제목 Nanoporous hybrid film as porous inorganic platform for highly stable heterogeneous catalyst
초록 Nanoporous hybrid film (NHF) was synthesized by mixing with urea network based polymer sol and organosilane precursor. Phase separation behavior of polymer and inorganic sol leads to nanoporous polymer film with thin organosilica layer on pore wall. High thermal and chemical stability of hybrid film are beneficial to post impregnation process for preparation of functional structures. In this work, novel porous SiO2/Pd/TiO2 heterostructure was developed by impregnating Pd and TiO2 precursor in sequence and the catalytic activity of ntiroarene hydrogenation was evaluated with UV spectroscopy. Porous SiO2 layer greatly improved the catalytic recyclability with comparable catalytic activity
