TiO2 interpenetrating networks decorated with SnO2 nanocrystals: Enhanced activity of selective catalytic reduction of NO with NH3
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 (approx. 90%), high N2 selectivity (approx. 100%), good stability and strong resistance to SO2 and H2O poisoning over a broad temperature range (75-325 °C).
