Abstract

The metal–support interaction in supported heterogeneous catalyst systems has been long known to affect the activity and selectivity of the catalyst. In this paper, we will combine scanning transmission electron microscopy with electron energy-loss spectroscopy to investigate the interaction between the Mn promoter, the Co nano-catalysts, and the SiO2 support. By comparing these results with similar catalysts on TiO2 supports, we will discuss the effect of metal–support interaction and interfacial oxygen vacancies on the catalyst morphology.
