Industrial pollution is the major source of global air, water and soil pollution and refers to all pollution which can directly or indirectly, be linked with industry. Due to the extensive use of dyes in industries, it has become an integral part of industrial effluent. The potential toxicity of dyes and their visibility in surface water, removal or degradation of dyes has been a matter of considerable interest. Conventional purification methods are inefficient. Hence, semiconductor assisted photocatalysis has been widely employed to treat the effluent. The present investigation has been...

Global warming, the most threatening problem to be solved by the scientists to meet the Kyoto Protocol of the United Nations Framework Convention on Climate Change and to conserve the rapidly exhausting fuel reserves, stimulated the current research towards artificial photosynthesis. It is an undeniable fact that carbon dioxide accounts for the largest share of the world s greenhouse gas emissions by its alarming increase in the atmosphere. From this standpoint, the development methods to convert carbon dioxide to more useful organic compounds inexpensively is highly desirable. Photocatalytic...
