Nanocrystalline ceria with high surface area and mesoporosity was prepared by template-assisted precipitation method. The method of preparation was facile, using low-cost reagents and could be performed on a large scale. Cerium oxide support was characterized by Brunauner – Emmett - Teller (BET), X-[r]
