This article provides a timely and comprehensive review focusing on recent advances in the design strategies for photocatalytic CO2 conversion. It emphasizes the importance of key parameters in tailoring the size, morphology, bandgap, and other properties of photocatalysts to improve CO2 conversion efficiency and selectivity. New trends and strategies in structural design to meet the demands for prominent CO2 photoreduction activity are also introduced, offering a comprehensive guideline for designing state-of-the-art photocatalysts with well-defined structures for CO2 conversion.
Photocatalytic CO2 reduction attracts substantial interests for the production of chemical fuels via solar energy conversion, but the activity, stability, and selectivity of products were severely determined by the efficiencies of light harvesting, charge migration, and surface reactions. Structural engineering is a promising tactic to address the aforementioned crucial factors for boosting CO2 photoreduction. Herein, a timely and comprehensive review focusing on the recent advances in photocatalytic CO2 conversion based on the design strategies over nano-/microstructure, crystalline and band structure, surface structure and interface structure is provided, which covers both the thermodynamic and kinetic challenges in CO2 photoreduction process. The key parameters essential for tailoring the size, morphology, porosity, bandgap, surface, or interfacial properties of photocatalysts are emphasized toward the efficient and selective conversion of CO2 into valuable chemicals. New trends and strategies in the structural design to meet the demands for prominent CO2 photoreduction activity are also introduced. It is expected to furnish a comprehensive guideline for inside-and-out design of state-of-the-art photocatalysts with well-defined structures for CO2 conversion.
