Nano-sized Titanium-zirconia Catalyst Modified by Sulphate as an Efficient Catalyst

摘要: A series of sulphate modified titanium zirconia catalysts was set up by a sol-gel technique. All samples were calcined at several temperatures 500, 600, and 750°C for 3h. The investigation methods structural characteristics used such as; thermal analysis, powder X-ray diffraction (XRD), transmission electron microscope (TEM), Scanning (SEM). In addition, the textural features evaluated from low temperature adsorption N2 -196 oC. measurement surface acidity determined with non aqueous titration n-butylamine in acetonitrile. Peckman condensation production cumarin testing catalytic activity constructed catalysts. photo degradation methylene blue dye using catalyst investigated.
