<p class="MsoNormal" style="text-align:justify"><span lang="EN-US" style="font-family:"Arial","sans-serif"">The development of new green industrial NO<sub>x</sub> control catalytic technologies operated in a low-temperature range (ca. 120-200<sup>o</sup>C),
and based on other than ammonia reducing agents, remains a very important target since it could reduce the operational and investment costs compared to the present NH<sub>3</sub>- and urea-SCR technologies, and be easily retrofitted in existing industrial
plants. The design of such new de-NO<sub>x</sub> catalytic systems would largely be facilitated if important kinetic and mechanistic information at the molecular level can be obtained using
<i>in situ</i> kinetic and spectroscopic techniques (<i>operando</i> methodology). For example, the design of an industrial supported metal/metal oxide catalytic system would require to know whether and to what extent the support material influences the catalytic
rate (<i>bifunctional</i> catalysis). It becomes also important to know how the support chemical composition influences specific kinetic parameters, such as the surface concentration of the active intermediate species, their site reactivity (k, s<sup>-1</sup>),
and the chemical nature of the active intermediates that are found in the rate-controlling step.<o:p></o:p></span></p>

<p class="MsoNormal" style="text-align:justify"><span lang="EN-US" style="font-family:"Arial","sans-serif"">The application of Steady-State Isotopic Transient Kinetic Analysis (SSITKA) technique and other transient isotopic experiments coupled with infrared
spectroscopic measurements have proven to provide significant understanding towards several important de-NO<sub>x</sub> catalytic reactions. The latter is demonstrated through the present lecture by providing examples from the literature regarding the H<sub>2</sub>-SCR
of NO<sub>x</sub> control. In particular, the effect of support chemical composition, Pt metal particle size, and reaction temperature on supported-Pt performance, the nature, location (metal vs. support) and surface concentration of active and inactive NO<sub>x</sub>
adsorbed reaction intermediate species, and the role of gaseous oxygen on the de-NO<sub>x</sub> reaction rate and N<sub>2</sub>-selectivity will be reviewed.<o:p></o:p></span></p>
