Review on Modified TiO2 Photocatalysis under UV/Visible Light: Selected Results and Related Mechanisms on Interfacial Charge Carrier Transfer Dynamics
S. Girish Kumar,L. Gomathi Devi +1 more
TL;DR: This review encompasses several advancements made in these aspects of titania, and also some of the new physical insights related to the charge transfer events like charge carrier generation, trapping, detrapping, and their transfer to surface are discussed for each strategy of the modified titania to support the conclusions derived.
Journal ArticleDOI
Zinc oxide based photocatalysis: tailoring surface-bulk structure and related interfacial charge carrier dynamics for better environmental applications
TL;DR: In this article, the performance of zinc oxide (ZnO) has been improved by tailoring its surface-bulk structure and altering its photogenerated charge transfer pathways with an intention to inhibit the surfacebulk charge carrier recombination.
Journal ArticleDOI
Comparison of modification strategies towards enhanced charge carrier separation and photocatalytic degradation activity of metal oxide semiconductors (TiO2, WO3 and ZnO)
TL;DR: In this article, a review of the surface-bulk electronic structure of metal oxide semiconductors (TiO2, WO3 and ZnO) is presented.
Journal ArticleDOI
Photo degradation of Methyl Orange an azo dye by Advanced Fenton Process using zero valent metallic iron: Influence of various reaction parameters and its degradation mechanism
TL;DR: The result suggests that complete degradation of the dye was achieved in the presence of oxidizing agent when the system was amended with iron powder under UV light illumination, and probable degradation mechanism has been proposed.
