Abstract:
The rapid recombination rate of photoexcited carriers for iron titanate (FeTiO3) is still limited the process performance of photo-Fenton. This article reports the successful synthesis of the highly efficient Z-scheme FeTiO3/MOF-derived In2S3 photocatalyst using the hydrothermal method, compensating for the susceptibility of FeTiO3 photo-generated carriers to complexation to a certain extent. A series of characterization have been carried out to explore the structure, morphology and composition of FeTiO3/MOF-derived In2S3 heterostructure. The 0.5 FeTiO3/MOF-derived In2S3 exhibits the excellent photo-Fenton performance for TCH, Cr6+ and OTC, the degradation rate constants (k(2)) are up to 0.6297 Lmg(-1)min(-1), 1.332 Lmg(-1)min(-1), and 0.427 Lmg(-1)min(-1), respectively. Active species capture experiments and electron paramagnetic resonance (EPR) spectra show that photo-generated holes (h(+)) and superoxide radicals (O-2(-)) are present in the photo-Fenton system. The superior photo-Fenton performance is mainly manifested in the following: the MOF-derived In2S3 micro-floral carrier extends the reaction interface of 0.5 FM-I; FeTiO3 effectively enhances the photo-absorption ability of 0.5 FM-I in visible range; the construction of Z-scheme FeTiO3/MOF-derived In2S3, forming the new carriers transport channels and enhancing the generation of O-2(-) and OH. This experimental exploration provided a reasonable experimental basis for the preparation of efficient photocatalysts.
