Abstract
Nano-ZnFe2O4 photocatalysts are one-step synthesized via solution combustion route, which are characterized by XRD, TEM, and UV-vis DRS. The photocatalytic activity of these samples are evaluated by the removal of thiophene in model oil under visible light irradiation. The influences of fuel amount on the particle size and photocatalytic performance of the as-synthesized catalysts are investigated. The results show that the ZnFe2O4 with the particle size of 21.9 nm exhibits the highest photocatalytic ability, which is acquired using triethylamine hydrochloride as fuel in the fuel-rich combustion condition. The desulfurization yield of model oil can reach 92.5% in 5 h photo-irradiation and the sulfur content can be decreased from 200 ppm to 15 ppm.References
