Copper Oxide Nanoparticle-Coated Quartz Sand as a Catalyst for Degradation of an Organic Dye in Water

Oxidation of aqueous organic pollutants using a stable copper nanoparticle suspension

“…Nevertheless, commercial and synthesized powder CuO coupled with H 2 O 2 has demonstrated the ability to treat a wide range of aqueous organic contaminants such as pesticides, polycyclic aromatic hydrocarbons (PAHs), brominated flame retardants, and antibiotics . Another approach to deal with instability of Cu‐NP suspensions is to immobilize or form Cu‐NPs on substrates . This approach holds advantages, such as the avoidance of a post‐treatment separation stage of the Cu‐NPs from the treated solution.…”

N-doped nanoporous graphene decorated three-dimensional CuO nanowire network and its application to photocatalytic degradation of dyes

“…3,4 In recent years, the application of CuO in photocatalytic degradation of environmental organic pollutants has attracted extensive attention because of its low-cost and nontoxic end products. 5,6 Up to now, CuO photocatalyst with different morphologies such as nanorods, nanoplates, nanotubes, hollow microsphere, microower, nanowires have been successfully synthesized and widely investigated. 2,[7][8][9][10][11][12] However, the photocatalytic activity of CuO nanomaterials was still not satised, as the light-generated charge carriers in CuO cannot be efficiently split for the decomposing of dye molecules.…”
