Strategies for the Control of Porosity around Organic Active Sites in Inorganic Matrices,homogeneous catalysts, in heterogeneous catalysts both the structure of the active site and the porosity around the active site are of extreme importance, since reactant and product diffusion can strongly influence catalytic function. Here, strategies for the control of porosity around organic active sites in silica hosts are discussed.作者: Campaign 時間: 2025-3-23 09:10 作者: Apoptosis 時間: 2025-3-23 11:05
Design of Chiral Hybrid Organic-Inorganic Mesoporous Materials as Enantioselective Epoxidation and tion reactions. This design is based on control of the different modification steps in order to improve both catalytic dispersion and mineral surface coverage.
