abstract = {In this study, we present the facile formation of platinum
nanoparticles (Pt-NPs) on reduced graphite oxide (rGO)
(Pt-NP@rGO) by microwave-induced heating of the
organometallic precursor ((MeCp)PtMe3 in different tunable
aryl alkyl ionic liquids (TAAIL). In the absence of rGO,
transmission electron microscopy (TEM) reveals the formation
of dense aggregates of Pt-NPs, with primary particle sizes
of 2 to 6 nm. In contrast, in the Pt-NP@rGO samples, Pt-NPs
are homogeneously distributed on the rGO, without any
aggregation. Pt-NP@rGO samples are used as electrode
materials for oxygen reduction reaction (ORR), which was
assessed by cyclic voltammetry (CV) and linear sweep
voltammetry (LSV). The electrochemical surface area (ECSA)
and mass-specific activity (MA) increase up to twofold,
compared with standard Pt/C $60\%,$ making Pt-NP@rGO a
competitive material for ORR.},
