TL;DR: In this article, the authors summarized the widely accepted pathways of photocatalytic CO2 reduction reactions and analyzed the important factors affecting product selectivity, mainly including light-excitation attributes, band structure of photocATalysts, separation of photogenerated charge carriers, adsorption/activation of reactants, surface active sites of catalytic reaction, and adaption/desorption of intermediates.

TL;DR: In this paper, a rice crust-like structure was achieved through the uniform distribution of TiO2 nanoparticles on MXene Ti3C2 through calcination method and a unique rice crustlike structure of the prepared samples rendered the composite with large population of the surface active sites.

TL;DR: In this article, the photocatalytic activity of titania powders with high photocatalysis was investigated by hydrolysis of titanium tetraisopropoxide in the presence of HNO3 or NH4OH under ultrasonic irradiation.

TL;DR: In this article, a simple precipitation method using Degussa P25 TiO2 powder (P25) as a support and copper nitrate as a precursor was used to obtain a photocatalytic H2-production rate of 3418 μmol h−1 g−1 with a quantum efficiency of 13.9%.

TL;DR: The photocatalytic activity of the as-prepared nanocrystalline mesoporous TiO2 powders was evaluated by the degradation of acetone (CH3COCH3) under UV-light irradiation at room temperature in air as mentioned in this paper.
