Abstract

The invention provides a sea urchin shaped hollow structure nickel, copper and selenium ternary nanometer catalytic material and a preparation method and application thereof. Copper nitrate trihydrateand nickel nitrate hexahydrate are dissolved into a mixing solvent of ethylene glycol and water, urea and polyvinylpyrrolidone are added, a hydrothermal reaction is performed, and the hollow sea urchin shaped precursor structure is formed; the precursor is dispersed into deionized water, a sodium hydrogen selenide solution is added into the precursor dispersing solution drowse, the precursor is adopted as a template, the hydrothermal reaction is performed, and the sea urchin shaped hollow structure nickel, copper and selenium ternary nanometer catalytic material is obtained. Compared with theprior art, the sea urchin shaped hollow structure nickel, copper and selenium ternary nanometer catalytic material is successfully prepared for the first time through the method which is mild in reaction condition and simple and easy to popularize, the prepared sea urchin shaped hollow structure nickel, copper and selenium ternary nanometer catalytic material can catalyze a hydrogenation reactionof p-nitrophenol, p-nitro-styrene and paranitroaniline, and the material has the good catalytic hydrogenation performance.

Description

technical field [0001] The invention belongs to the technical field of new material preparation, and relates to a preparation method and application field of micro-nano materials, in particular to a nickel-copper-selenide ternary nano-catalysis material with a sea urchin-shaped hollow structure and a preparation method and application thereof. Background technique [0002] Copper selenide is a very important metal chalcogenide compound, which is widely used in degradation dyes, light-emitting diodes, photocatalysts and electrochemical cells. In addition, copper selenide is also used in thermoelectric devices, nonlinear optics, etc. Materials, light-emitting and display devices, infrared detectors, lasers, and photothermal therapy have good application prospects. Zou Hong Yan and Huang Cheng Zhi (ACS Sustainable Chem.Eng., 2017, 5(5), pp 4154–4160) prepared dendritic copper selenide with side branches with good adsorption and photocatalytic ability. Li Can (J.Phys.Chem.C 201...
