Phenol degradation using an anodized graphene-doped TiO2 nanotube composite under visible light

The application of photoelectrocatalysis in the degradation of rhodamine B in aqueous solutions: a review

“…For example, boron, nitrogen, graphene, nitrogen and fluorine are common non-metal dopants that have been used to promote visible light absorption in TiO 2 . 65–67…”

“…For example, boron, nitrogen, graphene, nitrogen and uorine are common non-metal dopants that have been used to promote visible light absorption in TiO 2 . [65][66][67] In the last few years, the use of visible light-active metal oxide semiconductors as photoanode materials in PEC has been embraced. These materials have narrow band gaps and can easily absorb photons for excitation within the visible light spectrum, and their use encourages the adoption of direct sunlight as a suitable light source for PEC degradation systems.…”

Recent Progress in Anodic Oxidation of TiO2 Nanotubes and Enhanced Photocatalytic Performance: A Short Review

“…The recombination of charges eand h + is reduced, more hydroxyl radicals and peroxides (O 2-) are generated, and the photocatalytic degradation of organic matters is promoted. 182 It has been reported that many TiO2 nanotubes are decorated or filled with different foreign materials. [183][184][185] In recent years, the photocatalytic activity of TiO2 nanotubes has been enhanced by constructing heterojunction (more than two layers of different semiconductor thin films are deposited on the same substrate in turn).…”

Photoelectrochemical and photocatalytic activities of improved TiO2 nanotubes using Ag+ ion implantation and RGO deposition

“…Ternary composite based on the deposition of reduced graphene oxide (RGO) on metal-TiO 2 is an effective way to further enhance catalytic activities. RGO, a two-dimensional form of carbonaceous material, has attracted much intention in the modification of TNTs because of its high electron mobility and π-conjugated structure [32][33][34][35]. Thus, RGO is a brilliant electron acceptor and transporter which is frequently used to efficiently suppress the recombination of photogenerated electron-hole (e − -h + ) pairs.…”
