| 摘 要：基于H2SO4溶液浸漬法改性氫氧化鈦（Ti（OH）4）和氫氧化鋯（Zr（OH）4）制備了SO42-／TiO2和SO42-／ZrO2固體超強酸催化劑。利用XRD、N2-物理吸附、FT-IR和NH3-TPD技術(shù)對催化劑的微觀(guān)結構及酸性質(zhì)進(jìn)行了表征。并將其用于麻瘋樹(shù)籽油酯交換生產(chǎn)生物柴油反應，測試其催化活性和產(chǎn)物選擇性。結果表明，硫酸改性后的催化劑表現出更高的催化活性，主要歸功于催化劑的強酸性和大比表面積促進(jìn)了酯交換反應。 |

| Abstract：Firstly, SO42-/TiO2 and SO42-/ZrO2 solid superacid catalysts were synthesized through the Ti(OH)4 and Zr(OH)4 impregnated in H2SO4 solution, respectively. Secondly, the microstructure and acid properties of the catalysts were characterized by XRD, N2 physical adsorption, FT-IR and NH3-TPD. Furthermore, the catalysts were used in the transesterification of Jatropha curcas seed oil (JO) to produce biodiesel, and its catalytic activity and biodiesel selectivity were analyzed. The results showed that the sulfated metal oxides catalysts exhibited better catalytic activity owing to the strong acidity and large specific surface area, which could promote the transesterification of JO. |
