It is of great importance to understand the origin high oxygen-evolving activity state-of-the-art multimetal oxides/(oxy)hydroxides at atomic level. Herein we report an evident improvement oxygen evolution reaction via incorporating iron and vanadium into nickel hydroxide lattices.

A competitive complexation strategy has been developed to construct a novel electrocatalyst with Zn-Co atomic pairs coordinated on N doped carbon support (Zn/CoN-C). Such architecture offers enhanced binding ability of O2 , significantly elongates the O-O length (from 1.23 Å 1.42 Å), and thus facilitates cleavage bond, showing theoretical overpotential 0.335 V during ORR process. As result, Zn/CoN-C catalyst exhibits outstanding performance in both alkaline acid conditions half-wave...

Electrocatalytic reduction of CO2 to fuels and chemicals is one the most attractive routes for utilization. Current catalysts suffer from low faradaic efficiency a CO2-reduction product at high current density (or reaction rate).

Palladium substitution occurs at site, introducing sulfur vacancy...
