1. A method of making a composition, the method comprising:
colloidally-dispersing red mud with alumina by mixing colloidal red mud with colloidal alumina to form a colloidal mixture of red mud and alumina;
drying the colloidal mixture at a first temperature to form a dried mixture; and
calcining the dried mixture at a second temperature higher than the first temperature to form dried and calcined catalytic particles comprising colloidally-dispersed red mud and alumina.
