Highly photocatalytic glass ceramics containing MgTi4(PO4)6 crystals

• Bulk glass ceramics containing MgTi4(PO4)6 crystals were prepared.
• The glass ceramics exhibit highly photocatalytic activities.
• The photocatalytic activities of the glass ceramics are comparable with those of the TiO2-coated photocatalyst.

Glass ceramics containing Nasicon-type crystal MgTi4(PO4)6 were prepared by heat-treating MgO–TiO2–P2O5–SiO2 glasses, and their photocatalytic activities were evaluated by the decomposition of methylene blue (MB) and acetaldehyde, and measuring the water contact angle under UV irradiation. Highly photocatalytic oxidization ability and super-hydrophilicity were observed. These properties are comparable with those of the TiO2-coated photocatalyst.
