High surface area aluminum phosphate-alumina compositions are prepared by reaction of a mixture comprising an aluminum alkoxide and an organic phosphate such as trialkyl or triaryl phosphate, in the presence of moist air to form a precipitate, separating the precipitate from the mixture, drying and calcining the precipitate and recovering a high surface area aluminum phosphate-alumina product which can be used as catalyst support or catalyst component, especially for hydrocarbon treating and conversion processes.
