Heterogeneous and efficient transesterification of Jatropha curcas L. seed oil to produce biodiesel catalysed by nano-sized SO₄ ^2-/TiO₂.

ABSTRACT: 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 (SO₄ ^2-/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 was investigated under various operating conditions. The results reveal that both the Brønsted and Lewis acid sites are presented in the SO₄ ^2-
