A sequence of alkali metal cation-exchanged Co metal-organic frameworks(Co-MOFs),therein after denoted as M@Co-MOF,M=Na+,K+,Rb\and Cs+,was prepared and used as the precursors to obtain the corresponding alkali doped cobalt oxide(defined as M/C03O4,M=Na+,K\Rb\and Cs+)through calcination under air *** cobalt oxide modified by unifbnn alkali metals exhibited a significant promotion of catalytic activity for CO *** activity of M/Co3O4 decreased in the order of Cs+>Na+>K+>Rb+.Experimental and theoretical results revealed that the anionic skeleton of Co-MOF could tacilely adsorb alkali metal cations and play a cnicial role in the formation of higlily unilonn alkali doped cobalt *** further characterizations,such as temperature-programmed reduction of H2(H2-TPR),oxygen temperature-programmed desorption(O2-TPD),X-ray photoelectron spectroscopy(XPS),and in situ diffuse reflectance infrared Fourier transiorm(DRIFT)spectra demonstrated that the enlianced catalytic activity is originated from the interfacial electron transfer as well as weakened the Co-O bond strength,which promoted oxygen desorption from CO3O4 and fomiation of cobalt species with the lower valence *** Cs/Co3O4 catalyst was maintained for 60 h without deactivation and still showed a high activity in the presence of water.

Bearing unique redox nature and high oxygen storage capacity,ceria(CeO_(2))has always been a promising CO oxidation catalyst support for gold(Au)catalysts and the ***,a series of Au-CeO_(2)-P(P stands for pH value)samples was prepared by a co-precipitation method with the assistance of an alkaline environment and amino groups functionalized ordered mesoporous polymer(OMP-NH_(2)).Afterward,all samples described above were characterized that the Au-CeO_(2)-P catalysts are made of Au-Ce-O solid solution and Au nanoparticles(NPs)supported on CeO_(2).It turns out that OMP-NH_(2) is not just a simple sacrificial template for mesoporous structure,but also plays an important role as an amino source,explaining the presence of rich oxygen *** to the concentration of oxygen vacancies in Au-Ce-O solid solution is the key factor for the oxygen mobility of CO oxidation,the catalytic results also demonstrate that the catalytic activity of Au-CeO_(2)-P catalysts is related to the concentration of their oxygen ***,Au-CeO_(2)-9.6 with a highest concentration of oxygen vacancies(as high as 13.98%)in Au-CeO_(2)-P catalysts exhibits the best catalytic activity(complete conversion at 10℃).
