Multicomponent Co-based sol–gel catalysts for dry/steam reforming of methane

Abstract

The multicomponent Со–Pt–Zr/Al2O3 and Со–Pt–Zr–La/Al2O3 catalysts were prepared by the sol–gel method. The modified Pechini method was used as a sol–gel approach to synthesize a system containing Co, Pt, Zr, and La. The sol–gel materials prepared by such a manner were incorporated into alumina in order to form the catalyst granules. The physicochemical properties of the catalysts were studied by a number of methods (TEM, SEM, BET, XRD, H2-TPR). It was found that the synthesized multicomponent catalysts are highly dispersed systems composed of metal oxides and various microalloys such as the bimetallic Co–Pt and perovskite type structures—LaCoO3 and LaAlO3 having mainly the particle size 200 h.
