Abstract

Zeolite In,H-, Co,H-, and Co,In,H-ZSM-5 were characterized by operando diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), temperature-programmed reduction by hydrogen (H₂-TPR), X-ray photoelectron spectroscopy (XPS), and activity in the selective catalytic reduction of NO (NO-SCR) by methane. The catalysts were shown to contain indium as [InO]⁺/[InOH]²⁺ cations, whereas cobalt was in the form of Co²⁺/[Co-OH]⁺cations or Co-oxide clusters in amounts controlled by the applied preparation method. The NO-SCR by methane was shown to proceed in two coupled processes on distinctly different catalytic sites. One of the processes is the oxidation of NO to N0₂ by oxygen over Brønsted acid sites and/or cobalt-oxide species giving NO/NO₂ gas mixture (NO-COX reaction). The other process is the N₂ formation, which is the result of the reaction of methane and the NO/NO₂ mixture (CH₄/NO-SCR reaction). Molecules of NO and N0₂ were shown to become activated together as NO⁺/NO₃^- ion pair in reaction with [InO]⁺/[InOH]²⁺ or Co²⁺/[Co-OH]⁺ sites. Operando DRIFTS results suggested that the reaction of methane and N0₃- generates an intermediate that rapidly reacts with the NO⁺ to give N₂. The promoting effect of the cobalt was related to the significantly higher NO-COX activity of Co-oxide clusters than that of the Brønsted acid sites. The accelerated NO-COX reaction speeds up the formation of NO⁺/NO₃^- species and the rate of the methane activation, being the rate-determining step of the NO-SCR reaction. It was also shown that the NO-SCR reaction can proceed if NO-COX and CH_4/NO-SCR active sites are separated in space. In order to avoid rate controlling NO₂ transport between the sites close proximity of the sites is favorable.
