As photons from the UV light shine on the catalyst, a reaction occurs creating ions that decontaminate air and surfaces. 2010-01-01 The Photocatalytic Oxidation process combines UV irradiation with a substance (catalyst) titanium dioxide (TiO2) which results in a reaction that changes malignant contaminants into water, carbon dioxide and detritus. Photocatalytic water oxidation by persulfate (Na 2 S 2 O 8) with [Ru(bpy) 3] 2+ (bpy=2,2′‐bipyridine) as a photocatalyst provides a standard protocol to study the catalytic reactivity of water oxidation catalysts. The yield of evolved oxygen per persulfate is regarded as a good index for the catalytic reactivity because the oxidation of bpy of [Ru(bpy) 3] 2+ and organic ligands of The highly hydrophilic COF material (TFPT-BMTH) was constructed by pore surface functionalizing strategy, and exhibited excellent porosity, high crystallinity, and good thermal and chemical stability.The resulting COF exhibits significant catalytic activity and recyclability together with environmental benignity in photocatalytic oxidation of benzylamine in water under ambient conditions. Increased concentrations of natural organic matter (NOM), a complex mixture of organic substances found in most surface waters, have recently emerged as a substantial environmental issue.

The advantage of this method is that it can be effective at very low temperature (less than 100 °C) and may be used simultaneously towards various air pollutants such as volatile organic compounds (VOCs). photocatalytic oxidation processes to aid the OPW treatment, thus can achieve both high efficiency in removal of PAHs, and low toxicity and high biodegradability of the effluent. The matrix effect was first investigated in a suspensive photocatalytic oxidation system, in which the synthesized TiO 2 nanoparticles were used.

The role of primary active species (ecb−, hvb+, •OH, HO2•, O2•−, and H2O2) during photocatalytic degradation of paracetamol (acetaminophen) using TiO2 catalyst was systematically investigated. Hydroxyl radicals (•OH) are responsible for the major degradation of paracetamol with a second-order rate constant (1.7 × 109 M−1 s−1) for an •OH−paracetamol reaction.

Arsenite oxidation in UV-illuminated TiO 2 suspension was highly efficient in the presence of dissolved oxygen. Volatile organic compounds (VOCs) are the major group of indoor air pollutants, which significantly impact indoor air quality (IAQ) and influence human health. Photocatalytic oxidation (PCO) is a cost-effective technology for VOCs removal, compared with adsorption, biofiltration, or thermal catalysis method. Development of active photocatalyst systems is crucial for the PCO reaction.
