Mo doping leads to higher NH₃ and lower NO adsorption on sulfated catalyst, reducing inert surface nitrate formation
Mo doping effectively lowers the H₂O dissociation barrier, favoring competitive NH₃ adsorption
Compared to CeO₂-TiO₂, SO₂ adsorption energy and oxidation ability on CeMoTi are lower, hindering SO₃ formation/desorption
