Recent Advances in Engineered Ru‐Based Electrocatalysts for the Hydrogen/Oxygen Conversion Reactions

“…Thus, the electron density and d‐band center of the active metal site are carefully altered, which facilitates the adsorption of reactants and intermediates. [ 62,63 ]…”

“…Thus, the electron density and dband center of the active metal site are carefully altered, which facilitates the adsorption of reac tants and intermediates. [62,63] The incorporation of O atoms to Ru crystal structure forming RuO 2 has been considered promising OER catalysts due to the relatively higher activity. Ru is coordinated with five O atoms in RuO 2 (110) facet to form an unsaturated site (Ru cus ), which is the adsorption site for water molecules in the acidic OER pro cess to preferentially generate *OOH through successive depro tonation.…”

Understanding the water molecule effect in metal-free B-based electrocatalysts for electrochemical CO2 reduction

“…In light of the above analysis, the development of twodimensional materials doped with non-metal atoms has been carried out to reduce costs and improve intrinsic catalytic activity via the control of geometric and electronic structures. [43][44][45] The rational design of carbon-supported Bi nanoparticle catalysts has been used to demonstrate highly selective and efficient conversion of CO 2 to formate. 46 Based on the results, the material bismuthene can be applied as an electrocatalyst for CO 2 RR.…”

Curvature effects on the bifunctional oxygen catalytic performance of single atom metal–N–C

“…However, their prohibitive cost and scarcity prevent their widespread usage. [5][6][7] As a result, it is critical to develop high-performance and inexpensive non-noble metal electrocatalysts. Non-noble metal single-atom catalysts (SACs) with their metal-nitrogen-carbon coordination, namely, the so-called MN 4 structure have attracted the attention of many researchers in recent years, due to their full metal utilization, superior catalytic activity, and affordable price.…”
