“…[8] N 2 O is believed to participate further reactions to produce N 2 . [9] Its reduction by CO over Rh has been extensively studied in the past, [9][10][11][12] while H 2 as reducing agent is far less investigated, [13] which is also of great importance.…”

The reduction of NO with CO and H2 as the reductants was investigated on the rhodium‐based catalyst over a temperature range of 150–400 °C. Micro‐kinetic modelling method was utilized to compare the activities of CO and H2. Quasi‐elementary mechanisms of NO‐CO and NO‐H2 consisting of 11 and 25 steps, respectively, were proposed. The reaction steps and kinetic parameters were derived from literature and some parameters were optimized to fit the experimental data. Furthermore, to verify the validity range of the developed mechanism, the reaction intermediate N2O reduction by CO and by H2 over Rh were investigated. Over a wide range of reaction conditions, the detailed mechanism predicted experimental results quite well for both NO and N2O conversions with CO and/or H2 as reductant. The phenomenon that NO‐CO and NO‐H2 reactions commenced at similar temperature can be interpreted by the hindered H2 dissociative adsorption steps by extensive NO adsorption. Reaction profiles such as fractional coverages, reaction pathway and sensitivity analysis provided valuable insight into the reaction systems. N2O plays a crucial role in N2 formation for both NO‐CO and NO‐H2 reaction systems. The routes involving N2O formation and decomposition were identified as the dominant pathway in N2 formation at low temperatures.

Both CO and NO are important, environmentally harmful industrial gases. The reaction of CO and NO to produce CO and N has stimulated much research interest aimed at degradation of these two gases in a single step. Herein, we report an efficient CO oxidation by NO catalyzed by a (PNN)Ru-H pincer complex under mild conditions, even with no added base. The reaction is proposed to proceed through a sequence of O-atom transfer (OAT) from NO to the Ru-H bond to form a Ru-OH intermediate, followed by intramolecular OH attack on an adjacent CO ligand, forming CO and N. Thus, the Ru-H bond of the catalyst plays a central role in facilitating the OAT from NO to CO, providing an efficient and novel protocol for CO oxidation.
