Laser induced plant leaf extract mediated synthesis of CuO nanoparticles and its photocatalytic activity

Cu(ii)-assisted self-assembly of dicyandiamide-derived carbon dots: construction inspired from chemical evolution and its H2O2 sensing application

“…When the carbonization temperature was higher than 400 °C, diffraction peaks of DCD-CDs/Cu-400 were observed at 35.3°, 38.4°and 48.4°, and were attributed to diffraction on the (002), ( 111) and (−202) crystal planes, respectively, which are in close agreement with that of pure CuO and standard JCPDS values (PDF#44-0706) of monoclinic CuO NPs. 34,35 Interestingly, the XRD patterns of DCD-CDs/Cu-300 possess the characteristics between amorphous and crystal nature of CuO. Only two diffraction peaks at 35.3°and 38.4°c an be observed.…”

Green Synthesis of CuO-TiO2 Nanoparticles for the Degradation of Organic Pollutants: Physical, Optical and Electrochemical Properties

“…Various metal oxides such as ZnO, CuO, NiO, TiO2, etc., are highly explored but nanosized transition metal oxides, such as copper oxide (CuO) and titanium oxide (TiO2), have attracted scientific interest due to their potential applications in medicine, sensing, catalysis, etc. [22,24,26]. CuO has gained much attention among transition metal oxides because of its intriguing photochemical and photomagnetic capabilities [26].…”

“…[22,24,26]. CuO has gained much attention among transition metal oxides because of its intriguing photochemical and photomagnetic capabilities [26]. It is a photoconductive p-type semiconductor with a narrow bandgap (1.2 eV) and has been used in a variety of applications in gas sensing, catalysis, super capacitors, and field emission, to name a few [24,27].…”

“…However, metal doping of TiO 2 has a low thermal stability and is prone to photo corrosion [25]. CuO has been frequently employed to enhance the photocatalytic properties of TiO 2 [25][26][27]. This is because it can reduce the photogenerated electrons and holes from recombining while simultaneously lowering the energy of the band gap [24][25][26][27][28].…”

“…CuO has been frequently employed to enhance the photocatalytic properties of TiO 2 [25][26][27]. This is because it can reduce the photogenerated electrons and holes from recombining while simultaneously lowering the energy of the band gap [24][25][26][27][28]. The disadvantage with the synthesis of such CuO-TiO 2 nanocomposite, is the use of harmful chemicals.…”
