PHOTOCATALYSIS Nano TiO2

PHOTOCATALYSIS Nano TiO2 Photo-stimulated catalysis offers an attractive tool for applications in producing clean fuel and in degrading toxic pollutants for environmental cleanup. However, a specific problem associated with commonly used photo-catalysts is the large band-gap energy, which requires artificial light. Success of this technology depends on engineering of electronic bands of the catalyst for paradigm-shift to solar-based photocatalysis that could produce large economic and social benefits. Successful synthesis of chemically modified photocatalyst through band engineering enables use of sunlight for splitting water into clean hydrogen fuel, sun-powered remediation of environmental pollutants, and creation of solar-driven self-cleaning and antifogging building materials.
