Induction heating catalysis: Carbon dioxide methanation on deactivation-resistant trimetallic PdRe/Ni nanoconjugates with Ni-supports

Abstract

The objective of the present study was to assess the scalability of the methanation na nocatalysis controlled by induction heating. We constructed a library of Ni-scaffolds supporting nano-Pd/Re blends using a nano-transfer method that we developed pre viously as a way to generate nanoparticles and decorate with them various carriers ef fective in environmental green chemistry applications. We compared their reactivity with that of powdered systems. Through testing these catalyst systems in low-temperature IHC CO2 methanation, we discovered that a high CO2 methanation activity was closely associated with the oxide-passivation of the surface structures. Unexpectedly, a com prehensive XPS analysis of the catalyst materials’ surfaces unveiled the presence of carbon deposits in both the original metals and the constructed and reacted catalysts, although this phenomenon did not diminish the catalysts’ reactivity. Our research in dicates that a new platform is coking resistant, while IHC control allows for 58 ℃ reduction in CO2 methanation temperature compared to silica-supported catalysts controlled me thanation performed in the preheated gas stream
