Content SummaryThe performance of altervalent doped TiO2 catalysts under oxidative coupling of methane conditions is investigated. It is shown that higher-valence doping (W6+, Nb5+, Ta5+) of TiO2 enhances significantly methane conversion activity and reduces selectivity to nearly zero levels. On the other hand, doping TiO2 with lower valence cations (Li+, Zn+2) has a small influence on activity but results in a significant enhancement of selectivity. These results are attributed to alterations of the bulk electronic structure of the semiconductivity catalysts as well as to alterations of surface parameters such as acidity/basicity characteristics, oxygen ion mobility and lattice oxygen reactivity.en
