concept for the preparation of an olefin metathesis catalytic membrane. This goal was achieved by grafting a Grubbs II precatalyst on a zirconia membrane generating a tailor-made Hoveyda–Grubbs precatalyst on the surface of an ultrafiltration inorganic membrane. The obtained membranes were characterized by different techniques evidencing the grafting. The catalytic activity was also evaluated in a model
摘要 本研究旨在开发一种制备烯烃复分解催化膜的创新概念。这一目标是通过在氧化锆膜上接枝 Grubbs II 预催化剂来实现的,在超滤无机膜的表面上生成定制的 Hoveyda-Grubbs 预催化剂。获得的膜通过证明接枝的不同技术表征。还在模型闭环复分解反应中评估了催化活性。据我们所知,这份手稿报告了第一个如此复杂的基于钌有机金属配合物的催化膜。尽管必须改进膜接枝以获得更好的催化活性,但实现了概念验证。
