Abstract: Dye sensitized semiconductor can constitute efficient photochemical systems for the environmental remediation. Using metal free phthalocyanines (H2Pc) and metallophthalocyanine (MPc) complexes, has attracted much interest owing to its high stability, visible light photosensitivity and catalytic properties. Phthalocyanine sensitized titaniumdioxide (Pc/TiO2) catalyst is able to achieve the degradation of many organic pollutants by visible light as energy and O2 in the air as the oxidant under ambient conditions. Owing to above mentioned properties, H2Pc and MPc immobilized TiO2 photocatalysts have been tested for photocatalytic removal of organic and inorganic pollutants. In this review, production, characterization and application of Pc/TiO2 catalysts are described and particularly focused on the studies concerning the photocatalytic applications either in the form of nano dust for suspension applications or thin film. Pollutants were classified into two main groups; namely organic toxic pollutants and dyes.

Abstract: In this study, the nano rods of molybdenum oxide were prepared by the thermo chemical method. The prepared molybdenum oxide nano rods were characterized by UV-Visible spectrophotometer, band gap energy, FT-IR spectrophotometer, XRD, SEM, and TEM techniques. The prepared molybdenum oxide nano rods were used for anti bacterial activity. The XRD analysis showed the formation of crystalline nano rods. The FT-IR and UV-Vis analysis give the peak at 1120 cm-1 and 246 nm which confirm the formation of nano rods. The SEM and TEM analysis also confirmed the formation of nano rods. The band gap energy of MoO3 nano rods were observed 3.67, 3.54, 3.45 and 3.36 eV at 400, 500, 600 and 700°C temperatures. The MoO3 nano rods gave the positive antibacterial activity against S. Aureus pathogens.
