Low temperature dry reforming of methane over plasmonic Ni photocatalysts under visible light irradiation

Author affiliations

Abstract

Low temperature CO2 conversion with CH4 into syngas (dry reforming of methane, DRM) was achieved over a plasmonic Ni/Al2O3 photocatalyst with a high conversion of CO2 (21%) and CH4 (20%) using a fixed-bed flow reactor at 473 K. The formation rates of CO and H2 were 1.87 and 1.20 mmol h−1, respectively, and these values were over 47 times higher than those using the Ga2O3 photocatalyst previously reported by our group. To the best of our knowledge, this is the first report in which high formation rates of CO and H2 were achieved at 473 K in the DRM reaction under visible light. Besides, the CO/H2 ratio was successfully controlled by changing the CO2/CH4 ratio in the feed gas mixture.
