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.

Composite metal organic framework materials, processes for their manufacture and uses thereof

[Problem] The present invention provides a NOpurification catalyst which utilizes Ag as one of the catalyst components and exhibits NOpurification performance without adjustment to a special exhaust gas composition, as well as a method of producing the same. [Means for Solution] The present invention provides a nitrogen oxide purification catalyst in which particulates are supported on a metal oxide carrier, wherein the aforementioned particulates consist of Ag and Ni and the aforementioned Ag and Ni are at least partially alloyed. Also provided is a method of producing the aforementioned catalyst, comprising the step of preparing a colloidal suspension in which the ratio of Ag is 10 to 90 at % with respect to the total amount of Ag and Ni.
