Supported Lewis acid catalysts for the selective depolymerization of polysiloxanes
Heyuan Song, Kunyao Zhang, Zhaoxiong Tian, Fanyu Zhao, Shuangtai LeiSupported Lewis acid catalysts (InCl 3 @TiO 2 , InCl 3 @Al 2 O 3 , ZnCl 2 @TiO 2 ) were developed for polysiloxane depolymerization. InCl 3 @TiO 2 showed 65.2% conversion and 98.8% selectivity, with strong stability and recyclability, enabling efficient upcycling of silicone waste.
