英文摘要	For converting a homogeneous synthetic chemistry reaction to a heterogeneous one, using nanocatalysts, it is essential to investigate the underlying principles and the associated dominant factors of methodologies between inorganic nanoparticles and organic substrates. Here it is reported that novel, hydrothermally synthesized ruthenium (Ru) nanoparticles performed differently in molecular oxygen activation via single electron transfer for cross-dehydrogenative-coupling reactions, following a volcano shaped relationship between their oxidation levels and catalytic activity. Characterizations and a systematic mechanism study indicated that Ru3+ sites contributed to more superoxo- or peroxo-like species being formed from molecular oxygen on Ru nanoparticles with a moderate oxidation level, and the Ru3+ were the highly active species which accelerate this cross-dehydrogenative-coupling reaction via single electron transfer.; National Natural Science Foundation of China [21461162001, 21371011, 21621061, 21229101, 21573005, 21331001]; National Basic Research Program of China [2012CBA01204]; National Key Research and Development Program of China [2016YFB0701100]; Beijing Natural Science Foundation [2162019]; 7th China Postdoctoral Science Foundation [2014T70009]; Postdoctoral Fellowship of Peking-Tsinghua Center for Life Sciences; SCI(E); ARTICLE; 53; 33078-33085; 7
