Light-Driven Dry Reforming of Methane on Metal Catalysts

摘要

Dry reforming of methane (DRM) is promising to produce syngas with low ratios of H_2/CO with the feedstock of greenhouse gases, CH_4 and CO_2. Synthesizing active and selective catalysts and developing the protocols for stable and durable operation is crucial to implement DRM for the production of syngas. Hightemperature operation and deposition of carbon on the surface of catalysts represent two significant challenges to prevent the adaption of DRM in industry. Light-driven catalysis of DRM can lower operating temperature and reduce the deposition of carbon, offering the promise to tackle the challenges faced in traditional thermocatalysis of DRM. Herein, the light-driven DRM on metal catalysts of various structures, highlighting the encouraging promise of photocatalysis for DRM, is overviewed.
