Photocatalytic oxidation of the sulfur-containing compounds, trimethylene sulfide (C3H6S), propylene sulfide (C3H6S), thiophene (C4H4S), and methyl disulfide (C2H6S2), was carried out using an annular plug flow reactor with TiO2 in a supported form. Formation of products and byproducts was monitored in real time using a mass spectrometry online system. Mineralization of the sulfur-containing co...

The textile industry consumes considerable amounts of water during the dying and finishing operations. Dyes extensively used are found to be toxic and considered to be resistant to biodegradation. In this work a detailed investigation of heterogeneous photocatalytic degradation of Navy blue HE2R 1 (NB), azo dye of reactive class is presented using UV/P25TiO2/ZnO2/H2O2 process in aqueous suspens...

The sol-gel co-condensation of organo-phosphonates to titanium alkoxides enables access to novel organic-inorganic hybrids based on phosphonate-bridged titanium dioxide. In this contribution, we bring new perspectives to the long established sol-gel mineralization of titanium alkoxide species, by harnessing the virtues of the well-designed phosphonate-terminated phosphorus dendrimers as reactiv...

The long term performance of semiconductor-free activated carbons showing photochemical activity was explored by monitoring the photodegradation of phenol from aqueous solution along 20 hours of illumination in consecutive photocatalytic cycles. The efficiency of the process was evaluated in terms of phenol conversion, mineralization degree and evaluation of degradation intermediates upon cycli...

The possibility of linear alkyl benzene solfunate (LAS) photocatalytic degradation through application of TiO2 nanoparticles was investigated. 10(mg/L) of LAS has been affected by either UV or TiO2 and simultaneous use of both of them in separated experiments. Moreover, the effect of initial concentrations of LAS and TiO2, pH, present various anions and different UV power was studied to determi...

The kinetics of the photocatalytic degradation of 2-naphthol has been investigated in aqueous suspensions of titanium dioxide (TiO2) under a variety of conditions, which is essential from application point of view. The degradation was studied using different parameters such as types of TiO2, catalyst concentration, substrate concentration, reaction pH and in the presence of different electron a...

We report a comparative study on the photodegradation of the widely used benzodiazepine psychoactive drug alprazolam (8-chloro-1-methyl-6-phenyl-4H-[1,2,4]triazolo[4,3-a][1,4]benzodiazepine, ALP) using direct photolysis, and titanium dioxide photocatalyzed reaction. Titanium dioxide photocatalysts were prepared as nanoparticles by acidic sol-gel methods, calcined at two different temperatures, ...

Fe-BiOCl-Vo nanosheets with electron-capture centers of doped Fe and surface oxygen vacancies (Vo) for enhanced photocatalytic-Fenton performances were conducted. Compared pristine BiOCl nanosheets, the band gap resulting was narrowed, defective bands introduced due to doping Vo. Furthermore, integrated electron trapping effect Vo can efficiently drive charge transfer separation. As a result, p...

Exploring a sustainable route for the efficient treating/recycling of heavy metal (like Ni2+, Cd2+, Cu2+) contamination water is highly desirable both from environment and resource view. Herein, we reported scale-up synthesis monolayer magnesium-aluminium layered double hydroxide (m-MgAl-LDH) nanosheets, which showed exceptional ability to mineralize Cd2+ Cu2+ rapidly efficiently. Furthermore, ...
