Unveiling the coordination environment of single-atom catalysts for hydrogen peroxide synthesis (2025)
Abstract
A serial of nitrogen coordinated transition metal (cobalt, nickel, and iron) single-atom catalysts (SACs) were prepared through a facile one-pot pyrolytic method at different temperature.The previous results indicate that the activity and selectivity of these SACs differentiate in electrocatalytic hydrogen peroxide (H2O2) generation via oxygen reduction. The metal atoms coorniation environment is hopythesized to be the main causes. This proposal aims to reveal the local coordination environment of SACs by extended X-ray absorption fine structure (EXAFS) measurements. The expected ourcomes will bring new insights for catalyst design and innovative technology for sustaniable and on-site H2O2 synthesis.
