Abstract
Whilst there is merit in using NH3 or CO as probes to determine the su rface acidity of solid catalysts by thermal and/or spectroscopic means , we show that, following Wakabayashi et al., quantitative spectroscop ic changes accompanying the adsorption of dinitrogen offer more reliab le assessments. Subtle differences arising from the use of N-2 as betw een CoALPO and zeolitic (aluminosilicate) catalysts are also discussed .
