Photoacoustic spectroscopy (PAS) has been used to monitor the surface acidity of solid (alumina-silica) catalyst, since PAS has the inherent advantage of measuring absorption bands of solid surfaces conveniently. Three kinds of acidic sites have been detected and their relative abundance estimated.
