▎ 摘　　要

There is great interest in new materials that synergistically combine properties of reduced graphene oxide (rGO) with nanoparticles (NP) generating rGO-nanoparticles hybrid materials (NPHM). Based on the modified polyol process (MPP), we developed a new and versatile method to synthesize rGO and rGO-NPHM in one-pot route. rGO sheets with small defects number were reduced from graphene oxide by the MPP, and experimental parameters were varied to evaluate the method robustness, and adjusted to prepare rGO-NPHM, for instance, rGO/Au, rGO/Ag, rGO/CdSe, rGO/FePt and rGO/Fe3O4 inferring the versatility of our methodology. NPHM were evaluated by X-ray diffraction, transmission electron microscopy, vibrating sample magnetometry, and Raman, UV-Vis, and FTIR spectroscopies. All synthesized NPHM shown size-controlled monodisperse-like NP homogeneously distributed onto the rGO sheets, except for the Ag-NP where a bimodal size distribution was observed. Plasmon (rGO/Au and rGO/Ag) and typical absorption and emission (rGO/CdSe) by UV-Vis, whereas paramagnetic-like (rGO/FePt) and superparamagnetic (rGO/Fe3O4) behavior was observed by the magnetic NPHM. The MPP is already efficient for NP preparation and here, we showed that its might successful for rGO and rGO-NPHM synthesis in a simple and versatile one-pot route, which can be scaled up to allow mass production and easily tuned for other NP kinds.
