Highly dispersed Pt species, typically subnanometric clusters and single-atoms, feature catalysis that differed significantly from that of the faceted nanoparticles. However, the catalytic chemistry of these size-specified Pt entities is still a subject of debate. Here, we report that metallic Pt cl...
