中文摘要	The catalytic performance and the promotional mechanism of sulfation for selective catalytic reduction of NO by CH4 over sulfated titanium-loaded In (In/STi) were investigated. An enhancement of catalytic activity was obtained over the In/STi catalysts. Sulfation influenced the existent state of surface indium species and determined the activation species of CH4. Py-IR analysis showed that the sulfated In/STi catalyst had strong Bronsted acid sites, which were beneficial to the formation of active InO+ species. DRIFTS studies further revealed the distinguish reaction intermediates of CH4-SCR of NO over the sulfated and unsulfated catalysts. On the In/TiO2 and TiO2 catalysts, the activation species of CH4 was the fully oxidized products of CO2 and H2O, while on the STi and In/STi catalysts, HCOO-, the real reductant for CH4-SCR of NO, was detected as the main intermediate species. In addition, the formation of HCOO- was the rate-determining step in CH4-SCR of NO on the In/STi catalyst.
