Atomically dispersed Cu and Fe on N-doped carbon materials for CO<sub>2</sub>electroreduction: insight into the curvature effect on activity and selectivity
Yue Zhang, Lei Fang, Zexing Cao
Abstract
OH are reduced obviously on the high-curvature Cu@N-CNT. However, the curvature effect is less notable for the single-Fe-atom catalysts. Such discrepancies can be attributed to the d-band center changes of the single Cu and Fe sites and their different dependences on the curvature of carbon-based support materials.
