Prof. Song Li (NSRL) cooperated with Prof. Jiang Jun (USTC) and coworkers have successfully employed the highly curved onion-like carbon (OLC) as supports to anchor Pt single-atoms (Pt1/OLC) with a view to mimicking the tip-like sites of catalysts. Their results suggest that a tip-enhanced local electric field at the Pt site on the curved support could largely promote the reaction kinetics for hydrogen evolution [Nature Energy 4(6):512-518(2019)].
