摘要

RuO₂ modified TiO₂ nanotube arrays, growing on Ti foams, are used as carbon and binder free cathodes for Li-O₂ batteries. The micrometer pores in Ti foams and nanometer pores in TiO ₂ nanotubes supply facilitated transport channels for oxygen diffusing into/out of the catalysts in discharge and charge processes. The RuO₂ catalyst exhibits outstanding catalytic active toward oxygen evolution reaction (OER), which leads the charge voltage maintaining around 3.7 V all through the battery cycling. The stability of TiO₂/Ti support, abundant oxygen transport path and favorable catalytic activity of RuO ₂ toward OER enable the Li-O₂ batteries exhibiting 130 cycle discharge/charge.
