Abstract

Infrared spectra of NO, NO2 and CO adsorbed on Rh/Al2O3 have been recorded in order to identify the role of surface Rh-NO+ species in the reactions of NO and CO on Rh surfaces. Rh-NO+ was generated by thermally activated adsorption of NO, adsorption of NO on oxidised Rh or by adsorption of NO2. The latter also gave adsorbed nitrate on both Rh and the alumina support. In the presence of CO, Rh-NO+ acted as a precursor of the Rh(CO)(NO) mixed surface complex of CO and NO.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
