manufacture example 1

[0088] Manufacturing example 1: Preparation of PCP complex

[0089] In a 3000ml pear-shaped flask, add 2000ml of DMF-ethanol-water (1:1:1 by volume) and Ni(NO 3 ) 2 ·6H 2 O (23.8g), 2,5-dihydroxyterephthalic acid (H 4 dhtp, 4.8g), stirred and reacted at 100°C for 5 days. The precipitated three-dimensional structure metal complex (Ni 2 (dhtp)) was recovered by suction filtration, and washed with methanol and water. Then, dry under reduced pressure at 25°C for 24 hours to obtain the target metal complex (Ni 2 (dhtp)) 12g. Obtainment of the target metal complex was confirmed by powder X-ray structural analysis. Hereinafter, the obtained metal complex may be referred to as "Ni-MOF-74".

[0090] Manufacturing example 2: Preparation of PCP complex

[0091] In a 300ml pear-shaped flask, add 200ml of DMF-ethanol-water (1:1:1 by volume) as a solvent, Co(NO 3 ) 2 ·6H 2 O (2.4g), 2,5-dihydroxyterephthalic acid (H 4 dhtp, 0.5 g), stirred at 100° C. for 5 days, and made to react. The precipitated three-dimensional structure metal complex (Co 2 (dhtp)) was recovered by suction filtration, and washed with methanol and water. Next, drying was performed at 25° C. under reduced pressure for 24 hours to obtain 0.8 g of the target metal complex (Co2(dhtp)). Obtainment of the target metal complex was confirmed by powder X-ray structural analysis.

Abstract

The present invention provides a metal nanoparticle complex characterized by having such a structure that metal nanoparticles are dispersed in an organic structure, wherein the organic structure comprises a structure of a porous coordination polymer (PCP) containing both a metal and a polyvalent ligand capable of reducing the metal or a structure of a metal-organic framework (MOF) and carbon.

Description

technical field [0001] The invention relates to a metal nanoparticle complex and a manufacturing method thereof. [0002] In addition, in this specification, the collective term of MOF and PCP may be described as "PCP". Background technique [0003] Many PCP / metal nanoparticle complexes have been developed so far, but in order to effectively realize the reaction of the complex, a complex in which metal nanoparticles are directly connected inside PCP is required. In addition, from the viewpoint of the production cost of the composite, a method for producing the PCP / metal nanoparticle composite simply and reliably is required. [0004] In order to produce PCP / metal nanoparticles, the following methods are adopted: synthesize metal nanoparticles, coat them with PCP, or synthesize metal nanoparticles inside (or outside) the synthesized PCP, and embed metal nanoparticles in PCP . [0005] According to Non-Patent Document 1, in order to composite metal nanoparticles after prefa...
