Abstract
The activity of monometallic (Ni/γ-Al2O3, Co/γ-Al2O3) and bimetallic (Ni-Co/γ-Al2O3) catalysts supported on γ-aluminium oxide for dry reforming of methane into synthesis gas was studied. It was determined that the bimetallic catalyst is more active than monometallic. A set of methods (X-ray phase analysis and temperature-programmed reduction with hydrogen) was applied to reveal that the addition of Co to the composition of Ni/γ-Al2O3 leads to the formation of a surface bimetallic alloy Ni-Co, which plays an important role in suppressing the formation of carbon deposits on the catalyst surface and increasing its activity.
