At present, many of the catalyst carriers studied at home and abroad are: SiO2, Al2O3, glass fiber mesh (cloth), hollow ceramic ball, sea sand, layered graphite, hollow glass beads, quartz glass tube (film), ordinary (conductive) glass Plexiglass, optical fiber, natural clay, foam, resin, wood chips, expanded perlite, activated carbon and the like.
Ceramics is also a porous material, the TiO2 particles have good adhesion, acid and alkali resistance and high temperature resistance is good, can also be used as catalyst carrier. If the daily use of ceramic on the load of TiO2, can be made with a good self-cleaning function of the ceramic, play a role in the purification of the environment. HE Fei et al. Using TiO2 sol-gel method, TiO2 grain with particle size of 40 ~ 100nm was prepared on the surface of homemade ceramic enamel. It is closely integrated to form a transparent uniform "rainbow effect" of TiO2 photocatalytic film self-cleaning functional ceramics, with super-hydrophilic and decontamination function.
