Tuning the local S coordination environment on Ru single atoms to boost the oxygen evolution reaction
Source abstract
Abstract
Engineering the local electronic structure of single atom catalysts (SACs) still remains challenging. In this study, a Ru-NiS2 single atom catalyst with a controlled S coordination environment, where Ru single atoms are implanted on a NiS2 nanoflower consisting of plenty of cross-linked nanosheets, has been developed via a facile atom capture strategy. Using Density Functional Theory (DFT) calculations, it has been revealed that the fine-tuned local S coordination environment can optimize the electronic structure of Ru active sites, and reduce the energy barrier of the rate-determining step for the oxygen evolution reaction (OER), thus boosting the electrocatalytic activity, such as a low overpotential of 269 mV at 10 mA cm-2. This work provides new insights into the rational regulation of the local coordination environment for SACs.
