Nano chlorine dioxide air filter core material, preparation method, air filter core and module

The invention discloses a nano chlorine dioxide air filter core material. The nano chlorine dioxide air filter core material comprises nano zinc oxide and chlorine dioxide, and also includes a ceramicmaterial. The invention also discloses a preparation method of the nano chlorine dioxide air filter core material. The method comprises the following steps of: uniformly mixing the nano zinc oxide and the ceramic material in proportion, adding water, stirring the substances uniformly again, and preparing the uniformly stirred mixture into particles; baking or sintering the particles, and introducing high-pressure air for surface treatment to form surface micropores, thereby obtaining filter core particles; completely soaking the filter core particles in a chlorine dioxide solution; and carrying out low-temperature drying on the filter core particles soaked in the chlorine dioxide solution in a sealed cabin to obtain the nano chlorine dioxide air filter core material. The invention also correspondingly discloses a
