Copper Oxide Nanoparticles
Copper (I) oxide (cuprous oxide, Cu2O) nanoparticles from nanoComposix are of interest for a variety of applications, ranging from photovoltaics to catalysis to battery electrode materials, and are candidates for nanotoxicology and antimicrobial studies. These semiconductor particles are coated with polyvinylpyrrolidone (PVP) and are available with diameters of 30 nm and 50 nm with narrow size distributions. Other sizes (up to 250 nm in diameter) or surface functionalizations are available upon request. Please contact us for additional information.

Copper oxide nanoparticles from nanoComposix have a polyvinylpyrrolidone (PVP) surface and are available in a standard size of 50 nm diameters. The particles have very good size and shape uniformity, and are provided in water at 1 mg/mL.
Cuprous oxide (Cu2O) is a p-type semiconductor with interesting excitonic features and a bulk band gap of 2.17 eV. Recently, several studies have demonstrated the potential of Cu2O for gas sensing, photodegradation of dye molecules, CO oxidation, photo-activated water splitting, as anti-bacterial material for sterilization and as electrode material for lithium ion batteries.
The optical properties of Cu2O nanoparticles are highly size-dependent, and exhibit contributions from the semiconductor absorption and light scattering from the particles.
The size, capping agent, and dispersion media of cuprous oxide (Cu2O) nanoparticles can be tuned for your application. NanoComposix has successfully manufactured monodisperse cuprous oxide (Cu2O) nanoparticles with sizes or diameters tunable from 30 nm up to 240 nm, and dried, redispersible samples are available in some instances.
