要旨

Electrochemical CO2 reduction to a valuable product is a sustainable and economical method towards carbon neutralization. Among the different products of the electrochemical CO2 reduction reaction (CO2RR), methane is an excellent energy carrier with a high combustion heat. However, for higher methane product selectivity it is crucial to avoid C–C coupling that leads to multi-carbon products. Thus, single-site catalysts (SSCs) with a single active site are ideal candidates. This review summarizes and discusses the current research progress and future application prospects of electrochemical CO2 methanation on SSCs. The CO2 methanation mechanism and primary activity descriptors are discussed in detail with an extensive overview of the coordination structure and design of SSCs, as well as their several in situ characterization methods for tracking the structural changes in SSCs. This review provides insights into the further exploitation of SSCs for selective CO2 methanation that inspires the rational design of SSCs in electrochemical CO2 methanation research.

Energy & Environmental Science is an international journal dedicated to publishing exceptionally important and high quality, agenda-setting research tackling the key global and societal challenges of ensuring the provision of energy and protecting our environment for the future. The scope is intentionally broad and the journal recognises the complexity of issues and challenges relating to energy conversion and storage, alternative fuel technologies and environmental science. For work to be published it must be linked to the energy-environment nexus and be of significant general interest to our community-spanning readership. All scales of studies and analysis, from impactful fundamental advances, to interdisciplinary research across the (bio)chemical, (bio/geo)physical sciences and chemical engineering disciplines are welcomed. Topics include, but are not limited to, the following: Solar energy conversion and photovoltaics Solar fuels and artificial photosynthesis Fuel cells Hydrogen storage and (bio) hydrogen production Materials for energy systems Capture, storage and fate of CO2, including chemicals and fuels from CO2 Catalysis for a variety of feedstocks (for example, oil, gas, coal, biomass and synthesis gas) Biofuels and biorefineries Materials in extreme environments Environmental impacts of energy technologies Global atmospheric chemistry and climate change as related to energy systems Water-energy nexus Energy systems and networks Globally applicable principles of energy policy and techno-economics
