Abstract

Selenium modified ruthenium/reduced graphene oxide (RuSe/rGO) is explored as an electrocatalyst towards VO²⁺/VO₂⁺ redox couples in vanadium redox flow batteries. Compared with the rGO electrode, the RuSe/rGO can significantly alleviate the polarization and improve the reversibility of the redox reaction, by virtue of the excellent catalytic activity and electronic conductivity.
