Abstract
Proton adsorption isotherms derived from potentiometric titration of h igh surface area alpha aluminas were deconvoluted to yield proton affi nity distributions. The results reported provide another view and addi tional support to the conclusion reached by Mao and Vannice [Appl. Cat al. A, 111 (1994) 151] that these materials prepared by topotactic tra nsformation of diaspore have surface properties unlike those of either low surface area alpha-Al2O3 or transition aluminas.
