“…Selective catalytic oxidation (SCO) of ammonia is a technology which can be used as an environmentally friendly method of ammonia abatement where N 2 and H 2 O are produced as the major products. Both transition metals and noble metals were utilized as catalysts in the SCO of ammonia. Various catalytic systems in SCO of ammonia, including noble metals, transition metal oxides, and modified zeolites, were reviewed by Chmielarz et al Among these metals, silver is considered as a promising low-temperature catalyst due to its high activity and high N 2 selectivity. , The catalytic effect of silver nanoparticles on SCO reactions as well as their interactions with other metal systems were also investigated in the literature. ,,, However, a detailed fundamental understanding of the ammonia SCO reaction mechanism on silver single crystals at the atomic/molecular level is still missing.…”

“…The first, expected at about 240 nm, is assigned to the O-Mn 2+ ligand-to-metal charge-transfer transition and the 6 A 1g → 4 T 1g ligand field transition of distorted octahedral Mn 2+ . The band at 315 nm is related to O-Mn 3+ ligand-to-metal charge-transfer transition [29]. Moreover, the broad shoulder above 350 nm is possibly related to the O-Mn 2+ ligand-to-metal 6 A 1g → 4 T 2g transition [29].…”

“…In this study, the products of oxidation of ammonia in aqueous solution are gaseous nitrogen in the gas phase and the residual NH 4 + , NO 2 − , and NO 3 − in the liquid phase. Among them, gaseous nitrogen may include N 2 , N 2 O, NO, NO 2 , NH 3 [13,43,44]. The production of NO 2 − and NO 3 − was derived from the oxidation of NH 4 + and NH 3 (aq).…”
