Catalytic Decomposition of Formaldehyde on Single Rhodium Atoms.

Abstract

The interaction of H2CO with alumina-supported Rh has been studied by transmission infrared spectroscopy. It has been shown that isolated Rh atoms catalyze the decomposition of H2CO to produce carbonyl hydride species H(x)Rh-CO (x = 1,2). Species of the type Rh(HCO) and Rh(HCOH) are not observed to form in detectable amounts. Hydride bonding to rhodium carbonyl species is associated with electron donation to Rh causing a decrease in nu sub CO due to electron donation into 2 pi*-CO orbitals. Hydride displacement by CO may occur on exposure to CO(g). The conversion of the species H-Rh(CO)2 to H-Rh(CO) has been followed spectroscopically during desorption. (Author)
