TiO2 interpenetrating networks decorated with SnO2 nanocrystals: enhanced activity of selective catalytic reduction of NO with NH3

Abstract

Highly branched TiO₂ interpenetrating network architectures decorated with SnO₂ 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 N₂ selectivity (∼100%), good stability and strong resistance to SO₂ and H₂O poisoning over a broad temperature range (75–325 °C).
