“…Several types of reactors can be employed, including top‐down illumination photoreactor, inner/immersed illumination photoreactor, spiral suspension photoreactor, slurry photoreactor, and panel photoreactor [24] . When selecting a reactor for the photocatalytic CO 2 reduction to methane, important considerations include the phase involved (e. g. single‐phase or multiphase solid‐liquid, gas‐solid, or gas‐liquid‐solid), the operating system (e. g. batch, semi‐batch or continuous), the geometric configuration (dimensions and shape), and the light irradiation setup [96–98] …”

Addressing the escalating concerns over increasing carbon dioxide (CO2) emissions and their detrimental effect on the environment has become global attention. One promising alternative to tackle this issue involves utilizing photocatalytic technology to convert CO2 into more valuable chemicals, with methane (CH4) being a notable targeted product. This article presents a comprehensive review of the exploration of TiO2‐based photocatalysts by researchers worldwide for such applications. The initial discussion revolves around fundamental aspects, including the basic principles, thermodynamics, kinetics, and reaction mechanisms involved in the process. Additionally, to enhance the efficiency of these aspects, support from other factors is necessary, including the physicochemical properties of the photocatalyst through various catalyst synthesis methods (such as sol‐gel, precipitation, hydrothermal, and solvothermal) as well as employing catalyst modification techniques (such as doping, heterojunction, and surface modifications). Furthermore, the review delves into an examination of parameters that influence the photocatalytic CO2 reduction to methane process, as they directly impact the yield and selectivity of the desired product. Ultimately, the existing challenges and potential research opportunities that could provide comprehensive solutions for the applications of photocatalytic technology for converting CO2 to CH4 as a whole are elaborated in this review.

“…[1][2][3] Titanium dioxide (TiO 2 ), recognized as one of the most important photocatalysts, has garnered extensive attention owing to its cost-effectiveness, alluring properties, and structural stability. 4,5 Nevertheless, its photocatalytic efficacy often falls short of expectations, primarily attributable to the wide bandgap and inefficient separation of photogenerated carriers. To enhance the photocatalytic performance of TiO 2 , it is imperative to devise efficient strategies that broaden its light absorption spectrum and overcome the kinetic constraints associated with photogenerated charge transfer.…”

“…The use of fossil fuels produces large amounts of CO 2 and increases the concentration of CO 2 in the atmosphere, − which causes a series of serious environmental problems. Using photocatalysts to convert CO 2 into organic products through solar energy is one of the best ways to solve this problem, like killing two birds with one stone to save our environment. − Various photocatalysts have been explored, including semiconductor materials such as TiO 2 , − Zn 2 GeO 4 , − ZnGa 2 O 4 , − etc. Although the photocatalytic activity of those catalysts has been gradually improved, the inherent physicochemical properties of traditional semiconductor materials limit further improvements in photocatalytic conversion efficiency, such as the poor adsorption performance of CO 2 , low specific surface area, and short lifetime of photogenerated carriers.…”

Incorporating high surface area and high CO 2 adsorption capacity of metal−organic frameworks (MOFs) together with highly efficient semiconductor photocatalysts provides an ideal strategy for designing CO 2 reduction photocatalysts. Controllable growth of TiO 2 nanoparticles on MIL-101(Cr) can be obtained and yields MIL-101(Cr)@TiO 2 core− shell photocatalysts via a fluoride-assisted solvothermal method. Corrosion occurs on the surface of MIL-101(Cr) by the action of F − and generates an activated surface, facilitating the growth of a TiO 2 shell. MIL-101(Cr)@TiO 2 nanocomposites with different TiO 2 contents are remarkably fabricated by controlling the reaction conditions. The morphology, structure, surface area, and composition of the as-prepared MIL-101(Cr)@TiO 2 nanocomposites are investigated by various characterization methods. The EDS mapping images reveal that the Ti and O elements are uniformly distributed on the shell, but Cr and C elements are mainly situated at the core of the composite, which further indicates the successful synthesis of the MIL-101(Cr)@TiO 2 core−shell structure. The photocatalytic conversion of CO 2 into CH 4 is noticeably enhanced by the produced MIL-101(Cr)@TiO 2 octahedra inheriting both large surface area (387.3 m 2 g −1 ) and high CO 2 adsorption capacity. Compared to pure TiO 2 nanoparticles under the same conditions, the optimized MIL-101(Cr)@TiO 2 photocatalyst exhibits a much greater CO 2 conversion efficiency, with a CH 4 generation rate of 0.22 μmol h −1 g −1 . This work will advance the experimental and theoretical basis for exploring highly efficient CO 2 reduction photocatalysts.
