“…It is generally implemented via adjusting the pH values and introducing positively or negatively charged functional groups. [ 77 ] When the pH of the solution is below the pH PZC of CeO 2 , its surface hydroxyls can be protonated, and hence the complex anion of the platinum ligand ([PtCl 6 ] 2− ) can be uniformly adsorbed on the positively charged ─O─Ce─OH 2 + surface site of CeO 2 as a single‐atom layer. [ 78 ] Moreover, the surface charge of the support can also be modified through introducing additional functional groups.…”

Carbon dioxide, as an abundant and nontoxic C1 resource, can be extensively applied to produce C1 building blocks via direct and indirect routes. On account of the stable electronic structure and high activation energy of CO2, the most challenging problem of CO2 conversion is the rational design of low‐cost and efficient catalysts with attractive performance. Single‐atom catalysts (SACs) with atomically dispersed metal atoms, strong metal–support interaction, and tunable/unsaturated coordination environment offer a potential choice by achieving maximum atomic utilization and lowering the CO2 activation barrier. Furthermore, the geometric and electronic structure of SACs can be easily regulated by tuning the coordination environment of single atoms, which significantly affects their catalytic performance. In this review, therefore, a comprehensive review of thermocatalytic CO2 conversion to C1 chemicals over SACs is presented. Specifically, the physiochemical and electronic properties, synthesis methods, and characterization technologies are introduced. Thereafter, an overview of catalytic performance and mechanism of SACs is described during thermocatalytic CO2 conversion to C1 chemicals. Finally, the main limitations of current studies on CO2 conversion to C1 chemicals over SACs are summarized, and simultaneouslyperspectives on the future are proposed, in order to provide a guidance for decarbonizing the industries and cycling greenhouse gases.
