Enhanced oxidation of microcystins using TiO2–O3: Kinetics and mutagenic assay

Photocatalytic ozonation of 4-chloro-2-methylphenoxyacetic acid and its reaction intermediate 4-chloro-2-methyl phenol

“…TiO2 can act as a catalyst in ozonolysis reactions by accelerating the ozone decomposition into radical species. Alternatively, oxidation reactions can take place on the solid surface decreasing the activation energy of the ozonolysis [18], [19], [20], [21].…”

Inhibition of Nano-Metal Oxides on Bromate Formation during Ozonation Process

“…von Gunten (2003a) has reported that the instantaneous decomposition was characteristic for aqueous ozone in the initial phase, which led to significant production of OH radicals. Hsu et al (2013) also have investigated that TiO 2 significantly increased the production rate of OH radicals by initiating the decomposition of ozone on the catalyst surface. Results obtained by Yang et al (2011) indicate that the Ce X Zr 1-X O 2 mixed oxides significantly promoted the dissolved O 3 decomposition and produced OH radicals in the ozonation.…”

“…TiO 2 significantly increased the rate of production of OH radicals by initiating the decomposition of ozone on the catalyst surface (Hsu et al 2013). In the meanwhile, the partial OH radicals would rapidly generate hydrogen peroxide (Milne et al 2013), which would further promote dissolved O 3 decomposition and lower residual ozone concentration.…”
