(Especially for CuO, Al2O3, TiO2, ZnO nanoparticles of 99.9% purity)
to have this information you can visit the websites of chemicals sellers and find the prices, or if not present, ask a quotation
Thank you very much for your quick response. Marcella Bini . I got it.
The typical cost of commercial NPs is:
CuO [30-50 nm, >99%] - 115,23 $ / 100 g (https://www.ottokemi.com/oxide-nanoparticles/copper-oxide-nanopowder-aps-3050nm-99-co-140.aspx)
Al2O3 [3-5 nm] - 101,46 $ / 100 g (https://nanomaterialpowder.com/nano/aluminum-oxide-nanoparticle-gamma-al2o3-5-nm/)
TiO2 [15 nm, 99%] - 72 $ / 100 g (https://www.mknano.com/Nanoparticles/Single-Element-Oxides/Titanium-Oxide-Nanopowder/TiO2-Anatase-15-nm-99-Pure)
ZnO [~30nm, >99,9%] - 79,80 $ (http://www.srlchem.com/products/compound/Zinc-Oxide-Nanopowder--Type-I-/91148)
In parentheses, I give sources of information for June 2023.
Price differ from company to company. You might have to go online.
