文摘

Single molecule fluorescence microscopy reveals that copper-in-charcoal鈥攁 high performance click catalyst鈥?has remarkably few catalytic sites, with 90% of the charcoal particles being inactive, and for the catalytic ones the active sites represent a minute fraction (鈭?.003%) of the surface. The intermittent nature of the catalytic events enables subdiffraction resolution and mapping of the catalytic sites.
