Spatiotemporal imaging of electrocatalytic activity on single 2D gold nanoplates <i>via</i> electrogenerated chemiluminescence microscopy

Abstract

imaging, which elucidates the time-varying changes in the spatial distribution of electrocatalytic activity on individual nanoplates, indicating that the corners and edges with more defect sites exhibit higher reactivity, but lower stability than the flat facet. We believe that real-time and high-throughput ECL microscopy may lead to more comprehensive understanding of reactivity patterns of single nanocatalysts.
