Abstract: The core-shell hybrid microsphere (PW-HPW/PNIPAM),loaded with hexadecyltrimethylammonium-peroxotungstophosphate (PW-HPW) complexes,were synthesized with N-isopropyl acrylamide (PNIPAM) polymer hydrogels as support. The PW-HPW/PNIPAM composite microspheres contained PNIPAM core and PW-HPW shell with catalytic performance. The composite microspheres were used in oxidation of dibenzothiophene (DBT) with hydrogen peroxide. The microspheres showed high catalytic performance and conversion rate of DBT was more than 90.32% after 8h at 40℃. The hybrid microspheres could be easily recycled and reused for at least three times.

Key words: support, hybrid microsphere, catalyst, oxidation, desulfurization, environment

摘要: N-异丙基丙烯酰胺(PNIPAM)高聚物微凝胶为载体,利用外源沉积法制备表面担载有过氧磷钨杂多酸季胺盐(PW-HPW)的杂化微球(PW-HPW/PNIPAM).该杂化微球具有明显的核-壳结构,内部为PNIPAM水凝胶,表面均匀覆盖具有催化活性的过氧磷钨酸季胺盐.以过氧化氢为氧化剂,主要以二苯并噻吩(DBT)为模拟硫化物,研究了该杂化微球在催化氧化脱硫方面的催化性能.结果表明,杂化微球具有较高的催化活性,最佳条件下,40℃下反应8h,DBT转化率达到了90.32%.与过氧磷钨杂多酸季胺盐相比,担载后的杂化微球便于从体系中分离,经简单处理后可再次循环使用达3次以上.
