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 weight ratio of bonding agent to the photocatalytic-active particle is 1:1 to 1:0.6. An engobe or a glaze is arranged between the oxide-ceramic base material with capillary structure and the surface coating. The mass ratio of the photocatalytic particle to the non-photocatalytic-active particles is 3:6 to 4:6. The peptide- and/or metatitanic acid-containing layer are removed by heating at 300-600[deg] C.
