“…It is reported that defects in nanomaterials act as trapping centers for photodynamically produced electrons [9]. Moreover, doping in nanomaterials leads to the formation of crystal defects which results in the enhancement of ROS generation [9,10]. In our case, Raman spectroscopy and magnetic studies confirmed the enhancement in oxygen vacancies with Fe doping.…”

“…But the main issue is the short half life of electron hole pair, which can recombine before interacting with the water and oxygen.

“…It has been reported that CeO 2 nanostructures inhibit the viability of bacteria and cancerous cells via apoptosis caused by ROS [8]. The ROS generation is believed to be dependent on level of defects in the crystal structure of nanostructures [9]. The defects chemistry and other physio-chemical properties of CeO 2 nanostructures can be tuned by different ways such as thermal annealing, ion beam irradiation and selective metal doping [10].…”

ZnxCu1−xO (where x= 0, 0.01, 0.03, 0.05, 0.07 and 0.1 mol%) hierarchical nanostructures have been prepared via soft chemical route. X-ray diffraction (XRD) results of the synthesized samples reveal the monoclinic structure of CuO without any impurity related phases. The micro-structural parameters such as crystallite size and microstrain have been strongly influenced by Zn doping. Scanning electron microscope (SEM) analyses depict the formation of hierarchical nanostructures having average particle size in the range of 26-43 nm. The surface area of CuO nanostructures has been reduced systematically with the increase in Zn content which is linked with the variations in particle size. An obvious decrease in the optical band gap energy of the synthesized CuO hierarchical nanostructures has been observed with Zn doping which is assigned to the formation of shallow levels in the band gap of CuO and combined transition from oxygen 2p states to d sates of Cu and Zn ions. The bactericidal potency of the CuO hierarchical nanostructures have been found to be enhanced remarkably with Zn doping.

By one-step hydrothermal method, pure and Ce-doped CuO nanostructures (NSs) are successfully synthesized. In this work, C 4 H 6 CuO 4 ·H 2 O and Ce(NO 3 ) 3 ·6H 2 O are used as the precursor and the dopant. The results of X-ray diffraction and energy dispersive spectroscopy demonstrate that small portions of Ce ions are incorporated into the crystal lattice of CuO NSs and substitute Cu ions with the formation of a tiny impurity (Cu 2 O). Field emission scanning electron microscopy images display that the nanoellipsoid morphology of pure CuO transforms to an apparently rough surface with larger sizes of the morphology by doping with Ce element. Compared to pure CuO NSs, the UV-vis absorption of Ce-doped CuO NSs is remarkably enhanced, which exhibits a strong ability of light absorption both in the 200-380 nm and in the visible region (380-800 nm). The measured band-gaps of pure and Ce-doped CuO NSs with different amounts of Ce ions are 2.07 and 1.93, 2.03, 2.02 eV, respectively. The photocatalytic test shows that the photocatalytic activity of Ce-doped CuO NSs is eminently better than for pure CuO NSs, with the photodegradation of methylene blue solution rising up to 90.04%.
