Developing high-efficiency hetero-catalysts for transesterification reaction is of great importance in the production of biodiesel from Jatropha curcas L. seed oil (JO). Here, we synthesized a series of sulfated TiO2 by treating with varying H2SO4 concentration (xSO42-/TiO2) and TiO2 catalysts and applied to the transesterification of JO. Furthermore, these heterostructures were characterized by many characterization methods including XRD, FT–IR, N2–adsorption, SEM, TEM, TG, py-IR and NH3-TPD, and their catalytic performance were investigated under various operating conditions. The results reveal that both the Brønsted and Lewis acid sites are presented in the xSO42-/TiO2 catalysts, while only Lewis-type sites are observed in the TiO2 catalyst. And the acid intensity, surface area and mesoporous volume of catalysts are improved obviously after treating with sulfuric acid of TiO2. Then the xSO42-/TiO2 catalysts exhibit much higher catalytic activity than TiO2 catalyst, which is attributed to the larger surface area and mesoporous volume and stronger acidity. Furthermore, the reusability behavior of 1.5SO42-/TiO2 catalyst in transesterification of JO was also studied.
