Touching the surface: Well-defined TaON and Ta3N5 nanoparticles were fabricated by a SiO2-surface-assisted urea method, in which silica catalyzes CNx formation from urea. Such controlled nitridation endows the nanoparticles with improved activity and tunable selectivity for alkene epoxidation because of the increased electron density around Ta and surface basicity.
