3D structured TiO₂-based aerogel photocatalyst for the high-efficiency degradation of toluene gas

Abstract

Photocatalytic technology is a “green”, environmentally friendly, energy-saving technology, which is considered to be an ideal method for removing volatile organic compounds (VOCs). At present, photocatalytic technology mostly uses powdered...

A Comprehensive Study on the Synthesis and Characterization of TiO2 Nanoparticles Using Aloe vera Plant Extract and Their Photocatalytic Activity against MB Dye

“…The as-prepared TiO 2 NPs that were synthesized by utilising Aloe vera solution had a crystalline size of 27 nanometers. As a consequence of this, it is hypothesised that TiO 2 NPs have a larger surface area as well as dye molecules on their surface, which would lead to improved photocatalytic activity [33][34][35][36].…”

The Influence of SnO2 and Noble Metals on the Properties of TiO2 for Environmental Sustainability

“…The highest photocatalytic performance of the TS_Ag nanocomposite may be due to its high exciton lifetime [17], which can be clarified by the approaching of the Fermi level to the conduction band of the semiconductor. Consequently, a rapid electron transfer between Ag and the oxide matrix is assured, leading to the production of very reactive superoxide and hydroxyl radicals, which, in turn, enhance the photocatalytic activity of the TS_Ag nanocomposite [17,42]. Moreover, the high photocatalytic activity induced by the Ag nanoparticle-decorated matrix, in comparison to the other metal nanoparticle-decorated semiconductor matrices, was explained by Kaur et al, based on the high At the beginning of each experiment, the equilibrium of the MO adsorption process on the nanocomposite surface was achieved by keeping the photocatalyst aqueous suspensions in the presence of MO in the dark (for a duration of 30 min).…”
