The particulate material includes an alumina material and a silica dopant. The particulate material includes crystallite particles with a crystallite particle size of less than about 10 nm. Crystallite particles are stacked together to form primary particles with a primary particle size of less than about 500 nm. The primary particles together agglomerate to form secondary particles with a secondary particle size greater than about 1 μm. The particulate material has an average pore size of 8 nm or more.
