In the present work, UVA light-driven g-C3N4/TiO2 photocatalyst was synthesized for photodegradation of Carbamazepine (CBZ) in aqueous medium. The morphological, optical properties and structure TiO2, g-C3N4 prepared composites were analyzed using X-ray diffraction (XRD), Nitrogen adsorption–desorption isotherm based on BET, Raman Spectroscopy, Scanning Electron Microscopy (SEM) with EDX, UV–vi...

titanium dioxide (tio2)nanoparticles have been frequently employed in the environmental treatment and purification purposes as a cheap and highly efficient photocatalyst. a photocatalyst can facilitate the breakdown and removal of a variety of environmental pollutants at room temperature. tio2 photocatalyst is the best candidatebecause of its strong oxidized ability, non-toxicity and longtherma...

photocatalytic decolorization of methyl orange (mo) solution has been studied using phosphotungstic acid (hpa) as photocatalyst. the decolorization reaction of mo solution is photocatalysis. the paper reveals that the optimal loading of photocatalyst for decolorization of mo solution (10 mg/l) is 0.6 g/l. the results show that the photocatalytic decolorization reaction of mo with hpa in a homog...

Nickel nanoparticle-decorated phosphorous-doped graphitic carbon nitride (Ni@g-PC₃N₄) was synthesized and used as an efficient photoactive catalyst for the reduction of various nitrobenzenes under visible light irradiation. Hydrazine monohydrate was used as the source of protons and electrons for the intended reaction. The developed photocatalyst was found to be highly active and afforded excel...

Despite a well-developed and growing body of work in copper catalysis, the potential of copper to serve as a photocatalyst remains underexplored. Here we describe a photoinduced copper-catalyzed method for coupling readily available racemic tertiary alkyl chloride electrophiles with amines to generate fully substituted stereocenters with high enantioselectivity. The reaction proceeds at -40°C u...

Rhodamine B (RB) is a toxic dye used extensively in textile industry, which must be remediated before its drainage to environment. In the present study, supported gold nanoparticles on commercially available titania and zincite were successfully prepared and then their activity on the photodegradation of RB under UV A light irradiation were evaluated. The synthesized photocatalysts were charact...

Cryptosporidium parvum and Giardia lamblia are two of the most chlorine resistant microorganisms with notable adverse effects on humans. Our study shows that waters containing these two protozoa at low concentrations can be efficiently disinfected in continuous flow by using a commercial fibrous ceramic TiO(2) photocatalyst. The efficiency of the photocatalytic disinfection is largely enhanced ...

introduction: textile industries produce large volume of colored dye effluents which are toxic and removal of dyes from wastewater is a significant environmental issue. advanced oxidation process (aops) is alternative method for the complete degradation many organic pollutants. zno and tio2 are important photocatalysts with high catalytic activity that have attracted much research attention. ma...

Heteroarylation via C-H functionalization has been synthetically challenging, but such transformations represent an atom-economical and highly convergent route toward complex molecules. Reported herein is a photoredox-catalyzed coupling between 2-trifluoroborato-4-chromanones and various heteroarenes through a Minisci pathway. Mesitylacridinium perchlorate, an organic photocatalyst, proved to b...
