Photocatalysts under visible-UV light for removal of organic dyes using dendritic fibrous nano-titanium modified with DyVO4 nanoceramic

Abstract

DyVO4 NPs in the nanospaces a fibre of dendritic fibrous nano-titanium together can lead to an unheard potent for the production of bifunctutional nanocatalyst (DFNT/DyVO4). Photocatalytic degradation of organic dyes residues is an environmentally friendly and promising approach for addressing challenges that threaten living organisms. In this study, an efficient fibrous heterojunction photocatalyst was rationally designed, fabricated, and successfully applied for removal of eosin, methyl orange, and methyl violet. The obtained results showed that the content of DyVO4 quantum dots affects the yield of degradation. Using quantum dots in the structure of the photocatalyst leads to an improvement in the capacity of light-harvesting, the efficiency of charge transfer, and the rate of electron transfer. The catalyst activity is evaluated considering different components of the catalyst for the synthesis of removal of organic dyes. The reasonable procedures were proposed according to the cooperation among the DFNT and DyVO4 groups NPs sites over the catalyst that can be recovered and then reused without any significant reactivity loss considering at least 10 consecutive turns.
