Abstract

Bismuth-based semiconductors are promising materials as visible light responsive photocatalysts due to their suitable band gaps, well-dispersed valence bands, commercial availabilities at reasonable costs, and the possibility of preparing them under mild conditions. Recent work on the preparation, characterization and activity testing of Bismuth-based photo active nanomaterials as well as associated photo reactor designs are introduced herein. In order to enhance the photocatalytic activities of the new materials, different precursors, additives, preparation procedures and process parameters, and surface treatments were tried to obtain binary and ternary heterostructures, with different doping, surface modification, nano-particle size and morphology. Application potentials of selected highly-active new catalysts were evaluated by examining the kinetics of photocatalytic degradations in compatible reactor designs. Suggestions were made for further work in the area.
