Applications of Nanotechnology in the Chemical Industry
Nanoparticles have several advantages as photocatalysts. First, their small particle size and large specific surface area result in higher photocatalytic efficiency. Additionally, the electrons and holes generated by the nanoparticles are less likely to recombine before reaching the surface, allowing for a higher quantity of charge carriers (electrons and holes) to participate in chemical reactions, thus increasing the activity. Furthermore, nanoparticles often exhibit transparency when dispersed in a medium, making it easier to study charge transfer, proton transfer, and the effects of semiconductor energy levels and surface state densities using optical methods.
