Abstract
molecular dynamics, density functional theory and experimental verification. Compared with weak electrostatic bonds, the rapid surface evolution of electrocatalysts can be revealed due to the strong chemical grafting between the MQDs and LDHs. The reconstituted Ni-Co LDH@MQD electrocatalysts undergo an unconventional bifunctional mechanism to lower the barriers of the rate-limiting step of the OER. This work provides a research strategy for transition metal catalysts for efficient catalysis by designing surface reconfiguration.
