A review on TiO_2−x-based materials for photocatalytic CO₂ reduction

Abstract

Photocatalytic CO2 reduction technology has a broad prospect in dealing with the issues of energy shortages and global warming. As a widely studied material used in photocatalytic process, titanium dioxide...

Oxygen vacancies assist a facet effect to modulate the microstructure of TiO2 for efficient photocatalytic O2 activation

“…Defects with different structures inevitably exist in semiconductor materials. 1,2 Recent studies demonstrated that defect engineering can effectively tune the microstructure of materials, making them suitable for multi-domain applications, especially in photocatalysis. [3][4][5][6] Among many defect structures, zero-dimensional point defects (atom vacancy) have a more sensitive effect on the microstructure of materials.…”

Single-site bipyridine cobalt complexes covalently embedded into graphitic carbon nitride with excellent photocatalytic activity and selectivity towards CO2 reduction

“…Thus, the design and fabrication of cheap, stable photocatalysts with high activity and selectivity is the key to CO 2 reduction. 7–12…”

The Role of Surface Hydroxyls in the Mobility of Carboxylates on Surfaces: Dynamics of Acetate on Anatase TiO2(101)

“…In particular, titania has drawn significant attention as a model system to provide general insight into the chemistry of oxide surfaces. [1][2][3][4] Titania is a versatile reducible oxide that is used in numerous catalytic applications, including water splitting, [5][6][7] alcohol oxidation, 8,9 CO2 reduction, [10][11][12] and ketonization. [13][14][15][16] While rutile is the lowest energy polymorph of titania, anatase is more stable in a nanoparticulate form due to the lower surface energies.…”
