Document Type and Number:
WIPO Patent Application WO/2018/082585
Kind Code:
A1
Abstract:
Disclosed is a synthesis method for a composite gas sensitive material of a porous zinc oxide nanosheet loaded with a high-dispersion nano precious metal. The method comprises the following steps: (1) basic zinc carbonate is immersed into a water solution of precious metal ions, stirring is conducted in the absence of light, and a reaction solution containing precipitate is obtained; and (2) the precipitate in the reaction solution obtained in step (1) is subjected to centrifugal washing, drying and calcination, and the composite gas sensitive material is obtained. The material can be used for gas sensitive sensing detection of volatile organic pollutants (VOCs and chlorobenzene gases), the gas sensitive response is good, the synthesis method for the material is green and simple and convenient, with good repeatability, and mass production and application to gas sensing detection can be easily achieved.
