Im synthesising TiO2/ZnO heterojunction photocatalyst. My synthesis is via sol gel method and after drying and then calcination i crushed my nanocomposites. So my question does crushing nanocomposites change its morphology and the heterojunction is affected?
Nur Muhammad Tharjuddin Yes, grinding nanocomposites after calcination can change its crystallinity and heterojunction, and the extent of these changes depends on the specific parameters (Crystalinity+Heterojunction) of your synthesis and grinding process.
To optimize grinding parameters, optimize time, intensity, and media type to minimize crystal amorphization. Use techniques like XRD, SEM, and TEM to characterize the ground material. Evaluate the impact of grinding on the photocatalytic performance of TiO2/ZnO nanocomposites under light conditions and target pollutants.
@Alvena Shahid so does it will effect the effectiveness of the photocatalyst? Because mine does not seem to degrade methylene blue dye
