Unoccupied surface state induced by ozone and ammonia on H-terminated diamond electrodes for photocatalytic ammonia synthesis

Autor: Jason Bandy, Robert J. Hamers, Idris Boukahil, F. J. Himpsel, Phillip S. Johnson, Ruimin Qiao

Publikováno v: Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films. 35:04D102

This work follows upon the recent demonstration of the photocatalytic conversion of N2 to NH3 in aqueous solutions via H-terminated, polycrystalline diamond electrodes. X-ray absorption spectroscopy serves as an atom- and bond-specific probe of the l
