AI Article Synopsis
- A novel photocatalyst, graphene oxide coupled to TiO (GO-TiO), was synthesized and characterized to evaluate its performance against the well-established TiO (P25) from Degussa.
- The characterization techniques used indicated that GO-TiO has high porosity, good charge properties, and high electron mobility, which together enhance its ability to degrade pollutants.
- Optimal reactor conditions were tested, leading to effective degradation of the model drug methylthioninium chloride and suggesting potential for catalyst reuse and competitive energy consumption during pollutant treatment.
Article Abstract
The synthesis and characterization of novel graphene oxide coupled to TiO (GO-TiO) was carried out in order to better understand the performance of this photocatalyst, when compared to well-known TiO (P25) from Degussa. Thus, its physical-chemical characterization (FTIR, XRD, N isotherms and electrochemical measurements) describes high porosity, suitable charge and high electron mobility, which enhance pollutant degradation. In addition, the importance of the reactor set up was highlighted, testing the effect of both the irradiated area and distance between lamp and bulb solution. Under optimal conditions, the model drug methylthioninium chloride (MC) was degraded and several parameters were assessed, such as the water matrix and the catalyst reutilization, a possibility given the addition of HO. The results in terms of energy consumption compete with those attained for the treatment of this model pollutant, opening a path for further research.
