Ordered mesoporous TiC–C (OMTC) composites were prepared and served as catalysts for nonaqueous Li–O2 batteries. The OMTC cathodes showed high specific capacity, low overpotential and good cyclability. Furthermore, the discharge and charge processes were investigated extensively by XRD, XPS and in situ GC-MS methods.
