A complete amorphous and highly ordered Ce-Ti catalytic membrane was prepared for simultaneously removing the particulates and NOx. Results showed that the presence of Ce species suppressed the phase transformation of the anatase TiO₂, consolidated the pore framework and well retained the ordered hexagonal pore structure. As a result, the highly ordered Ce_0.2TiO_x catalyst presented approximately 100% NO conversion in a wide temperature of 175~350℃ and satisfactory SO₂ tolerance because of large surface and formation of the Ce-O-Ti species. Furthermore, the prepared Ce_0.2TiO_x catalytic membrane slightly enhanced the operating pressure drop and delivered an almost similar selective catalytic reduction (SCR) activity for NO_x with the catalyst powder.
