As the primary culprit of greenhouse effect, carbon dioxide has garnered global attention, and the technologies currently being developed to reduce the emission of CO2 vary widely. In this study, CO2 was electrochemically reduced in various molten mixtures of LiNaK carbonates to carbon nanomaterials. By regulating the electrolysis current density, electrolyte, and electrolytic temperature, the carbon...
Gold nanoparticle/graphene oxide hybrids (AuNP/GO) were easily fabricated by a redox reaction between GO and chloroauric acid without using any additional reductant and then used to stabilize Pickering emulsions. Factors affecting the properties of the emulsions were studied, including the HAuCl 4 /GO mass ratio used to prepare the AuNP/GO, the oil/water ratio, the AuNP/GO concentration, the...
A simple and environment-friendly method was used to prepare Pt/reduced graphene oxide (Pt/RGO) hybrids. This approach used a redox reaction between Na 2 PtCl 4 and graphene oxide (GO) nanosheets and a subsequent thermal reduction of the material at 200°C for 24h in a vacuum oven. In contrast to other methods that use an additional reductant to prepare Pt nanoparticles, the Pt ...
Pt–Cu/reduced graphene oxide (Pt–Cu/RGO) hybrids with different Pt/Cu ratios were prepared by the reduction of H 2 PtCl 6 and CuSO 4 by NaBH 4 in the presence of graphene oxide (GO). The Pt–Cu nanoparticles were characterized by transmission electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy. The reduction of GO was verified by ultraviolet–visible...
