Fabrication of apatite-type La_(9.33)(SiO_4) _6O_2hollow nanoshells as energy-saving oxidative catalysts

摘要

Apatite-type La_(9.33)(SiO_4)_6O _2hollow nanoshells were successfully synthesized by a controlled route. These oxide-ion-conducting hollow nanoshells were used to catalyze oxidative coupling of methane, and an enhanced catalytic performance at relatively low temperature was realized. The high-activity and energy-saving features were attributed to their hollow nanostructures and oxide ion conductivity.
