About this collection
We delighted to present a cross-journal web collection on porous materials in conjunction with the 6th International FEZA (Federation of European Zeolite Associations) Conference on the theme “Porous Systems: From Novel Materials to Sustainable Solutions.”
Guest edited by FEZA 2014 Co-Chair, Prof Dr Roger Gläser (Universität Leipzig), and published across several Royal Society of Chemistry publications – Physical Chemistry Chemical Physics (PCCP), Catalysis Science & Technology, Dalton Transactions, Journal of Materials Chemistry A, Journal of Materials Chemistry B, andRSC Advances – the collection covers all aspects of science and technology associated with ordered porous materials: zeolites, zeotypes, mesostructured materials and porous coordination polymers.
New articles will be added to the collection as soon as they are published.
