Abstract

A silicon carbide-supported silver catalyst used in the oxydehydrogenation of ethylene glycol to glyoxal has been studied by scanning tunneling microscopy. The surface morphology depends upon reaction conditions. Silver particles normally sinter into large plates covering the support. However, in the presence of diethylphosphite there is a chemical erosion which results in a tortuous and fractal-like surface.
