Preparation of graphene film decorated TiO2 nano-tube array photoelectrode and its enhanced visible light photocatalytic mechanism

A facile and novel strategy to synthesize reduced TiO2 nanotubes photoelectrode for photoelectrocatalytic degradation of diclofenac

“…Seen from Fig. 1d, the as-fabricated pristine TiO 2 NTs exhibited typical UV light absorption spectrum, corresponding to the electronic transition from O 2À anti-bonding orbital to the lowest empty orbital of Ti 4þ (O2p / Ti3d) (Cheng et al, 2014). Besides, pristine TiO 2 NTs also displayed broad light absorption around 410e800 nm, probably caused by the following aspects including the trapped charge carriers or some color centers, as well as the absorption of incident light by the nano-tubes (Zhuang et al, 2007).…”

Construction of high-efficient photoelectrocatalytic system by coupling with TiO 2 nano-tubes photoanode and active carbon/polytetrafluoroethylene cathode and its enhanced photoelectrocatalytic degradation of 2,4-dichlorophene and mechanism

“…As demonstrated later, anodized potential usually determines the growth and geometrical parameters of TiO 2 NTs [20,21]. Thus, the effect of anodized potential on the formation of TiO 2 NTs was performed by varying the applied potential.…”

Organic pollutants removal in wastewater by heterogeneous photocatalytic ozonation

“…Researchers extensively use the referred paths to modify titana films. Doped, deposited or compounded mesoporous thin films (Xiang et al, 2013;Wang et al, 2013c;Cheng et al, 2014;Elgh and Palmqvist, 2014;Fakhouri et al, 2014) are the most acclaimed. Varied methods are reported for the realization of the preparation strategies.…”
