摘要	Ru nanoparticles have been deposited onto a multi-walled carbon nanotube paper (Ru@MWCNTP) via a wet chemical method. The resulting catalyst, Ru@MWCNTP has been demonstrated to significantly reduce the charge overpotentials of the Li-O-2 battery at a current density of 500 mA g(-1). The reversible formation and decomposition of Li-2-O-2 can be revealed by X-ray diffraction (XRD). In the initial 20 cycles of discharge and charge, the Li-O-2 battery with Ru@MWCNTP presents a stable capacity of 5000 mA h g(-1) and an almost constant discharge-charge potential, contrasting with the quickly decaying capacity of the bare MWCNTP without the addition of Ru nanoparticles. The combination of the porous networks of the multi-walled carbon nanotubes (MWCNTs), which are beneficial for the facile transport of both electrons and oxygen, and the superior catalytic activity of Ru nanoparticles enables a good cycling performance and rate capability of the Li-O-2 battery.
