TL;DR: In this paper, flexible BiOCl nanosheets with oxygen vacancies (BOC-OV) were successfully prepared and the enhanced exciton dissociation resulted in the superior CO2 conversion under UV-Vis light irradiation, where the light to carbon monoxide conversion efficiency reached up to 26.5 × 10−6.

TL;DR: In this article, oxygen vacancies are induced in MoO3 for improving photo-thermal CO2 reduction efficiency by capturing near-infrared (NIR) photons, which can promote the carrier separation, improve CO2 adsorption on the defective surface and lower the barrier of CO2 hydrogenation during the conversion process.

TL;DR: In this paper, Ni2+ was photoreduced to Ni particles and deposited on graphite carbon nitride (g-C3N4) under vacuum, and the surface of Ni particles was oxidized to form an NiO shell after the samples were exposed to air.

TL;DR: The main mechanism research methods, such as in situ Fourier transform infrared (FTIR) spectroscopy and theoretical calculations, are presented and the main challenges and research trends reported in studies of Bi-based photocatalysts for photoc atalytic CO2 conversion are discussed and summarized.

TL;DR: In this paper, a photocatalytic system for sulfide oxidation to sulfoxides with high yields under blue LED irradiation was presented, which was carried out in water with oxygen over a bismuth-rich catalyst of Bi4O5Br2.
