TiO2-based self-compacting glass mortar: Comparison of photocatalytic nitrogen oxide removal and bacteria inactivation

► TiO2-architectural mortar for NO removal and Escherichia coli inactivation was investigated. ► The influence of nano-TiO2 dosage and recycled glass colour was evaluated. ► Transparent glass slightly enhanced the photocatalytic activity of NO removal. ► Photocatalysis of NO removal might not be extrapolated to antibacterial activity. ► Photocatalytic bacteria inactivation is a more complex process than NO removal.
