CuO@ZnO core-shell nanocomposites: Novel hydrothermal synthesis and enhancement in photocatalytic property

CuO/ZnO Heterojunction Nanorod Arrays Prepared by Photochemical Method with Improved UV Detecting Performance

“…Moreover, CuO has the advantage of its large abundance in nature, its low cost, its inability to pollute, and its simple synthesis like ZnO [24]. Previously, CuO/ZnO heterojunction nanostructures have been extensively studied in photocatalytic reactions [25,26,27]. The CuO of CuO/ZnO heterojunctions were often prepared by radio-frequently (RF) magnetron sputtering techniques or electrochemical deposition (ECD) [28,29,30,31].…”

Single‐ and Double‐Shelled CoFe2O4 Nanoparticles as Highly Efficient Magnetic Separable Photocatalysts

“…Figure schematically describes the possible mechanism of the formation of the core/shell/shell structured CuO@ZnO@CoFe 2 O 4 , considering the above mentioned results, other researchers’ previous reports and our recent works ,. Double coating on CoFe 2 O 4 core involves two steps, firstly, the zinc(II) ions are absorbed on the surface of initial cobalt ferrite cores through the electrostatic interactions with oxide anions presented on the surface of CoFe 2 O 4 NPs, or locates inside the small gaps on the surface of CoFe 2 O 4 NPs.…”

“…Recently, ZnO‐based core/shell nanostructures have been studied and demonstrated that a higher photocatalytic activity can be obtained . As an important p‐type narrow bandgap semiconductor, CuO has been applied to improve the photocatalytic efficiency of some wide bandgap semiconductors, so there are a lot of reports about CuO@ZnO nanocomposites, as p‐n type core/shells, presently . Unfortunately, efficient separation and recovery of nanosized ZnO‐based photocatalysts is still a challenge, which limits their widespread application.…”

Pressure and osmotically driven membrane processes: A review of the benefits and production of nano-enhanced membranes for desalination

“…Other factors during the hydrothermal process, such as the pH of the solution, were also shown to influence the shape of the NMs. Additionally, the hydrothermal method was ap-780 plied to combine ZnO and CuO NPs in core shell design structures, where CuO NPs are coated with ZnO NPs (Mansournia & Ghaderi 2017).…”
