Release Summary
Catalytic dry reforming of methane (DRM) is a key reaction for the sustainable utilization of major greenhouse gases, CO2 and CH4. However, conventional DRM often suffers from severe catalyst deactivation due to high temperature requirements. Applying direct current (DC) to catalyst materials has emerged as a promising strategy to overcome these limitations, yet the underlying DC-enhanced catalytic mechanism remains elusive. Here, we unveil the non-thermal catalytic origin of DC-applied DRM over Pd/CeO2 through multimodal operando analyses, providing a microscopic physicochemical framework for the rational design of next-generation DRM catalysts beyond the limitations of conventional thermal catalysis.
