c–obond activation is a highly efficient,fundamental strategy in the depolymerization and hydrodeoxygenation of chemicals with oxygen-containing functional groups such as oil,coal,and *** efficient catalysts for c–oactivation with ultralow-loading noble and non-noble metals is highly desirable for the improvement of metal atomic ***,bimetallic catalysts with atomically dispersed Pt and Nio clusters on different supports were fabricated,and the prepared Pt^(δ+)-Nio/Nb_(2)o_(5)and Pt^(δ+)-Nio/Tio_(2)showed outstanding activity for the hydrogenolysis of benzyl phenyl ether with>99%yield of phenol and toluene due to the excellent cooperation of atomically dispersed Pt and Nio *** synergy mechanism between Pt and Ni and their respective roles in the bimetallic catalyst for c–o hydrogenolysis were clearly *** findings deepen our understanding of the synergy of the two active components and are expected to provide new design concepts for the development of multicomponents catalysts.
