Gold nanocrystal anchored In2O3 hollow nanospheres for N2 photofixation to ammonia

Abstract

Au nanocrystal anchored In₂O₃ hollow nanospheres have been fabricated, which show good activity for N₂ photofixation into ammonia. Such peculiar hollow microstructures favor light harvesting and N₂ chemosorption, both of which are further strengthened in the presence of Au nanocrystals. Charge separation in In₂O₃ has also been improved by anchoring Au nanocrystals.
