Abstract
A copper oxide with a hollow porous structure, a preparation method therefor, and a use thereof are provided. The copper oxide with a hollow porous structure is of a hollow octahedral structure, and has a size of 200-400 nm and a specific surface area of 23.5-79.6 m2/g, where the surface of the octahedron is composed of copper oxide nanoparticles having a size of 14-33 nm, and pore structures are formed among the copper oxide nanoparticles. The copper oxide with the hollow porous structure has good conductivity, high hydrophilicity and good catalytic performance, can substantially reduce the detection potential and greatly improve the detection sensitivity and the anti-interference performance when used for the electrochemical detection of pesticides.
