Doping engineering has been an important approach to boost oxygen evolution reaction (OER) activity, while investigation on the dopant‐induced modification of active sites and reaction kinetics remains incomplete. Herein, taking the cubic CoSe2 as an example, a universal strategy to synergistically achieve active sites and dynamic regulation is developed by incorporating low‐valence Zn. It is revealed...
The introduction of oxygen (O) vacancies has been considered to be an important but challenging way to enhance the activity of electrocatalysts for the oxygen evolution reaction (OER). Substitution by heteroatoms with high electron‐donating ability may be a feasible strategy for triggering O‐vacancies to maintain thermodynamic stability. Herein, density functional theory (DFT) calculations predict...
An outstanding hydrogen evolution electrocatalyst should have a free energy of adsorbed atomic hydrogen of approximately zero, which enables not only a fast proton/electron‐transfer step but also rapid hydrogen release. An economic and industrially viable alternative approach for the optimization of atomic hydrogen binding energy is urgently needed. Herein, guided by density functional theory (DFT)...
Inspired by living systems, the construction of smart devices that can self‐heal in response to structural damage is a promising technology for maintaining the high activity and stability of catalysts during heterocatalytic reactions. Here this study demonstrates an ingenious platform that enabled efficient persulfate (PS) activation for contaminant degradation via integrating a catalyst with photoactuation...
