Abstract
A monolithic metal-organic framework (MOF) composite body is disclosed, comprising: MOF crystallites adhered to each other via a binder comprising MOF; and at least 0.15 vol % nanoparticles encapsulated in the MOF body. The nanoparticles have an average particle size corresponding to an average particle diameter in the range 3-200 nm. The nanoparticles may have photocatalytic activity. The MOF composite body is of use for treating water containing an organic dye, the photocatalytic reaction supported by the photocatalytic nanoparticles being a degradation reaction of the organic dye.
Claims8
A process for manufacturing a monolithic metal-organic framework (MOF) composite body, the process comprising the steps:
- providing MOF precursors;
- providing nanoparticles having an average particle size corresponding to an average particle diameter in the range 3-200 nm;
- providing at least one solvent;
- allowing the reaction of the MOF precursors in the solvent in the presence of the nanoparticles;
- carrying out a drying stage with a maximum temperature in the drying stage of not more than 80° C. to form a monolithic MOF composite body having a smallest dimension of at least 1 mm, the MOF composite body comprising MOF crystallites adhered to each other via a binder comprising MOF, and incorporating at least 0.15 vol % and at most 1 vol % of the nanoparticles encapsulated in MOF.
