Light-Driven Dry Reforming of Methane on Metal Catalysts

Dry reforming of methane (DRM) is promising to produce syngas with low ratios of H-2/CO with the feedstock of greenhouse gases, CH4 and CO2. Synthesizing active and selective catalysts and developing the protocols for stable and durable operation is crucial to implement DRM for the production of syngas. High-temperature 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.

Automated summary

Dry reforming of methane (DRM) offers the potential to produce syngas with low H2/CO ratios using greenhouse gases methane and carbon dioxide as feedstock. The key to implementing DRM for syngas production is synthesizing active and selective catalysts and developing stable and durable operation protocols. High-temperature operation and carbon deposition on catalyst surfaces are significant challenges hindering the adaptation of DRM in industry.
