]. Surface modification of the TiO 2 nanoparticles contributes greatly to boost the photocatalytic degradation of polyethylene. Lue et al. reported that the modified TiO 2 with various polymers such as polyethylene glycol, polyacrylamide, polymethyl methacrylate, and polyaniline ameliorated the degradation of polyethylene under UV exposure because of the better dispersion and improved hydrophilicity compared with the untreated TiO 2 [ 5 ], [ 19 ], [ 20 ], [ 21 ]. Considerable attempts such as doping, surface modification, dye sensitization, noble metal, and non

-Fenton method [ 11 ]. Light and electricity have played extremely important roles in the degradation of antibiotics, and have an extremely important role confirmed in lots of reports. Therefore, photocatalysis is an effective method used for degradation of antibiotics, until now, which is primarily concerned with designing novel catalysts . The titanium dioxide (TiO 2 ), zinc oxide (ZnO), cadmium sulfide (CdS) and ferric oxide (Fe 2 O 3 ) were commonly used as catalyst in amoxicillin photocatalytic degradation process [ 12 ]. Considering the limited performance for pure

Gas-Phase Photocatalytic Degradation of Trichloroethylene -Relation with Photochemical Reactions- Masayuki M urabayashi, Kiminori Itoh, and Kouichi Kawamura Graduate School of Environment and Information Sciences, Yokohama National University, Yokohama 240- 8501,Japan Abstract: Applications of photocatalytic reactions are now being developed widely for various purposes. These reactions have been especially successful in the remediation of groundwater and soil polluted with organic chlorine compounds. The degradation reactions of these compounds in the gas

The Effects of the Pre-treatments on the Photocatalytic Degradation of Trichloroethylene in the Gas-Phase Masayuki Murabayashi, Kiminori Itoh, Zhao Lian Hua, and KotaKitahara Institute of Environmental Science and Technology Yokohama National University, Yokohama 240-8501, Japan Abstract: The effects of pre-treatment of Ti02 photocatalyst on gas-phase degradation of trichloroethylene (TCE) and ethyl alcohol (EtOH) were studied, by using a batch reactor. Pre-illumination of the photocatalyst with black-light fluorescent lamps accelerated the photocatalytic

. [ 10 ] to study the photocatalytic degradation efficiency. Test results showed that the diatom-FeOx composite exhibited high activity in catalyzing the photodegradation of Rh-6G. Zhang et al . [ 11 ] evaluated and discussed the effects of nano-SiO 2 on the photocatalytic behavior and durability of cementitious composite incorporated with nano-SiO 2 . The results indicated that the nano-SiO 2 could dramatically improve the photocatalytic performance and durability of cementitious composites. Samim et al . [ 12 ] discussed and compared the visible light

remain on the surface of the road and spread in the air voids of the pavement, which could result in a decrease in the friction coefficient of the road, affect driving safety, and cause damage to pavement materials over time, and thus reduce the service life of the road [ 4 ]. At the same time, on the road surface polluted by the oil spill, the road runoff formed by rain erosion will cause secondary pollution of the surrounding soil and water. The photocatalytic degradation is a safe, long-lasting, and sustainable technology in the treatment of air pollutions [ 5 , 6
