摘要：

In this work, series bimetallic PtRu/TiO2(P1Rx/TiO2) were prepared by one-pot glycol reduction method. The synergetic effect between Pt and Ru was discussed. Compared to mono-metal-decorated Pt/TiO2, P1Rx/TiO2 showed enhanced electron separation ability due to the electron-withdraw ability of Ru. Also, enhanced photocatalytic CH4 production was realized over P1R1/TiO2 (yield rate of 7.82 mu mol/g.h(-1) and selectivity of 58.50%). Ru sites were proven to be effective CO2 hydrogenation centers that could further convert byproduct H-2 into CH4 during CO2 photoreduction.
