Nitric oxide homogeneous catalysis

However, it is kinetically inert and requires a catalyst for this and many other of its reactions. Generally, heterogeneous catalysts such as CuO and Rh203 are used, though homogeneous catalysis has been reported for some reactions of nitric oxide. For example, a number of platinum metal complexes, as well as metals and metal oxides, can catalyze the oxygen transfer reaction ...

This quite general and highly selective introduction on nitric oxide chemistry had the aim to stress the importance of reviewing the organometallic and coordination chemistry of NO, whenever this molecule may get connected to a function in homogeneous catalysis. This chapter will describe well-established examples of the versatility of nitrosyl-based homogeneous catalyses and maybe it will help to identify nitrosyl niches worth for exploitation and development to accomplish new and better performing transition metal catalysts, in particular those with middle transition elements. 

The oxidation of sulfur dioxide using nitric oxide as a catalyst is an example of homogeneous catalysis, which is the use of a catalyst in the same phase as the reacting species. The catalyst NO and the reacting species SO2 and O2 are all in the gas phase. Another example occurs in the oxidation of thallium(l) to thallium(lll) by cerium(TV) in aqneous solution.
