Fabrication of a novel catalyst support with hierarchical pore structure
(0) A novel catalyst support with trimodal pore structure was hydrothermally synthesized by building up nanoparticles of titanium silicalite-1 inside the macroporous system of silica gel using the tetrapropylammonium hydroxide (TPAOH) as template, titanium (IV) tetrabutoxide monomer (TBOT) as titanium source and the silica gel with macropores as in situ silicon source as well as matrices. The prepared support exhibited intrinsic pore of TS-1, intercrystalline mesopores and residual macropores of silica gel, accomplishing the interconnection of micro-, meso-, and macrpores.
