摘要:
Biocidal roofing granules are prepared by providing a mineral core and at least one biocidal photocatalytic metal oxide. A gel-forming inorganic coating medium is prepared and used to coat the mineral core to form a coating layer having a porous network on the mineral core, and the at least one biocidal photocatalytic metal oxide is disposed in the porous network.
