Porosity Tuning in Soft-templated Mesoporous Silica: The Influence of Block Copolymer Composition and Concentration

Macroscopic properties of mesoporous metal oxides depend on the mesopore architecture, i.e., the pore size, wall thickness, and pore connectivity. Consequently, rational preparation protocols and deep knowledge of the templating mechanism are required for systematic porosity–property studies and the...
