摘要
将钯杂多酸锚定在3-氨丙基-三乙氧基硅烷(APTS)修饰的SBA-15孔道内,得到了一种新型、高效的钯杂多酸/SBA-15(Pd3Bi2W22/SBA-15)多相催化材料.采用XRD和FT-IR红外光谱对催化剂进行了表征,并检测了其对正十六烷氧化的催化性能.结果表明,以空气为氧化剂,在无任何溶剂的条件下,该催化剂对正十六烷烃氧化成醇类和酮类显示出了优良的催化性能,并且可多次回收利用.
[Pd3(H20)gIi2W22076]8 /SBA-15 (Pd3Bi2W22/SBA-15) has been synthesized through [Pd3(H20)gBi2W22076]8 anchored on 3-aminopropyltriethoxysilane (APTS)-modified mesoporous SBA-15. The catalyst was characterized by X-ray diffraction (XRD) and Fourier transform infrared reflectance (FT-IR) spectroscopy. The results showed that the catalyst ex hibits high catalytic performance and reusaility for the solvent-free aerobic oxidation of n-hexadecane to alcohols and ke tones by usin air as the oxidant under ambient conditions.
