| 摘 要： | 在微乳液体系中成功地将花瓣状介孔氧化硅微球(KCC-1)包覆在钛硅分子筛TS-1表面, 得到了一种新型微孔/介孔复合核壳结构材料TS-1@KCC-1. 详细考察了TS-1@KCC-1的合成条件及可能的形成机理. 适宜的合成温度及时间分别为373-393 K和4 h. 壳层厚度可方便地通过改变硅源正硅酸乙酯和TS-1的比例在25-80 nmm间进行调控. 以TS-1@KCC-1为载体负载Rh(OH)x后即得到双功能催化材料Rh(OH)x/TS-1@KCC-1, 该材料同时具有Ti和Rh(OH)x活性中心, 可以高效催化醛、氨水和过氧化氢经一锅串联反应直接制备得到伯酰胺.

| Abstract: | A new microporous/mesoporous composite with a core-shell structure, TS-1@KCC-1, was fabricated in a microemulsion system by coating flower-like mesoporous silica (KCC-1) on the crystal surface of TS-1 zeolite. The synthesis conditions and a possible formation mechanism were studied in detail for the TS-1@KCC-1 material. A suitable temperature and assembly time were found to be 373-393 K and 4 h, respectively. The shell thickness of TS-1@KCC-1 was conveniently tuned in the range 25-80 nm. Rh(OH)x species were supported on TS-1@KCC-1, giving rise to a novel bifunctional tandem catalyst Rh(OH)x/TS-1@KCC-1, which effectively catalyzed the one-pot synthesis of primary amides directly from aldehydes, ammonia, and hydrogen peroxide. |
