Catalyst overcoating engineering towards high-performance electrocatalysis

Abstract

The recent advances of applying surface overcoating engineering for designing high-performance electrocatalysts for application in sustainable energy-based electrocatalysis are reviewed.

Protocol to modify the surface of nano-Cu2O using facet controlling and MOF shell coating

“…Materials with specific nanoscopic or microscopic morphologies have extensive perspective of application, especially in heterogeneous catalysis, optical devices, and batteries ( Lai et al., 2019 ; Liu et al., 2022 ; Diehl et al., 2022 ; Joshi et al., 2021 ). As an outstanding semiconductor material, Cu 2 O has been widely investigated in photo or electrocatalysis, due to its relatively low cost, abundance of Cu on earth and promising selectivity of specific product, whose surface morphology will profoundly influence its catalytic performance ( Ma et al., 2021 ; Wu et al., 2019 ; Liu et al., 2021 ; Gao et al., 2020 ).…”

Electrochemical water oxidation catalyzed by a mononuclear cobalt complex of a pentadentate ligand: the critical effect of the borate anion

“…[1][2][3][4][5] In the past few decades, massive efforts have been paid to achieving efficient hydrogen production by electrochemical water splitting. [6][7][8][9][10][11][12][13][14][15] However, as a half reaction of water splitting, water oxidation restricts the efficiency of overall water splitting due to its high activation energy. Therefore, water oxidation catalysts (WOCs) with good activity and long-term stability are highly desirable.…”

Rationalization of the sub-surface segregation in nanoalloys of weakly miscible metals

“…Since about two decades nanoalloys have been widely investigated, both experimentally and theoretically, in the perspective of many technological applications [1][2][3][4] among which nanomedecine and catalysis have given rise to a very abundant literature because of nowadays essential societal reasons. [5][6][7][8][9][10] The mixing of at least two metallic species in one nanoparticle offers the possibility of tuning its properties and possibly to improve the known properties of the pure constituents. A major concern with nanoalloys is their stability after synthesis related to their thermodynamically stable structure towards which the system could evolve over time while possibly losing the targeted properties.…”
