One-step synthesis of amorphous transition metal sulfides as bifunctional electrocatalysts for the hydrogen evolution reaction and oxygen evolution reaction

Abstract

The search for efficient and stable bifunctional electrocatalysts for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) is very important for the practical application of water splitting under...

An efficient Ni3S2–Ni electrode constructed by a one-step powder metallurgy approach for the hydrogen evolution reaction

“…However, as a noble metal catalyst, Pt is expensive and scarce, which limits its wide application, and thus it is urgent to find a cheap and renewable non-noble metal catalyst to replace Pt. 13–15 In the last few decades, transition metals, alloys 16,17 and transition metal compounds, such as transition metal borides, 18 carbides, 19,20 selenides, 21,22 nitrides, 23–25 oxides, 26 phosphides, 27,28 and sulfides, 29,30 have been widely reported for the HER due to their unique electronic properties. For example, Cao et al 25 synthesized Mo(N)/Co nanosheets via hydrothermal synthesis, excessive corrosion, heat treatment and nitridation.…”

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][17][18] phosphates, [19][20][21] nitrides, [22][23][24] carbides, [25][26][27] and selenides. [28][29][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.…”

Applications of Rare Earth Promoted Transition Metal Sulfides in Electrocatalysis†

“…At present, there are some reviews on electrocatalysis related to transition metals and their sulfides. [ 9‐14 ] However, the work of introducing rare earths into electrocatalytic reactions to promote transition metal sulfides has not been well summarized. Therefore, it is urgent to design and synthesize new rare earth promoted transition metal sulfides and adjust their performance to meet high‐efficiency and stable electrocatalytic performance.…”
