摘要：
A Ti-Ce-Cu-W catalyst prepared by solution combustion synthesis (SCS) showed high low temperature activity for selective catalytic reduction (SCR) of NO with ammonia. Different fuels and different fuel/oxidant (F/O) ratios were introduced to investigate the optimum synthesis conditions for the Ti0.75Ce0.15Cu0.05W0.05O2-delta catalyst. The results showed that samples using citric acid and glycine as a fuel showed good low temperature catalytic activity and the catalytic activity could be improved through increasing the F/O ratio. The sample with a F/O ratio of 1.5 obtained around 70% NO conversion at a temperature of 150 degrees C.
