Abstract
Here, we report our findings related to the structural and photocatalytic considerations that influence the speed of electron-hole separation in semiconductor photocatalysis in the presence of reduced graphene oxide. A comparison of the exterior properties required for the degradation of the dye methylene blue and drug amoxicillin (C16H19N3O5S) as a probe by the synthesized photocatalyst reduced graphene oxide (rGO)/TiO2 nanowire with graphene oxide and reduced graphene oxide; TiO2 alone reveals that TiO2 is significantly influenced by three factors: (1) rGO interactions with TiO2 in terms of electron and hole transfer, (2) mode of reduction strategies adopted for reducing graphene oxide, and (3) production of OH• by the catalyst used. This work provides a thorough insight into the smooth, encouraging, and environment-friendly way developed for synthesizing reduced graphene oxide (rGO). The indigo dye-stimulated visible-light reduction methodology not only gives us an easy light-assisted reduction technique but also leads to new ways to get photoactive carbon-based titania semiconductor nanocomposites. Inspired by advances taking place in materials science as well as nanotechnology, we sought to develop improved photocatalytic materials by modifications to anatase TiO2 through which opportunities to improve the performance of photocatalytic pollutant treatment may emerge.
