“…As each of the aforementioned steps needs to be well optimized to achieve highly active and selective photocatalysts, various structural design methods have been developed for promoting the photocatalytic CO 2 reduction performance, as briefly listed in the following: 1) Construction of nano‐/microstructures strategies can control the morphology, size, and shape of materials, which have substantial advantages for enhancing CO 2 photoreduction activity, such as shortening charge migration pathway, [ 126–128 ] increasing reactive catalytic sites, [ 129–133 ] boosting charge separation as well as extending optical transmission length. [ 134–138 ] 2) Doping and formation of solid solution are two main approaches to tailor the crystalline and band structures of photocatalysts.…”

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.

“…Sun et al [ 33 ] reported the preparation of a Z-scheme heterostructure with r-TiO 2 (rutile) modified with gold and g-C 3 N 4 quantum dots to achieve a recyclable and high-efficiency photocatalyst for CO 2 reduction. The photocatalytic activity of (Au, C 3 N 4 )/TiO 2 composite was compared with the C 3 N 4 /TiO 2 , r-TiO 2 , and bulk C 3 N 4 .…”

“…The results demonstrated that the (Au, C 3 N 4 )/TiO 2 photocatalyst has four and five times higher photoactivity in comparison with the bulk g-C 3 N 4 and pristine r-TiO 2 , respectively. This improvement on the photocatalytic performance was attributed to the excellent Z-scheme heterojunction formed in the interface of r-TiO 2 and g-C 3 N 4 [ 33 ].…”

Photocatalytic Reduction of Carbon Dioxide on TiO2 Heterojunction Photocatalysts—A Review

The photocatalytic reduction of carbon dioxide to renewable fuel or other valuable chemicals using solar energy is attracting the interest of researchers because of its great potential to offer a clean fuel alternative and solve global warming problems. Unfortunately, the efficiency of CO2 photocatalytic reduction remains not very high due to the fast recombination of photogenerated electron–hole and small light utilization. Consequently, tremendous efforts have been made to solve these problems, and one possible solution is the use of heterojunction photocatalysts. This review begins with the fundamental aspects of CO2 photocatalytic reduction and the fundamental principles of various heterojunction photocatalysts. In the following part, we discuss using TiO2 heterojunction photocatalysts with other semiconductors, such as C3N4, CeO2, CuO, CdS, MoS2, GaP, CaTiO3 and FeTiO3. Finally, a concise summary and presentation of perspectives in the field of heterojunction photocatalysts are provided. The review covers references in the years 2011–2021.
