“…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.

“…The existence of electrons and holes in the CB of the g-C 3 N 4 and VB of Nb-TiO 2 , respectively, makes the Nb-TiO 2 /g-C 3 N 4 system a potential candidate for reducing of CO 2 into CH 4 and CO and HCOOH. Guo and coworkers were thermally deposited g-C 3 N 4 onto the porous ZnO nanosheets by two-step calcination and demonstrated that the ZnO porous nanosheets @ g-C 3 N 4 -0.4 showed the highest CO 2 conversion efficiency [433]. Not only this composite suppressed the photoinduced electron recombination and facilitated the carrier transfer, but also the CO 2 chemosorption increased in this composite since the increasing defect vacancies formed on the porous ZnO nanosheets.…”

g-C3N4 has drawn lots of attention due to its photocatalytic activity, low-cost and facile synthesis, and interesting layered structure. However, to improve some of the properties of g-C3N4, such as photochemical stability, electrical band structure, and to decrease charge recombination rate, and towards effective light-harvesting, g-C3N4–metal oxide-based heterojunctions have been introduced. In this review, we initially discussed the preparation, modification, and physical properties of the g-C3N4 and then, we discussed the combination of g-C3N4 with various metal oxides such as TiO2, ZnO, FeO, Fe2O3, Fe3O4, WO3, SnO, SnO2, etc. We summarized some of their characteristic properties of these heterojunctions, their optical features, photocatalytic performance, and electrical band edge positions. This review covers recent advances, including applications in water splitting, CO2 reduction, and photodegradation of organic pollutants, sensors, bacterial disinfection, and supercapacitors. We show that metal oxides can improve the efficiency of the bare g-C3N4 to make the composites suitable for a wide range of applications. Finally, this review provides some perspectives, limitations, and challenges in investigation of g-C3N4–metal-oxide-based heterojunctions.
