Photocatalytic degradation of methylene blue by a combination of TiO2-anatase and coconut shell activated carbon

A novel biotemplated synthesis of TiO2/wood charcoal composites for synergistic removal of bisphenol A by adsorption and photocatalytic degradation

“…One kind of approach is a simple physical mixing of AC and TiO 2 [33][34][35][36][37], or using organic binder to bind them together [38]. The TiO 2 /AC composites, which were prepared by simple mixing solid AC and solid TiO 2 without using binder, ϱ had weak binding ability between solid titanium dioxide and solid activated carbon.…”

Reduced graphene oxide and Ag wrapped TiO2 photocatalyst for enhanced visible light photocatalysis

“…[4][5][6] It is well established that this process dominantly employs TiO 2 semiconductor owing to its high synergetic oxidation strength, zero toxicity, and greater chemical and biological stability. [7][8][9] In spite, it has major obstruction with wider bandgap energy (3.2 eV) and allows the photoactivation to only in the UV spectrum (λ < 390 nm). It also possess very low lifetime for the charge carriers and leads to a faster recombination rate.…”

Activated Charcoal Supported Cadmium Doped TiO₂ for Photocatalytic and Antibacterial Applications

“…In water, UV-irradiated Cd-TiO 2 is able to completely destroy organic contaminants through the TiO 2 activation, according to the following reaction. The electron and the hole are generated in the conduction band and in the valence band of TiO 2 by UV irradiation, respectively [32]. The positive hole can oxidize hydroxide ions (or water molecule) adsorbed on the surface of TiO 2 particles to produce hydroxyl radical [33], the electrons of conduction band can react with the oxygen to produce superoxide radical anions [34].…”
