“…Pt/C-MnxO1+x [32] and H3PMo12O40-Pt/reduced graphene oxide [33] were found to have better performance than Pt/C and PtRu/C due to the synergetic effects between Pt nanoparticles and hybrid supports. Wu et al synthesized a conductive copolymer based on indole-6-carboxylic acid and 3,4-ethylenedioxythiophene (EDOT) as the support for Pt particles [34].…”

“…The carbon sp 2 hybridization at a binding energy (BE) of 284.81 eV is more intense than its sp 3 counterpart at BE = 286.20 eV. Several carbon species that can be ascribed to an rGO structure [52,53] are displayed after deconvolution: C=C, CÀ C, CÀ O, C=O, OÀ C=O. Among them, the highest concentration is that of the C=C bonds, with 57.05 at.…”

An efficient route to chemically functionalize reduced graphene oxide (rGO) with ruthenium organometallic compounds and the subsequent anchorage of Pt nanoparticles is reported. Two organometallic complexes, [(η6‐C6H5OCH2CH2OH) RuCl2]2 (Ru‐dim) and [(η6‐C6H4(CHMe2)Me)RuCl2]2 (Ru‐cym), as well as commercial RuCl3 ⋅ XH2O (Ru‐com) have been synthetized an used as functionalizing agents. By implementing a conventional polyol synthesis method, the Pt/rGORu‐dim, Pt/rGORu‐cym, Pt/rGORu‐com and Pt/rGO nanocatalysts have been synthetized. Characterization by XRD indicates that the presence of Ru leads to the formation of Pt−Ru alloyed phases due to overlapping of Pt fcc and Ru hcp reflections. When characterized for the methanol oxidation reaction (MOR) in acid media, Pt/rGORu‐dim reached a mass current density of 491.49 mA mgPt−1, higher than those generated by the other nanocatalysts. The results show that the functionalization of rGO with Ru‐dim remarkably increases the catalytic activity of Pt for the MOR, suggesting Pt−Ru metal−metal interactions that promotes the anodic reaction.

“…The highly dispersed VO x nanoparticles (NPs) were found to be highly efficient for the hydroxylation of benzene. As one of the most interesting solid materials, carbon materials (such as activated carbon, MWCNTs, and graphene) can act as catalysts by themselves [25][26][27] or serve as supports for other active phase [28][29][30][31][32]. Nowadays, the vanadium oxide/carbon composites have attracted increasing attentions.…”

Abstract:The vanadium oxide/reduced graphene oxide (VO x /RGO) composites have been prepared by a simple solvothermal method with the assistance of cationic surfactant cetyltrimethylammonium bromide (CTAB). The microstructure and morphology of the resultant VO x /RGO composites have been well characterized. The VO x nanoparticles are highly dispersed on the RGO sheets with a particle size of about 25 nm. When used as hydroxylation catalysts, the VO x /RGO composites are more efficient than individual RGO and vanadium oxide catalysts. The enhanced catalytic performance may be related to not only the well dispersed VO x active species, but also the hydrophobic surface and huge π-electron system of RGO for the adsorption and activation of benzene. In addition, the effects of calcination conditions on the microstructure and catalytic properties of VO x /RGO composites have also been investigated. The uniform VO x nanoparticles on the separated RGO sheets show highly efficient catalytic performance, while the formation of aggregated H x V 2 O 5 and bulk V 2 O 5 species along with the destruction of RGO sheets are poor for the hydroxylation of benzene. Up to 17.4% yield of phenol is achieved under the optimized catalytic reaction conditions.
