is pivotal. Furthermore, the implementation of heterogeneous structures offers a viable approach to improve the efficiency of electrocatalytic hydrogen evolution. − By comprehensively considering factors such as material composition, vacancy, structure, and electron transfer, catalysts can be engineered to exhibit more efficient, stable, and controllable performance in reactions like water electrolysis.…”
