Limited fossil fuel resources and increasingly stringent requirement of environmental protection from major greenhouse gases, including carbon dioxide (CO 2 ), which results directly from the burning of fossil fuels, energy savings and greenhouse-effect alleviation have emerged as major global concerns. The development of an "artificial photosynthetic system" (APS) having both the analogous important structural elements and the reaction features of photosynthesis to achieve solar-driven water splitting and CO 2 reduction is highly challenging. Herein, it has been demonstrated that SrTiO 3 -ZnTe can be utilized as an efficient APS for the photoreduction of CO 2 into methane (CH 4 ) under visible-light irradiation ($420 nm). The results indicate that the combination of ZnTe with SrTiO 3 visibly increases the formation of CH 4 by efficiently promoting electron transfer from the conduction band of ZnTe to that of SrTiO 3 under visible-light irradiation, and thereby demonstrate this to be a promising candidate for the photocatalytic conversion of CO 2 into hydrocarbon fuels.
