Abstract
The present invention provides a supported nanometer compound oxide environmental purification material and the preparation thereof, the diatomite and the zeolite are employed as carrier to load one of nanometer TiO2, nanometer ZnO and nanometer CeO2. The preparation method comprises preparing carriers by diatomite and zeolite; preparing compound oxide precursory sol by employing ethanol as medium and the zinc nitrate and/or cerium nitrate and butyl titanate as material; loading the compound oxid precursory sol on the carrier to obtain loading-body; drying, baking and cooling the loading-body to obtain the supported nanometer compound oxide environmental purification material of the present invention which has perfect filter, adsorption, ion exchange, catalytic degradation and antibacterial function, good chemical stability, convenient usage, reclaim and regeneration, safety, innocuity, simple preparation technique and low cost. The supported nanometer compound oxid environmental purification material of the present invention is suitable for batch production and used widely in purifying process of atmosphere and water system.
