Doctoral Thesis / Dissertation from the year 2011 in the subject Chemistry - Materials Chemistry, East China University of Science and Technology (-), language: English, abstract: Considerable effort has been made to design, fabricate, and manipulate nanostructured materials by innovative approaches. The precise control of nanoscale structures will pave the way not only for elucidating unique size/shape dependent physicochemical properties but also for realizing new applications in science and technology. Nanotechnology offers unprecedented opportunities for improving our daily lives and the environment in which we live. This thesis mainly describes recent progress in the design, fabrication, and modification of nanostructured semiconductor materials for environmental applications. The scope of this thesis covers TiO2, Bi2O3 and BiOCl materials, focusing particularly on TiO2-based nanostructures (e.g., pure, doped, coupled, mesoporous, hierarchically porous, and ordered mesoporous TiO2). Mesoporous titania is of particular interest since this class of materials possesses well-defined porosity and large specific surface areas. For photocatalytic degradation of organics, these desirable properties are anticipated to improve the efficiency. So in the first part of work, I have synthesized the mesoporous titania by using poly ethylene glycol as a template in dilute acetic acid aqueous solution by hydrothermal process and investigated the effect of PEG molecular weights and thermal treatment on the resultant structure and photocatalytic activity. When the molecular weights of PEG vary from 600 to 20,000, the particle sizes of mesoporous-TiO2 structure decrease from 15.1 to 13.3 nm and mean pore sizes increase from 6.9-10.6 nm. The activities of these mesoporous-TiO2 photocatalysts prepared by using PEG are evaluated and compared with Degussa P-25 using chloro-phenol as a testing compound. [...]

Today's technology has to aim at the environmental conscious development with new, environmentally friendly processes and materials. Nanotechnology presents eligible solutions to the challenges of modern materials science. It deals with small amount of matter (e.g. thin film), which - by its nanostructure and/or unusual composition - provides traditional bulk materials with new or improved functionalities. The aim of the present work was to elaborate multifunctional nanostructured thin layers for possible application as a) self-cleaning antireflective coating and b) active top layer on porous ceramic membranes coupling separation and photocatalysis or separation and chemisorption. Wet colloidal chemistry routes were used for the synthesis of silica, ZnO and silica/ZnO core/shell nanoparticles. Self-cleaning, antireflective coatings were obtained with Langmuir-Blodgett technique. Porous ceramic membranes were prepared for the coupling of separation with photocatalysis and separation with chemisorption using the dip coating technique.
