Embodiment 1

[0085] Preparation of Cu containing Cu by solvothermal method 2+ and Zn 2+ Multimetal Component Organic Framework Compound HKUST-1-CuZn Micron Crystalline Powder (Such as figure 2 shown) , use dimethylformamide to dissolve copper nitrate, zinc nitrate and trimesic acid, and heat at 85 degrees Celsius for 12 hours to obtain a blue crystal powder, which can be adjusted by changing the ratio of copper nitrate and zinc nitrate used in the synthesis. Metal ratios in HKUST-1-CuZn. After the impurities were removed by solvent washing, the solvent in the channels of HKUST-1-CuZn was removed by heating to obtain a dry HKUST-1-CuZn powder sample. X-ray powder diffraction proves that the obtained HKSUT-1-CuZn crystal powder diffraction peaks completely match their simulated diffraction peaks, scanning electron microscopy and energy dispersive X-ray analysis prove that Cu and Zn have the same distribution in the crystal, thus proving that the obtained multiple Metal-component organi...

Abstract

The invention discloses nano-alloy particles and a patterning method thereof. A smelting method of the nano-alloy particles comprises the following steps that (1.1) the surface of a substrate is evenly covered with multi-metal-component organic framework compounds to form a multi-metal-component organic framework compound layer; and (1.2) a light source is used for irradiating the multi-metal-component organic framework compound layer to prepare the nano-alloy particles deposited on the substrate. The smelting method has the advantages of low cost and high production efficiency. The nano-alloyparticles produced by the smelting method have the advantages of uniform mixing of metal elements, adjustable alloy ratio, good chemical stability in the air and the like. The patterning method has the advantages that the production cost is low, the production efficiency is high, stability of the generated nano-alloy particles is good and a pattern can be customized at will and is more suitable large-scale production for the next generation of microelectronic devices, sensors, and optoelectronic devices based on the nano-alloy particles.

Description

technical field [0001] The invention belongs to the field of nano metal particle material and device preparation thereof, and specifically refers to a nano alloy particle and a patterning method thereof. Background technique [0002] The smelting of metal and alloy materials has played a pivotal role in the development of human civilization. Most of the alloy materials prepared by traditional metallurgical processes are huge in size, counted in tons, while nano-alloy particles are a kind of metal materials in nanometer size (<200nm), due to their uniform size and specific surface area far exceeding traditional materials, in Energy, catalysis, photoelectric materials and other fields have broad application prospects. Traditional metallurgical techniques cannot produce such tiny nanoalloy particles. In the laboratory, nano-alloy particles are mainly prepared by "wet chemical" and "physical methods". In the wet chemical method, different kinds of metal salts are dissolved...
