Au nanocrystals decorated TiO2 nanotubes for photocatalytic nitrogen fixation into ammonia

Abstract

Nitrogen photofixation has been successfully performed on TiO₂ nanotubes decorated with Au nanocrystals which clearly outperform commercial P25 under the same conditions. Au nanocrystals increase N₂ chemisorption and promote charge separation for titania nanotubes, therefore playing pivotal roles in nitrogen photofixation reactions.
