TiO2 interpenetrating networks decorated with SnO2 nanocrystals: enhanced activity of selective catalytic reduction of NO with NH3Electronic supplementary information (ESI) available. See DOI: 10.1039/c4ta05503a

Highly branched TiO 2 interpenetrating network architectures decorated with SnO 2 nanocrystals were fabricated through a sacrificial-template approach for selective catalytic reduction of NO with ammonia. Such unique architectures demonstrate outstanding catalytic activity for NO conversion (∼90%), high N 2 selectivity (∼100%), good stability and strong resistance to SO 2 and H 2 O poisoning over a broad temperature range (75-325 °C). Highly branched SnO 2 -decorated TiO 2 interpenetrating network architectures were fabricated with superior denitration catalytic activity over a broad temperature range.
