TiO_2−x prepared by radio-frequency thermal plasma: optical switching of hydrophilicity and hydrophobicity used in the efficient recovery of photocatalysts

Abstract

A TiO2−x catalyst synthesized using radio-frequency thermal plasma can switch between hydrophilic and hydrophobic properties. Its dispersion and agglomeration can thus be adjusted so that it is dispersed evenly or forms floating balls, which is convenient for recycling.

Thermal plasma-synthesized gray-black TiO2 with abundant oxygen vacancies for high-efficiency solar desalination

“…Our autonomously designed plasma apparatus facilitates largescale, continuous feedstock processing and production. 39 As shown in the Fig. S1, † the G-TiO 2 produced can achieve a production rate of 18.4 g min −1 , and the production rate of more than 1 kg h −1 .…”
