Metal doped titania in anatase phase has been proven as a promising candidate for energy and environmental applications. in this present work, the antimicrobial efficacy of copper (cu) doped tio2. Surface contamination by microbes is a major public health concern. a damp environment is one of potential sources for microbe proliferation. smart photocatalytic coatings on building surfaces using semiconductors like titania (tio2) can effectively curb this growing threat. metal doped titania in anatase phase has been proven as a promising candidate for energy and environmental applications.
These further promoted the photocatalytic efficiency. a significantly high bacterial inactivation (99.9999%) was attained in 30 min of visible light irradiation by cu tio2 . keywords: cu doped tio2 ; doping; phase transition; escherichia coli; staphylococcus aureus; photocatalysis; antibacterial coatings 1.

Environmental applications. in this present work, the antimicrobial efficacy of copper (cu) doped tio 2 (cu tio 2) was evaluated against escherichia coli (gram negative) and staphylococcus aureus (gram positive) under visible light irradiation. doping of a minute fraction of cu (0.5 mol %) in tio 2 was carried out via sol gel technique. cu tio 2. We report a synthetic strategy for fabricating cu doped tio 2 hollow nanostructure for visible light responsive photocatalysis. hollow cu doped tio 2 photocatalysts were prepared by sol–gel coating of tio 2 on the surface of sio 2, removal of sacrificial core, cu 2 ion exchange, and calcination followed by acid leaching.

Request pdf | cu doped tio2: visible light assisted photocatalytic antimicrobial activity and high temperature anatase stability | indoor surface contamination by microbes is a major public health. The photocatalytic activity of pure and cu doped tio2 nanoparticles were investigated against degradation of reactive red 198 under visible light and the results were compared with commercial tio2. this work studies the effect of cu doping on structural, morphological, optical, dielectric and photocatalytic activity of tio2 nanoparticles.
