Microwave-Assisted CO Oxidation over Perovskites as a Model Reaction for Exhaust Aftertreatment—A Critical Assessment of Opportunities and Challenges

We introduce a microwave (MW)-assisted heterogeneous catalytical setup, which we carefully examined for its thermal and performance characteristics. Although MW-assisted catalysis has been widely explored in the past, there is still need attention towards specific experimental details, may complicate interpretation of results comparability general. In this study discuss technical material related factors influencing obtained data from catalysis, specifically regards to oxidation carbon monoxide over selected perovskite catalyst, shall serve as model reaction exhaust gas aftertreatment. A high degree between different experiments, both terms setup catalysts, necessary draw conclusions regarding promising technology. Despite significant interest fundamental applied research, many questions controversies remain are discussed study. series deciding parameters presented influence on discussed. To control these challenge but also an opportunity gain advanced insight into develop new materials processes. The discussion based upon experiments conducted monomode system employing powdered solid-state oxides fixed bed reactor. covers critical aspects concerning determination actual catalyst temperature, homogeneity distribution, time, local temperature relaxation (i.e., runaway effects hotspot formation), particle size effects, flow considerations, design.
