Abstract

The rapid consumption of fossil fuels has caused increasingly climatic issues and energy crisis, which leads to the urgent demand for developing sustainable and clean energies. Electrocatalysts play a key role in the development of electrochemical energy conversion and storage devices. Especially, developing efficient and cost-effective catalysts is important for the large-scale application of these devices. Among various electrocatalyst candidates, earth abundant transition metal compound (TMC)-based electrocatalysts are being widely and rapidly studied owing to their high electrocatalytic performances. This paper reviews the recent and representative advances in efficient TMC-based electrocatalysts (i.e., oxides, sulfides, selenides, phosphides, carbides and nitrides) for energy electrocatalytic reactions, including hydrogen evolution reaction (HER), oxygen evolution reaction (OER) and oxygen reduction reaction (ORR). Different compounds with different applications are summarized and the relative mechanisms are also discussed. The strategies for developing earth-abundant and low-cost TMC-based electrocatalysts are introduced. In the end, the current challenges and future perspectives in the development of TMC research are briefly discussed. This review also provides the latest advance and outlines the frontiers in TMC-based electrocatalysts, which should provide inspirations for the further development of low-cost and high-efficiency catalysts for sustainable clean energy technologies.

Superaerophobic/superhydrophilic surfaces as advanced electrocatalysts for the hydrogen evolution reaction: a comprehensive review

“…Transition metal sulde nanostructures have appeared as favorable non-noble compound candidates for various types of applications. 156,157 There has been much interest in transition metal suldes (TMS) because of their unique structure, abundant active sites, and tunable electronic structure. For example, WS 2 , 158 layered MoS 2 , 159 non-layered Ni 3 S 2 , 160 and Co 3 S 4 .…”

“…Transition metal sulde nanostructures have also appeared as favorable non-noble compound candidates for various type of applications. 156,157 In amorphous MoS 2 compounds, defects and coordinately unsaturated sites are more plentiful than crystalline MoS 2 , resulting in higher HER activities. 226,227 Besides, transition metal-based chalcogenides, particularly Co-based materials, can act as suitable electrocatalysts for the OER.…”

Development of dual-functional catalysis for hydrazine oxidation by an organic p–n bilayer through in situ formation of a silver co-catalyst

“…Various types of photocatalysts and electrocatalysts towards energy applications are extensively investigated in terms of hydrogen evolution, oxygen evolution, CO 2 reduction, oxygen reduction, alcohol oxidation, etc., and some reviews have been published recently. [16][17][18][19][20] We have been studying organic p-n bilayer, including p-type and n-type, semiconductors for application in photoelectrochemical and photocatalytic reactions in the water phase. [21][22][23][24][25][26][27][28][29][30][31][32] Some unique reactions, which had not been induced so far by conventional photocatalysts, were also found to occur.…”

Insight on the active sites of CoNi alloy embedded in N-doped carbon nanotubes for oxygen reduction reaction

“…The metal nanoparticles encapsulated in CNTs not only promote ORR activity but also exhibit good corrosion and oxidation resistance. Therefore, precise control of the growth of CNTs is beneficial to the exposure of active sites and the promotion of ORR activity [35]. With the consideration of these results, this study designed a CoNi-based catalyst for ORR, in which the embedding of N-doped carbon further improved the activity and stability of the catalyst.…”
