Preface

Abstract

The aim of the Symposium was to give an overview of the present status with regard to historical background and to foresee the future trends in the field of photocatalyst research. Serious global and environmental problems have led the ceramics manufacturing industries to closely monitor the formation and accumulation of carbon dioxide and other toxic gases in the atmosphere, the reduction of raw materials, the consumption of energy, and other factors of impact to the industry. Presentations and discussions were carried out on such topics as room-and low-temperature synthesis, low-energy processing, aqueous synthesis and processing, the reuse and recycling of waste materials, and the elimination of such hazardous materials as cadmium, mercury, lead, and six-valence chromium, which are restricted from use on electronic components and automobile parts under the European Committee RoHS guidelines. The ceramic and glass industries have

Synthesis of TiO2−xNy/Ag‐PbMoO4 Composite and Their Photocatalytic Activity Under Simulated Solar Light Irradiation

“…3,4 Since the discovery of photoinduced water splitting on TiO 2 electrode by Honda and Fujishima, 5,6 TiO 2 photocatalyst has gained attention for converting light energy to reliable chemical energy [7][8][9][10] and has been widely investigated for the removal of toxic agents in air and water. 11,12 However, TiO 2 photocatalysts have low utilization efficiency of solar light due to its wide bandgap energy of ca. 3.2 eV, which covers less than 5% of the solar spectrum.…”

Influence of Cd/S ratio on photocatalytic activity of high‐vacuum‐annealed CdS–TiO2 thin film

“…1 Introduction TiO 2 is the most widely used photocatalyst for effective decomposition of organic compounds in air and water [1][2][3]. However, its technological application seems to be limited by the need of using an ultraviolet (UV) excitation source.…”
