The single Pt1 and Au1 atoms stabilized by lattice oxygen on ZnO{10-10} surface for methanol steam reforming is reported here by theoretical and experimental study. Extensive density functional theory calculations reveal that the catalysis of the single precious metal atoms together with coordinated lattice oxygen stems from its stronger binding towards the intermediates, lower reaction barriers, changing on the reaction pathway. The measured turn-over-frequency of single Pt1 sites was more than 1000 times higher than the pristine ZnO. The results provide valuable insights for the catalysis of the atomic dispersed precious metals on oxide supports.
