摘要

采用前驱体分解法制备了丙烷选择性氧化制丙烯醛的VTeO/SBA-15催化剂。与传统浸渍法制备的催化剂相比，该催化剂表现出更好的性能。在500℃条件下，在2%的负载条件下，丙烯醛的收率为9.3%。采用XRD、n2吸附、H2-TPR、Py-IR和XPS等测试手段揭示了催化剂的结构与性能之间的关系。

Effective VTeO/SBA-15 Catalyst Prepared by Precursor Method for the Selective Oxidation of Propane to Acrolein

Precursor decomposition was used for the preparation of VTeO/SBA-15 catalyst for the selective oxidation of propane to acrolein. The catalyst shows a better performance compared with those prepared by conventional impregnant method. A yield of 9.3% of acrolein was achieved with 2% V loadings at 500 °C. XRD, N₂-adsorption, H₂-TPR, Py-IR and XPS measurements were used to unclose the relationship between the structure and performance of the catalyst.
