Interest in mesoporous materials (IUPAC definition: pore size 2–50 nm) has developed dramatically over the last few years, not least because the pore structure of these materials provides an extremely large surface area within a relatively small volume of material. This makes the materials suitable, for example, for catalysis, chemical sensors, and molecular separation.
The following is a selection of recent articles in this field from Angewandte Chemie, Chemistry—A European Journal, Advanced Materials, Advanced Functional Materials, and the European Journal of Inorganic Chemistry.
Density functional theory calculations are reported on a promising paradigm for adsorption of multiple hydrogen molecules to a single open metal site attached to a metal–organic framework linker via a catechol or thiocatechol. Some of these materials are predicted to have usable capacities close to the Department of Energy 2020 target of 40 gr L−1 marking them as important synthetic targets.
