Abstract

Silica-supported heteropoly acids have been studied by microcalorimetry. The results are greatly dependent on both the activation temperature and the heteropoly acid, in agreement with the n-hexane cracking experiments. It is shown that very strong acid sites are formed on H4SiW12O40/SiO2 activated at 623 K and on H3PW12O40/SiO2 activated at 423 K.
