Abstract
Disclosed embodiments concern a composition comprising a diatom frustule and two or more photocatalytic nanoparticles dispersed on the surface of the frustule. Also disclosed are embodiments of a method for making the composition. The nanoparticles are dispersed such that they are separate and not in physical contact with each other. An average distance between the nanoparticles may be from greater than 0 nm to 100 nm. The nanoparticles may comprise a dopant material. Paint compositions comprising the diatom frustule compositions are also contemplated. The diatom frustule composition may be useful for removing and/or degrading volatile organic compounds, such as those present in the atmosphere.
