A Novel Photo‐thermochemical Approach for Enhanced Carbon Dioxide Reforming of Methane Academic Article uri icon

abstract

  • AbstractWe report a new approach for photothermochemical CO2 (dry) reforming of methane (PTCDRM) to produce syngas by using concentrated sunlight as the energy input. A unique catalyst, Ptsupported Simodified CeO2, was designed for this novel PTCDRM reaction by integrating photocatalytic and thermocatalytic effects, for which Pt was the thermocatalytic DRM catalyst and cocatalyst for photocatalysis, CeO2 was the DRM support and semiconductor photocatalyst, and Si was the promoter and stabilizer. Under irradiation of the equivalent of 30suns at 600C in 30h, the production rates of H2 and CO reached stable levels of 90 and 154mmolg1h1, respectively, which were five and two times higher than those obtained in the dark at the same temperature. The significantly enhanced catalytic performance and stability under solar irradiation, resulting from synergy between the photocatalytic and thermocatalytic effects, demonstrates the feasibility of a new direction in lowcarbon fuel production from sunlight.
