Review ArticleOpen accessEvery word in the titleDisinfection of Water using Supported Titanium Dioxide PhotocatalystsShamkumar Pandurang Deshmukh, Dattatray Krishna Dalavi, Yuvaraj Mohan HungeTiO2 based photocatalyst has potential material for disinfection of harmful pathogens as well as removal of organic compounds. The formation of reactive oxygen species is a key part for overall process but aggregation and band gap constraint explore a new dimension to use of support for propounding its physicochemical properties. Therefore, the modification of TiO2 using various support alters photocatalytic … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 28 Dec 2020 · 7,266 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Removal of 4-Chlorophenol and Dichloroacetic Acid in Water Using Ti-, Zr- and Ti/Zr-Pillared Bentonites as PhotocatalystMohamed Houari, Mohamed Saidi, Djamel Tabet et al.Heterogeneous photocatalysis could be alternative remediation technology for water since it does not need the addition of any chemicals and it is suitable for treating low concentrations of pollutant. Although the TiO2 Degussa P 25 is most used photocatalyst its photonic efficiency still low and its recovery from water is considered as an awkward process. In this study the effect … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 7,523 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTiO2 Nanoparticles-Coated Polypropylene Copolymer as Photocatalyst on Methylene Blue Photodegradation under Solar ExposureHasniah Aliah, Mahardika Prasetya Aji, Masturi et al.Problem statement: Pollutions of water bodies by dye wastes from textile industries and other sources have become critical consideration. A photocatalytic technique using semiconductor materials such as Titanium Dioxide (TiO2) activated by lights has been considered as one economical method to solve this problem. Approach: We attached titanium dioxide on the surface of polymer grains as photocatalyc agents using a … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 29 May 2012 · 7,861 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDegradation of Textile Dyes Ponceau-S and Sudan IV Using Recently Developed Photocatalyst, Immobilized Resin Dowex-11R. C. Meena, Ram Babu Pachwarya, Vijay Kumar Meena, Shakuntla AryaProblem statement: In present study, we selected a model dyes Ponceau S and Sudan IV, to test a recently developed photo catalyst methylene blue immobilized resin dowex-11. Approach: This is a light-activated process that has been successfully applied to remove organic and inorganic dyes of textile industries. Results: The reactor, made of glass slides (tubes) coated with a thin-film of … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,059 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCarbon Nanodots from Frying Oil as Catalyst for Photocatalytic Degradation of Methylene Blue Assisted Solar Light IrradiationMahardika Prasetya Aji, Pradita Ajeng Wiguna, Siti Aisyah Suciningtyas et al.Carbon nanodots (C-Dots) of frying oil could be a photocatalyst for the degradation of methylene blue solution with assisted solar light irradiation. C-Dots of frying oil were resulted from the heating process at T = 300C for 2 h. C-Dots of frying oil were used as a catalyst in methylene blue solution with variations the number of C-Dots and the … …American Journal of Applied Sciences, Vol. 13, Issue 4 · 28 Apr 2016 · 7,701 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhotocatalytic Activity and Antibacterial Behavior of Fe3+-Doped TiO2/SnO2 NanoparticlesLek Sikong, Budsabakorn Kongreong, Duangporn Kantachote, Weerawan SutthisripokProblem statement: Since bacteria mainly causes damage on fresh vegetables and fruits during transportation to market, anti-bacterial TiO2 photocatalyst was applied for their packaging films. However, it has been known that pure TiO2 exhibits low photocatalytic property due to rapid recombination of photo-activated electrons and holes. Doping with metal or metal oxide shows the improvement of photocatalytic activity and disinfection … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 15,242 accessesView PDFCite
Research ArticleOpen accessIn the abstractNano TiO2 Deposited on Crude Mineral and the Photoactivity to the Degradation of ChloroformHaiyan Song, Hongfu Jiang, Xingqing Liu, Guangyao MengSupported TiO2 catalysts have increasingly attracted intention in recent years because of their potential application to photocatalytic degradation of organic pollutants in water and air. In this work, nano TiO2 particles deposited on crude nonmetallic mineral were prepared by a Sol-gel process, the photocatalyst for degradation of chloroform was tested and optimized with respect to TiO2 loading, catalyst dosage and … …American Journal of Environmental Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 7,374 accessesView PDFCite
