aerobic oxidative dehydrogenation of N-heterocycles were examined in detail. Many tetrahydroquinoline derivatives and a broad range of other N-heterocycles could be tolerated by the catalytic system using a biomass-derived solvent as a reaction medium. Newly generated mixed crystal phases, noticeably enhanced surface areas and labile lattice oxygen of the OMS-2-based nanocomposite catalysts might contribute
首次制备了掺有钨的基于OMS-2的纳米复合材料,并详细研究了它们在N杂环的好氧氧化脱氢中的显着增强的催化活性和可回收性。使用生物质衍生的溶剂作为反应介质的催化体系可以耐受许多四氢喹啉衍生物和各种其他N-杂环。OMS-2基纳米复合催化剂的新生成的混合晶体相,显着增加的表面积和不稳定的晶格氧可能有助于其出色的催化性能。此外,进行了广泛的动力学研究,得出的结论是1,2,3,4-四氢喹啉的脱氢是一级反应,表观活化能为29.66 kJ mol -1。
