Abstract
SummaryThe rGO/TiO2 nanocomposite photocatalyst was synthesised using the sol–gel‐irradiation way to efficiently remove deoxynivalenol (DON) for the grains product's safety and quality. With the nanosize effect of irradiation, the photocatalyst has a smaller average grain size, preventing the recombination of electrons and holes. Moreover, based on UV–Vis DRS study, rGO/TiO2 could utilise visible light and have a broader response range to light. Furthermore, to the application, the photocatalyst rGO/TiO2 with 30 KGy irradiation dosage had an 80.32 ± 4.41% photocatalytic degradation rate of DON. Compared to the photocatalyst without irradiation, there was a 9.98% increase in the degradation rate. This result provided an excellent candidate photocatalyst for the removal of DON and also promoted the development of photocatalysis applications.
