Abstract.  Photocatalytic xCaCu3Ti4O12(100x)TeO2 (x=0.25  mol% to 3 mol%), glass nanocomposites were fabricated and investigated for wastewater treatment, self-cleaning surfaces, and photocatalytic hydrogen evolution. Visible light active crystals of Cu-doped TiO2 and TiTe3O8 were grown by optimized crystallization of as-quenched glasses. The visible light photocatalytic activity of glass samples was investigated for estrogenic pharmaceutical pollutants, and the degradation rate was obtained as 168.56  min1m2. A higher photocatalytic H2 production rate was observed (135  μmoleh1g1) for the crystallized CaCu3Ti4O12-TeO2 (x=3.0) glass plate under visible light. The self-cleaning performance was observed using contact angle measurements for water under dark and light conditions. These visible light active glass ceramics are a cost effective sustainable solution for water treatment and self-cleaning applications.
