Jan 1, 2021 · Sometimes over TiO 2 -based systems, a synergetic effect of the two processes, in the so-called photo-thermocatalysis, has been observed, with highly positive advantages. TiO 2 is a semiconductor of n -type, and it is well known for its high (photo)chemical stability and high ultraviolet absorption.

Dec 25, 2022 · CeMn x O y /TiO 2 showed high photothermal catalytic activity for the oxidation of benzene, which was comparable to the expensive noble metal catalyst (0.5% Pt/Al 2 O 3) and much higher than CeO 2 /TiO 2 and MnO x /TiO 2 nanocomposites with the …

Jul 14, 2023 · In order to extend the photoactivity of titanium dioxide into the visible region, highly porous nitrogen-doped TiO2 catalysts (NTiO2) were successfully synthesized by a modified co-pptn. method with ammonium hydroxide as a nitrogen source.

Hydrogen produced from water using photocatalysts driven by sunlight is a sustainable way to overcome the intermittency issues of solar power and provide a green alternative to fossil fuels. TiO 2 has been used as a photocatalyst since the 1970s due …

While Titanium dioxide (TiO 2) photocatalyst exhibits excellent properties, its high band gap limits absorption to ultraviolet (UV) irradiation, resulting in low photo conversion efficiency. This review explores various modification techniques aimed at enhancing the efficiency of TiO 2 …

Sep 22, 2022 · Owing to its non-toxicity, cost-effectiveness, high abundance, and excellent stability, as well as presence of rich, tunable, and reliable anchor sites for metal SA, TiO 2 has been extensively explored as a superior support for SACs.

This review focuses on the recent development of TiO 2 as a catalyst in green organic synthesis including in hydrodeoxygenation, hydrogenation, esterification/transesterification, the water–gas shift reaction, and visible light-induced organic transformation owing to its strong metal-support interaction (SMSI), high chemical stability ...

Apr 18, 2023 · Herein, Pt catalysts on a TiO 2 support with different crystal phases (rutile, anatase, and mixed phase (P25)) were prepared for catalytic oxidation of 1,2-dichloroethane (DCE). The Pt catalyst on P25-TiO 2 (Pt/TiO 2 -P) showed optimal activity, selectivity, and stability, even under high-space velocity and humidity conditions.

Recently, titanium oxide (TiO2) was introduced as an alternative support material for heterogeneous catalyst due to the effect of its high surface area stabilizing the catalysts in its mesoporous structure.

Oct 14, 2014 · The open structure of metal/metal oxide supported TiO 2 catalyst favor efficient heat and mass transfers between the gaseous reactants, the catalytic active phase, and the wall of the chemical reactors.
