Co–Ni alloy supported on CeO2 as a bimetallic catalyst for dry reforming of methane

Dry reforming of methane (DRM) is an effective route to convert two major greenhouse gas (CH4 and CO2) to syngas (H2 and CO). Herein, in this work, monometallic Ni/CeO2 and a series of bimetallic Co–Ni/CeO2 catalysts with Co/Ni ratios between 0 and 1.0 have been tested for DRM process at 600–850 °C, atmospheric pressure and a CH4/CO2 ratio of 1. The catalysts were characterized by X-ray diffraction, hydrogen-temperature programmed reduction,...
