A High-Throughput Screening Approach to Identify New Active and Long-Term Stable Catalysts for Total Oxidation of Methane from Gas-Fueled Lean–Burn Engines

A unique high-throughput approach to identify new catalysts for total oxidation of methane from the exhaust gas of biogas-operated lean-burn engines is presented. The approach consists of three steps: (1) A primary screening using emission-corrected Infrared Thermography (ecIRT). (2) Validation in a conventional plug flow gas phase reactor using a model exhaust gas containing CH4, O2, CO, CO2, NO, NO2, N2O, SO2, H2O. (3) Ageing tests using a simplified exhaust gas (CH4, O2, CO2, SO2, H2O). To demonstrate the efficiency of this approach, one selected dataset with a sol-gel-based catalysts is presented. Compositions are 3 at.% precious metals (Pt, Rh) combined with different amounts of Al, Mn, and Ce in the form of mixed oxides. To find new promising materials for the abatement of methane, about two thousand different compositions were synthesized and ranked using ecIRT, and several hundred were characterized using a plug flow reactor and their ageing behaviour was determined.

“…In particular, partly substituting B-site cations with other elements can modify the redox properties to specifically enhance their catalytic activity [124]. As one kind of hierarchical porous structure, 3DOM structure can reduce the flow resistance and promote the contact between catalyst and reaction gases in the methane combustion [125,126]. The appropriate pore diameters, large surface area, abundant active sites and good mass transfer property of 3DOM structure are also favorable for the reaction [127,128].…”

Three-dimensionally ordered macroporous (3DOM) perovskite materials have attracted the interest from researchers worldwide due to their unique macroporous structure, flexible composition, tailorable physicochemical property, high stability and biocompatibility. In particular, they were widely used in environmental field, such as photocatalysis, catalytic combustion, catalytic oxidation and sensors. In this review, the recent progresses in the synthesis of 3DOM perovskite materials and their environmental applications are summarized. The advantages and the promoting mechanisms of 3DOM perovskite materials for different applications are discussed in detail. Subsequently, the challenges and perspectives on the topic are proposed.

“…SVUV-PIMS, in combination with quasi in situ XPS, was also employed to study the reaction mechanism of methane combustion catalyzed by a hierarchical porous flower-like NiCo 2 O 4 supported Pd catalyst. [85] C 1 s XPS spectra indicated the formation of OCHO species on the catalyst surface during the methane oxidation reaction, whose intensity initially increased with the temperature and reached the maximum at 240°C, then gradually weakened with the temperature further increasing. Gas-phase HCHO (m/z = 30) was detected during the reaction by SVUV-PIMS ionized at the photon energy of 11.0 eV, and its intensity obviously grew with the temperature increas-ing from 250 to 350°C.…”

Heterogeneous catalytic reactions always involve surface intermediates on catalyst surfaces, and some of them also involve reactive and unstable gas-phase intermediates such as radicals and alkyl hydroperoxides. Online detection of these gas-phase intermediates is of great importance for fundamentally understanding reaction mechanisms of relevant heterogeneous catalytic reactions, designing structures of efficient catalysts and optimizing reactors. However, it has remained a long-time challenge due to the lack of routine characterization techniques. Herein we review recent progress on applications of photoionization mass spectrometry in online detection of reactive and unstable gas-phase intermediates in heterogeneous catalytic reactions. The development and advantages of photoionization mass spectrometry and the relevant equipment setup for heterogeneous catalysis studies are also described. Finally, a future perspective is given.[a] Dr. * (m/z = 15), C 2 H 5 * (m/z = 29) and allyl radical (CH 2 CHCH 2 * 4 5 6 7 8
