Advances for CO2 Photocatalytic Reduction in Porous Ti-Based Photocatalysts

The photoreduction of CO2 into high value-added fuels is a prospective approach for dealing with energy depletion and global warming from the root. Ti-based photocatalysts with porous structures have aroused wide concern due to the potential advantages like high specific surface area, cost-effective, earth-abundant, nontoxicity, and so on. This review presented the current achievements on porous TiO2, Ti-based zeolites, and Ti-based metal-organic frameworks for CO2 photoreduction. Multiple modification methods (such as heterojunction construction, cocatalyst modification, element doping, and surface adjustment) for optimizing the performance of these Ti-based materials are discussed. Finally, challenges and perspectives of porous Ti-based photocatalysts for CO2 photoreduction are proposed. This review is expected to provide directions for researchers to design and exploit more efficient materials for photoenergy conversion.
