摘要：
Engineering surface oxygen species to tune catalytic selectivity of oxides is an emerging hot topic in heterogeneous catalysis. Here, we demonstrate that HCl treatment can controllably chlorinate CeO2 at surface oxygen vacancies and tightly regulate the content of surface oxygen vacancies (O-s). Structure-property studies reveal that the decreased ratio of O-s quasi-linearly promotes the C3H6 selectivity in oxidative dehydrogenation of propane (ODHP).
