Dependence on chemical structure of the production of NH 4 + and/or NO 3 −3 ions during the photocatalyzed oxidation of nitrogen-containing substances at the titania/water interface

摘要: The dependence of the formation NH4+ and/or NO3− ions on chemical structure has been examined in TiO2 photocatalyzed oxidations various amino acids, amides, and nitrogen-heterocyclic compounds. primary groups amide moiety are converted photocatalytically predominantly to ions, whereas hydroxylamino group N-hydroxysuccinimide is photoconverted ion. Results show that nitrogen at 1-position imidazole mainly ion by analogy with equivalent atom pyrrole; 3-position transformed into Formation ammonium faster than nitrate all but substrate.
