Turning Poison into Power: In-situ Carbon-Nanotube-Promoted Microwave Absorption Sustains High-Efficiency Methane Dry Reforming

Abstract

We report an unconventional carbon-promoted effect in Ni/CeO2 catalysts enhancing microwave-assisted dry reforming of methane (MA-DRM). Rather than causing deactivation, in-situ generated carbon nanotubes transform the catalyst into a self-optimizing system, acting as dielectric loss promoters that boost microwave energy coupling and sustain efficient DRM performance overall.
