“…The possible pathway by which the catalyst reduces CO 2 to CH 4 is shown in Figure 3e. Liu et al 91 synthesized Fe,N-codoped TiO 2 photocatalytic materials (Fe x Ti@C) by injecting selfsacrificing templates (NH 2 -MIL-125(Ti)) in a Fe 3+ solution by calcination. The Fe 0.8 Ti@C catalyst had the highest CH 4 yield of 5.22 μmol h −1 g −1 , which was 7.8 times that of the original TiMOF template and 10.2 times that of the undoped Ti@C catalyst.…”

Carbon dioxide (CO 2 ) is one of the main causes of global warming. Scientists have found that the photocatalytic conversion of CO 2 using visible light can not only reduce CO 2 emissions and thus mitigate the rise of CO 2 concentration in the atmosphere but also produce high-value compounds and fuels, such as CH 4 , CO, HCOOH, and CH 3 OH. TiO 2 -based modified photocatalytic materials have the advantages of high performance and good chemical stability, so they have broad application potential in the field of CO 2 photocatalysis. So far, a lot of research has been done on the way of photocatalytic reaction and the development of materials, but these achievements still have a long way to go for practical engineering applications, and the modification of TiO 2 groups may be one of the ways to promote its engineering application ability. For this reason, this paper reviews the modification measures of defect engineering, photosensitization, heterojunctions, and so on, hoping to be helpful in follow-up research work in the fields of improving the performance of devices, improving the utilization of visible light, reducing the carrier recombination rate, and changing the efficiency of photocatalytic reduction. Among various modification methods, defect engineering and photosensitization have been applied, but heterojunction construction is still the most effective way to improve the reduction rate. Therefore, in this review, we mainly focus on the construction of heterojunctions to improve the reduction rate, especially on the progress of charge transfer mechanism of different heterojunctions. By summarizing the current research status, the future development of heterojunctions is reasonably considered and speculated.

Constructive defect engineering has emerged as a prominent method for enhancing the performance of photocatalysts. The mechanisms of the influence of defect types, concentrations, and distributions on the efficiency, selectivity, and stability of CO2 reduction were revealed for this paper by analyzing the effects of different types of defects (e.g., metallic defects, non-metallic defects, and composite defects) on the performance of photocatalysts. There are three fundamental steps in defect engineering techniques to promote photocatalysis, namely, light absorption, charge transfer and separation, and surface-catalyzed reactions. Defect engineering has demonstrated significant potential in recent studies, particularly in enhancing the light-harvesting, charge separation, and adsorption properties of semiconductor photocatalysts for reducing processes like carbon dioxide reduction. Furthermore, this paper discusses the optimization method used in defect modulation strategy to offer theoretical guidance and an experimental foundation for designing and preparing efficient and stable photocatalysts.

This study provides a comprehensive review of recent advancements in photocatalytic and electrocatalytic carbon dioxide reduction using titanium dioxide catalysts. The basic concepts of light absorption, electron transport, and reduction processes are introduced in this paper, which also delves into the specifics of photocatalytic and electrocatalytic reduction of carbon dioxide. The paper highlights the key applications and benefits of titanium dioxide, including its strong stability, outstanding light absorption capacity, and good electron transport performance, in the photocatalytic and electrocatalytic reduction of carbon dioxide. Furthermore, it examines the impact of various surface modification techniques on catalytic performance, as well as the effects of various titanium dioxide catalyst forms on catalytic activity and selectivity in carbon dioxide reduction. The in‐depth analysis exhibit promising catalytic properties and hold significant potential for future advancements. However, some obstacles still need to be overcome, such as increasing catalytic activity and selectivity while minimizing energy dissipation. Additionally, the paper provides a scientific foundation for accomplishing sustainable carbon conversion, it also calls for additional experimental and theoretical research into the mechanism of action for titanium dioxide catalyst.
