K2WO4Al2O3Introduction strategySol-gel aluminaA series of the K2WO4/gamma-Al2O3 catalysts was prepared with different introducing strategy of the K2WO4 to alumina and characterized by means of N-2 adsorption-desorption, XRD, XPS, CO2/NH3-TPD, H-2-TPR. It was found that the different ...
Temperature-dependent Raman spectroscopy studies of K2WO4 and MgMoO4 polycrystals were performed in order to obtain information about vibrational and structural changes in these materials as a function of temperature. The stability of the monoclinic phase for both K2WO4 and MgMoO4 samples was assess...
