A facile way to prepare graphene-supported Ru catalysts was developed here. For the first time, functionalized graphene obtained from thermal exfoliation of graphite oxide at low temperature (200°C) under air atmosphere was used to support Ru nanoparticles (2.3nm) with the simple method of incipient wetness impregnation. Heat treating at 700°C in N2 flow did not change the mean size but made Ru nanoparticles...
For the purpose as stated in title, three Ru catalysts were prepared with the same treated carbon nanotubes. One has most of Ru nanoparticles confined inside the channels, and the other two have most of Ru nanoparticles outside through different preparation methods. Heat treating was performed to obtain another three catalysts. Characterization by X-ray photoelectron spectroscopy indicated that heat...
