Abstract
Ordered mesoporous tungsten-doped MoO2 was synthesized by a nanocasting method. The Li storage performance of mesoporous MoO2 is significantly improved by tungsten doping, which exhibits a reversible capacity of 700 mA h g(-1), better cycling and rate performance. This material combines the advantages of the high theoretical capacity of MoO2 and the better electroactivity of WO2.
