Applications of Auger and ESCA spectroscopies
A discussion of the principles, capabilities, and limitations of Auger electron spectroscopy (AES) and ESCA includes examples in which AES is used to detect surface lead poisoning of commercial copper catalysts for producing methylchlorosilanes from methyl chloride and silicon and surface poisoning by iron of a commercial palladium-alumina catalyst for selective hydrogenation of diolefins in an olefin-aromatic-alkane stream, ESCA is used to correlate the catalytic activity of a rhodium-carbon catalyst with the oxide-metal ratio, and AES, ESCA, and scanning Auger microprobe analysis are combined to show that the deactivation of a molybdena-alumina catalyst used for desulfurizing gas streams from coal gasification is caused by surface coke formation.
