Preparation and characterization of boron-doped titania nano-materials with antibacterial activity

► B/TiO2 nano-materials are prepared and doping improves particles agglomeration. ► Absorption spectrum move to visible light after doped. ► B/TiO2 nano-materials firstly applied to the fields of antibacterial materials. ► Calcined at high temperature of 900 °C, B/TiO2 has still strong antibacterial.
