Study on Modification and Performance of Nano Catalyst Used for Ceramic Purification

Abstract

This paper takes the nano tungsten oxide as an example and researches the influence of modification on optical properties and catalytic performance through the doping modification in the preparation process of sol-gel. It adopts SEM spectroscopy analysis, X-ray diffraction (XRD) and UV-visible spectrophotometry methods for characterization of nano-doped tungsten oxide structure and optical absorption properties, and adopts the one-shot purification rate of formaldehyde, toluene and benzene for characterization of the purifying performance of the reforming catalyst that used to purify the ceramic material.
