Electrochemically enhanced metal-support interaction of highly dispersed Ru nanoparticles with a CeO2 support

[Display omitted] •Low particle size Ru nanoparticles were deposited on CeO2 interfaced with YSZ.•Both positive and negative polarization showed pronounced effect for C2H4 oxidation.•Electroreduction of Ce4+ to Ce3+, caused stronger interaction with Ru.•Partial reduction of Ce4+ was supported by XPS...
