The structure and morphology of the samples will be characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, nitrogen adsorption, etc. Based on this, we will study the preparation method and catalytic performance of different metal nanoparticles on the three-dimensional ordered macroporous catalyst. The performance of the catalyst will be evaluated by catalytic degradation of dye wastewater and other practical measurements.Keywords:Three-dimensional ordered macroporous materials, sol-gel method, metal nanoparticles, catalytic performance, degradation of dye wastewater.
