“…Huan et al (2007) tested the decomposition of 4-CP (C o ¼ 13 mg/L) using N-doped TiO 2 under visible light and achieved 63.5% degradation within 6h irradiation. Kun et al (2009) examined the photocatalytic activity of phenol (C o ¼ 0.5 mmol/L) under visible light with N-doped TiO 2 and found that acid treated NeTiO 2 showed higher catalytic activity after 2 h irradiation. Under visible light, Ananpattarachai et al (2009) investigated the photocatalytic efficacy of NeTiO 2 prepared with different nitrogen dopants for the degradation of 2-CP.…”

In recent years, the application of heterogeneous photocatalytic water purification processes has gained wide attention due to its effectiveness in degrading and mineralizing the recalcitrant organic compounds as well as the possibility of utilizing the solar UV and visible-light spectrum. This paper aims to review and summarize the recent works on the titanium dioxide (TiO(2)) photocatalytic oxidation of pesticides and phenolic compounds, predominant in storm and wastewater effluents. The effects of various operating parameters on the photocatalytic degradation of pesticides and phenols are discussed. Results reported here suggest that the photocatalytic degradation of organic compounds depends on the type and composition of the photocatalyst and, light intensity, initial substrate concentration, amount of catalyst, pH of the reaction medium, ionic components in water, solvent types, oxidizing agents/electron acceptors, catalyst application mode, and calcination temperature in the water environment. A substantial amount of research has focused on the enhancement of TiO(2) photocatalysis by modification with metal, non-metal and ion doping. Recent developments in TiO(2) photocatalysis for the degradation of various pesticides and phenols are also highlighted in this review. It is evident from the literature survey that photocatalysis has good potential to remove a variety of organic pollutants. However, there is still a need to determine the practical utility of this technique on a commercial scale.

“…The apparent rate constant is determined by fitting the pseudo-first-order reaction model of MB de-colorization according to Eq. (6). On the other hand, the photocatalytic activity is simultaneously contributed by the specific activity and specific surface area of photocatalysts.…”

“…Besides, some researchers have retarded the phase transformation by doping TiO 2 with metallic or nonmetallic ions [7,11]. However the introduction of dopants not only changes the intrinsic properties of TiO 2 but also generates secondary impurity phase which acts as a recombination center and therefore reduces the photocatalytic activity of TiO 2 [6,16].…”
