Reducibility of 6wt.% cobalt impregnated on zeolite Y in sodium and proton form (6Co/NaY and 6Co/HY, respectively) was studied mainly by X-ray absorption spectroscopy including X-ray absorption near edge spectroscopy (XANES) and extended X-ray absorption fine structure (EXAFS) along with other techniques such as X-ray diffraction. The results indicated that the physicochemical properties of Co strongly...
