| description | The ceramic molded body e.g. roofing tile, brick, clinker and/or facade panel, made of oxide-ceramic base material with capillary structure, comprises a transparent air-cleaning surface coating, which comprises peptized photocatalytic-active particles (1) and/or photocatalytic-active particles, which are surrounded by a layer from peptized particles. The peptized photocatalytic active particles and/or photocatalytic active particles are formed as primary aggregates. The photocatalytic active particles comprise a band-gap of 3.0-3.5 eV and are producible by a sulfate pulping method. The ceramic molded body e.g. roofing tile, brick, clinker and/or facade panel, made of oxide-ceramic base material with capillary structure, comprises a transparent air-cleaning surface coating, which comprises peptized photocatalytic-active particles (1) and/or photocatalytic-active particles, which are surrounded by a layer from peptized particles. The peptized photocatalytic active particles and/or photocatalytic active particles are formed as primary aggregates. The photocatalytic active particles comprise a band-gap of 3.0-3.5 eV and are producible by a sulfate pulping method. The surface coating further comprises peptized non-photocatalytic active particles, non-photocatalytic active particles (3), which are surrounded by a layer from peptized particles and/or non-peptized non-photocatalytic active particles. The photocatalytic active particles and the non-photocatalytic active particles measured without peptization comprise average particle size of 2-20 nm and 10-15 nm respectively. A peptide layer (2) having a thickness of 1-2 nm is arranged on the non photocatalytic active peptized particles and/or on the photo-catalytic-active peptized particles. The surface coating comprises titanium dioxide-particle, which is surrounded by a completely or partially closed layer from peptized aluminum oxide-particle and/or peptized titanium dioxide-particle. Metatitanic acid-containing layer (4) is arranged between the titanium dioxide-particle and the closed layer and/or between the titanium dioxide-particle and the peptide layer. The titanium dioxide-particle, the metatitanic acid-containing layer and the closed layer form the primary aggregate with an average particle size of 35-45 nm. The surface coating has an average particle size of 2-5 nm and a thickness of 20-200 nm, and comprises an organic or inorganic bonding agent. The weight ratio of bonding agent to the photocatalytic-a |
