Mechanism of Heterogeneous Catalyst Nitric oxide (nitrogen oxide or nitrogen monoxide) is a colorless gas with the formula NO.It is one of the principal oxides of nitrogen.Nitric oxide is a free radical: it has an unpaired electron, which is sometimes denoted by a dot in its chemical formula ( N=O or NO). The scope of the catalytic coupling process encompasses a range of acidic pronucleophiles that allow stereospecific construction of carbon-oxygen and carbon-nitrogen bonds. Selective catalytic reduction (SCR) is a means of converting nitrogen oxides, also referred to as NO x with the aid of a catalyst into diatomic nitrogen (N 2), and water (H 2 O).A reductant, typically anhydrous ammonia (NH 3), aqueous ammonia (NH 4 OH), or a urea (CO(NH 2) 2) solution, is added to a stream of flue or exhaust gas and is reacted onto a catalyst.As the Mechanism of Heterogeneous Catalyst Antimony(III) oxide is the inorganic compound with the formula Sb 2 O 3.It is the most important commercial compound of antimony.It is found in nature as the minerals valentinite and senarmontite.
