Synergistic effect of Au and Rh on SrTiO3 in significantly promoting visible-light-driven syngas production from CO2 and H2O†
Abstract
A novel photocatalyst constructed by Rh, Au, and SrTiO3 was developed to realize syngas photosynthesis from low-cost CO2 and H2O feedstock under visible-light irradiation. The synergistic effect of Rh and Au on SrTiO3 contributed to a 22- and 153-fold photoactivity magnification for syngas yield in contrast to Au@SrTiO3 and Rh@SrTiO3 samples, respectively.
