Synthesis and Electrocatalytic Applications of Noble Metal Chalcogenides Nanomaterials

“…[5] In recent years, noble metal chalcogenide nanomaterials (NMCNs) have attracted great attention as promising alternatives for electrocatalysis due to their desirable physical and chemical properties. [6] The NMCNs consist of noble metal elements (e. g., Pt, Pd, Rh, Ru, Ir, Os, Au, and Ag) and chalcogens (e. g., S, Se, and Te), as shown in Figure 1. The NMCNs display several welcome advantages in electrochemical reactions: 1) lower cost compared to pure noble metal nanomaterials; 2) alteration of the electronic configuration of noble metals due to interaction with chalcogens, which leads to accelerated kinetics of electrocatalytic reactions and high selectivity of final products; [7] and 3) rich crystal structures, [8] as listed in Table 1, which contribute to enhanced electrocatalytic performances through phase regulation.…”

Engineering defective trimetallic metal–organic framework nanosheets for advanced water oxidation electrocatalysis

“…In particular, hydrogen production via electrochemical water splitting has been generally regarded as one of the most efficient approaches to alleviating the energy crisis and environmental issues. [8][9][10] However, with sluggish kinetics due to the multistep proton-coupled electron transfer, the anode oxygen evolution reaction (OER) of water electrolysis significantly limits the hydrogen production efficiency and rate. 11,12 To improve the OER kinetics and accelerate the reaction rate, introducing appropriate electrocatalysts is a practicable approach.…”

Engineering metallenes for boosting electrocatalytic biomass-oxidation-assisted hydrogen evolution reaction

“…In recent years, 2D materials have received increasing interest due to their compelling properties, such as high specific surface area, highly accessible active sites, and unique structural strain. [16][17][18][19] Among them, metallenes, analogues of graphene, are a class of 2D non-layered metal nanomaterials with thickness less than 5 nm, experiencing a booming development in electrocatalysis. 20,21 Additionally, the precise regulation of electronic structure, surface states, and carrier mobility also enables the metallenes to be competitive candidates for hydrogen production.…”
