Abstract

The reactivity of Rh clusters supported on ZrO<sub>2</sub> and on ZrO<sub>2</sub> modified by chemisorption of Mn, Fe, Mo carbonyls has been studied by various surface techniques such as TPD, TPR, FTIR, and by model reactions: Boudouard reaction, ethylene hydroformylation and CO/H<sub>2</sub> reaction. Four CO adsorbed species have been identified and the main effect of the modifiers is to change the distribution of the various CO moieties present on the surface, as shown by TPR and reactivity data. Mn promotes methanol formation, Fe oxygenated compounds and chain growth, Mo increases the CO reactivity, mainly to oxygenates.
