英文摘要	The cleavage of c-o linkages of aryl ethers into aromatic platform compounds is a challenging reaction but of great importance for the sustainable future. herein, we reported the efficient h-2-assisted c-o bond cleavage of diphenyl ether (dpe) in aqueous phase over ultrasmall rupd bimetallic nanoparticles (nps) supported on amine-rich silica hollow nanospheres (nh2-sio2). rupds/nh2 sio2 with tof of 172 h(-1) and c-o cleavage selectivity of 99% outperformed the corresponding monometallic counterparts and is among the most active solid catalysts for c-o bond cleavage of dpe. the control experiments and characterization results showed that the effective isolation of ru sites and optimized h-2 dissociation ability mainly contributed to the enhanced catalytic performance of rupd bimetallic nps, in which ru and pd worked cooperatively with ru sites for dpe activation and pd sites for h-2 dissociation. the alloying of two or multiple metal atoms provides an efficient approach for designing high-performance catalysts for chemical transformations.
