Abstract: Abundant and affordable methane is not only high-quality fossil energy, but also the raw material for the synthesis of value-added chemicals. Solar-energy-driven conversion of methane offers a promising approach to directly transform methane to valuable energy sources under mild conditions, but remains as a grand challenge currently. In this Review, recent advancements of photocatalytic conversion of methane are systematically summarized. Insights into the construction of effective semiconductor-based photocatalysts from the perspective of light-absorption units and active centers are proposed and discussed in detail. Moreover, photocatalytic performances of methane conversion over various catalysts are also presented and classified by oxidant systems. Lastly, challenges and future perspectives concerning mechanistic study and practical application of photocatalytic methane oxidation are introduced.

TL;DR: In this paper, the direct and indirect pathways in the design of the photoelectrochemical (PEC) methane conversion system have been discussed, and various catalytic materials and their roles in the reaction pathways are summarized and discussed.
Abstract: Methane has been reported to be directly converted into value-added products through various methods. Among them, photoelectrochemical (PEC) methane conversion is considered an eco-friendly method because it utilizes solar light and is able to control the selectivity to different products by means of application of an external bias. Recently, some PEC methane conversion systems have been reported, but their performance efficiencies are relatively lower than those of other existing thermal, photocatalytic, and electrochemical systems. The detailed mechanism of methane activation is not clear at this stage. In this review, various catalytic materials and their roles in the reaction pathways are summarized and discussed. Furthermore, promising semiconductor materials, co-catalysts, and oxidants have also been proposed. Finally, direct and indirect pathways in the design of the PEC methane conversion system have been discussed.
