摘要The combination of noble metal and oxide support is a good approach to reduce the cost of noble metal catalyst and improve the stability of nanocatalyst in chemical reactions. Here, noble metal/zinc oxide composites, including Pd/ZnO and Pt/ZnO, have been facilely prepared through the general one-pot hydrothermal method. Importantly, the morphology of composites can be tuned from tube, flower, and star to skin needling-like shapes by easily adjusting the alkalinity of the reaction solution. By investigating the growth mechanism and influencing factors of the morphology of noble metal/zinc oxide composites, the differences of the morphology of composites can be ascribed to various growing units and directions of ZnO crystal under different alkalinities. Among them, Pd/ZnO composites exhibited both higher catalytic activity and excellent stability in the Suzuki coupling, reaction between iodobenzene and phenylboronic acid and the reduction of 4-nitrophenol to 4-aminophenol by sodium borohydride. Such supported composites will potentially be used as green and sustainable catalysts for many chemical reactions.; The combination of noble metal and oxide support is a good approach to reduce the cost of noble metal catalyst and improve the stability of nanocatalyst in chemical reactions.
