Cu-doped TiO<inf>2</inf> nanopowder synthesized by sonochemical process

Development of copper doped titania based photoanode and its performance for dye sensitized solar cell applications

“…In Fig. 6(b) new peaks are observed at 480e529 cm À1 in powder samples annealed at certain temperatures which correspond to the stretching mode of CueO bond [40,41]. This result along with EDX spectra confirms the incorporation and doping of copper in titania lattice and its existence as CuO.…”

Preparation and Characterization of Mg/TiO2 for Visible Light Photooxidative-Extractive Deep Desulfurization

“…Since sunlight consists of less than 5% UV portion, only a small fraction of solar spectrum can be utilized. In order to harvest the visible light portion of the sun, modification by metal doping has been proven to be effective (Afshar et al 2011;Choi et al 2010;Feng et al 2013;Kudo et al 2007;Linsebigler et al 1995;Wongpisutpaisan et al 2013). In principle, the metal dopants can reduce the band gap energy and thus extend the active region of TiO 2 from UV to visible light.…”

Engineering and Economic Perspective in The Production of Cu Nano

“…Several methods such as chemical reduction [6], sonochemical reduction [7], microemulsion techniques [8], electrochemistry [9], hydrothermal [10], sol-gel synthesis [11], polyol processes [12] and microwave-assisted methods [13] is the primary technique for preparing copper nanoparticles from a bottom-up approach. Biological synthesis combines biological principles (reduction / oxidation) by microbial enzymes or plant phytochemicals with physical and chemical approaches to produce nanosize particles [14].…”
