Preparation and Photocatalysis of Schlumbergera bridgesii-Like CdS Modified One-Dimensional TiO2 Nanowires on Zeolite

In recent years, composite semiconductor photocatalytic materials have received significant attention as a novel type of materials and technical means. So in this work, CdS-modified TiO2 nanowires are fabricated on natural zeolite by simple sol-gel and hydrothermal synthesis method. This novel composite semiconductor photocatalytic material has almost solved the shortcomings of pure TiO2, such as easy cohesion, low utilization rate, and exceedingly weak photocatalytic activities under visible light. The degradation efficiency of methylene blue dye in water is near to 90% with CdS-modified TiO2 nanowires/zeolite composite materials after 60 min under visible light, which indicated its huge potential application in wastewater treatment.

Research on Preparation and Properties of Textile Materials Deposited with Nanostructured Titanium Oxide

In the 21st century, environmental pollution has become increasingly serious. Pollution control and management has been the major issue and must be resolved. In this paper, TiO2 as a representative oxide semiconductor photo catalytic material, which is an ideal environmental pollution cleaning product due to its unique properties. The low temperature magnetron sputter coating was employed to deposit Nanostructured TiO2 films on the surface of nonwovens and polymer fibers to functionalize the textile materials. The use of magnetron sputter coating not only overcame the problems of Nanoparticle aggregation as filling particles, but also shortened the production processes and eliminated the water pollution. The use of magnetron sputter coating, on the other hand, could cut the processing cost. This research explored the formation principle, preparation techniques, properties and reliability of the Nanostructured TiO2 deposited on the surface of textile substrates to meet the demands of the markets for functional textiles.
