Nitrogen Monoxide and Nitrous Oxide Binding and Reduction

Abstract

46Table 2.1 The typical coordination geometry of NO complexes predicted by the Enemark-Feltham electron counting formalism. Coordination number (CN) Idealized geometry CN = 4 CN = 5 CN = 6

One metal is enough: a nickel complex reduces nitrate anions to nitrogen gas

“…9a. Given that both gases are often encountered together for example in the automobile exhaust gas,1,5 this finding is particularly interesting and suggests a potential alternative to selective catalytic reduction process that is currently used in the automobile industry 5. Efforts towards exploiting this feature and developing such a technology for removing NO is currently underway in our laboratory.…”

“…The production of hazardous nitrogen oxides (NO x ) from human industrial activity is a serious environmental concern 1. While both nitrogen dioxide (NO 2 ) and nitric oxide (NO) are hazardous pollutants found in automobile exhaust,2 nitrate (NO 3 – ) has also recently been scrutinized as a water pollutant.…”

Peroxynitrite chemistry derived from nitric oxide reaction with a Cu(ii)–OOH species and a copper mediated NO reductive coupling reaction

“…3). 12 In fact, for the [(BA)Cu II (OOH)] + ( 2 ) + •NO (g) reaction, we detected significant amounts of N 2 O (g) (GC analyses). However, only a trace of nitrite could be detected, and as described above, NO 3 − was formed in high yield (eq 2).…”

Fixation of nitrous oxide (N2O) by 1, 4, 2, 5‐diazadiborinine: A DFT study

“…[5] So, it is not surprizing that a considerable effort is required for chemical activation of N 2 O. [6] Actually, when a transition metal and N 2 O are brought together for an interaction to start, it is bound poorly due to its weak r-donor and p-accepter properties. [7,8] In the nature N 2 O is converted to N 2 and H 2 O by the metalloenzyme nitrous oxide reductase during the process of biological denitrification.…”
