SILP materials based on TiO₂-SiO₂ and TiO₂-SiO₂/lignin supports as new catalytic materials for hydrosilylation reaction - synthesis, physicochemical characterization and catalysis.

ABSTRACT: The oxide system TiO₂-SiO₂ as well as a TiO₂-SiO₂/lignin system have been obtained by the sol-gel synthesis method and applied as supports in Supported Ionic Liquid Phase (SILP) materials. In total 24 SILP systems were obtained with ionic liquids containing imidazolium, pyridinium, phosphonium or sulfonic cations and bis(trifluoromethylsulfonyl)imide or methylsulfate anions, and homogeneous complexes of rhodium or platinum as the active phase. The supports and catalytic materials were subjected to thorough characterization by elemental analysis, XRD, SEM-EDX, IR, and TGA, and their particle size distribution and porous properties were assessed. The new SILP materials were used in hydrosilylation of 1-octene with 1,1,1,3,5,5,5-heptamethyltrisiloxa
