Abstract
Addition of alkalin metals such as K and Cs to zinc oxide-supported ni ckel-molybdenum catalysts enhances the selectivity of the carbon monox ide hydrogenation reaction towards alcohols formation. The higher frac tion is favoured. XPS studies show that alkali metals molybdenum surfa ce cause enrichment of the molybdenum surface which allows the develop ment of a phase responsible for the formation of alcohol-precursor spe cies.
