Abstract

The invention provides a nickel-copper-selenium ternary nano-catalytic material with a sea urchin-like hollow structure and its preparation method and application. In the invention, copper nitrate trihydrate and nickel nitrate hexahydrate are dissolved in a mixed solvent of ethylene glycol and water, and then added Urea and polyvinylpyrrolidone react hydrothermally to form a hollow sea urchin-like precursor structure. Disperse the precursor in deionized water, add the sodium hydrogen selenide solution dropwise into the precursor dispersion, use the precursor as a template, and perform hydrothermal reaction to obtain a nickel-copper-selenide ternary nanocatalytic material with a sea urchin-like hollow structure . Compared with the prior art, the present invention successfully prepared the sea urchin-shaped hollow structure nickel-copper-selenium ternary nanomaterial for the first time through mild reaction conditions and a simple and easy-to-promote method. The sea urchin-shaped nickel-copper-selenide ternary The nanometer material can catalyze the hydrogenation reaction of p-nitrophenol, p-nitrostyrene and p-nitroaniline, and the material has good catalytic hydrogenation performance.

Description
