Preparation and characterization of copper-doped anatase TiO2 nanoparticles with visible light photocatalytic antibacterial activity

A review of solar and visible light active TiO2 photocatalysis for treating bacteria, cyanotoxins and contaminants of emerging concern

“…Here we discuss recent publications in the field which utilise visible light responsive titanium dioxide in order to make it a viable route for applications in industries such as environmental, hospital and wastewater treatment. Several different doping systems including nitrogen [176], nitrogen-silver [72,177], nitrogen-copper [47], sulphur [178], carbon [64], nickel [179], copper [179] and more recently graphene nano-sheet [180] doped TiO 2 (the term doping is loosely used here for addition, decoration, doping, incorporation etc.) have been prepared and analysed for their inactivation of various bacteria strains such as Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Salmonella typhimurium, and Micrococcus lylae.…”

Cu/TiO2 thin films prepared by reactive RF magnetron sputtering

“…It has been observed that TiO 2 films doped with copper [11][12][13], iron [14,15], chromium [16,17], carbon [18,19], nitrogen [20,21] and bismuth [22] improve their properties as photocatalysts in the visible region. However, the antibacterial properties of TiO 2 not only depend on dopants but also other parameters such as crystalline nature, crystalline size, phase composition, chemical composition and synthesis methodology [23]. In this regard, Cu/TiO 2 thin film shows enhanced antibacterial activity without decreasing its biocompatibility and it is also known to be a non-hazardous.…”

Enhanced disinfection of Escherichia coli and bacteriophage MS2 in water using a copper and silver loaded titanium dioxide nanowire membrane

“…The optimal copper to TiO 2 atomic ratio was selected as 3%, which is the optimum ratio identified by the prior research [23]. The solution was shaken on an orbital shaker (IKA ® Works, Inc., NC, USA) for 16 h and the copper loaded membranes were prepared using the same method for the TiO 2 membrane preparation.…”
