摘要：In this paper, Pt supports on carbon black powder (Vulcan XC-72) were synthesized via a hydrothermal method for selective catalytic reduction (SCR) of NO with H-2 in the presence of 2 vol% O-2 over a wide temperature of 20-300 A degrees C. The results showed that the 3 and 5 wt% Pt/C catalysts resulted in high NO conversion (> 90 %) over a temperature range of 120 to 300 A degrees C, and the maximum NO conversion of 98.6 % was achieved over 5 wt% Pt/C at 120 A degrees C. Meanwhile, the influence of SO2 and H2O on the catalyst performance of 3 wt% Pt/C was investigated. The catalysts exhibited good SO2 poisoning resistance when the SO2 concentration was lower than 260 ppm. Moreover, a positive effect on NO conversion was detected with the addition of 3 and 5 vol% H2O in the feed gas stream.
