Abstract
We have used X-ray phase analysis, transmission electron microscopy, and temperature-programmed reduction to study cobalt–zirconium catalysts. The most active samples are characterized by higher dispersity of both the support (L = 12-13 nm) and the active component (L ≤ 3 nm); modification of the zirconium dioxide with yttrium oxide increases the thermal stability of the catalysts. We have shown that the activity of the catalysts is determined by both the strength of oxygen–catalyst binding and the acidic properties of the catalyst surface.
