Hydrothermal synthesis of carbon quantum dots using different precursors and their combination with TiO2 for enhanced photocatalytic activity

Ceramics International, 2018
In this study, carbon quantum dots (CQDs) were successfully synthesized by a facile and green hydrothermal method, and further coupled with P25 (commercial TiO 2 ) to form CQDs/P25 heterojunctions for enhanced photocatalytic activity.

Oxygen Vacancy Generation and Stabilization in CeO2–x by Cu Introduction with Improved CO2 Photocatalytic Reduction Activity

ACS Catalysis, 2019
Introducing O vacancies into the lattice of a semiconductor photocatalyst can alter its intrinsic electronic properties and band gap, thus enhancing the visible light absorption, promoting the separation/transfer of photogenerated charge carriers, and ...

Solar-active photocatalytic tandems. A compromise in the photocatalytic processes design

Materials Science in Semiconductor Processing, 2016
Abstract The quest for Vis- or solar-active photocatalytic materials and working systems led to various solutions, aiming at high process efficiency, towards mineralization. This involves the pH-adjustment (supporting the pollutant adsorption on the photocatalyst) and the addition of electron trappers, as H 2 O 2 . While these may be effective on the

[Study of photocatalytic activity, characterization and preparation of supersuspended nano-TiO2 (II) photocatalytic activity].

Guang pu xue yu guang pu fen xi = Guang pu, 2010
The photocatalytic activity of nano-TiO2 prepared by pyrolysis method and then by cooling-treatment in silicon oil and in air respectively was studied with methyl-orange solution as model waste water. The results show that the photocatalytic activity of both products is obvious with no great difference.
