Gd0.1Ti0.1Zr0.1Ce0.7O2 solid solution with crystallite size of 10 nm, specific surface area of 85 m2 /g and pore size of 2–6 nm has been prepared by a simple co-precipitation method with sonication and characterized by several methods. Among the characterization methods was laser desorption ionization-time of flight mass spectrometry (LDI-TOF) which was used to characterize the surface of the catalyst (fresh and used in CO oxidation) and thereby determine the catalytic sites (active sites of oxidation).
