Syngas production at a near-unity H2/CO ratio from photo-thermo-chemical dry reforming of methane on a Pt decorated Al2O3–CeO2catalyst

At 700 °C under 30-sun equivalent irradiation, the Pt–Al–Ce catalyst shows a high DRM efficiency and a near-unity H 2 /CO ratio. The concentrated sunlight facilitates photocatalytic reactant activation and leads to enhanced catalytic efficiency.
