Metal oxide nanoparticles, such as titanium dioxide (TiO2), zinc oxide (ZnO), and cerium oxide (CeO2), are widely used as catalysts for various chemical reactions, including photocatalysis, water ...
A zinc oxide nanoparticle has a diameter of 32 nm. The diameter of a zinc atom is 0.28 nm. Estimate how many times larger the nanoparticle is compared to a zinc atom. A cube-shaped nanoparticle ...
