The present invention provides porous body precursors and shaped porous bodies. Also included are catalysts and other end-use products based upon the shaped porous bodies and thus the porous body precursors. Finally, processes for making these are provided. The porous body precursors are germanium doped and comprise a precursor alumina blend. It has now surprisingly been discovered that inclusion of germanium, alone or in combination with such a blend, in porous body precursors can provide control over, or improvements to, surface morphology, physical properties, and/or surface chemistry of shaped porous bodies based thereupon. Surprisingly and advantageously, heat treating the shaped porous bodies can result in additional morphological changes so that additional fine tuning of the shaped porous bodies is possible in subsequent steps.
