In this paper, nickel oxide/graphene aerogel composites (NiO/GA) have been synthesized by a simple solvothermal route starting with graphene oxide (GO). The morphology, composition and microstructure of the as-obtained samples are systematically characterized by Fourier Transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). Moreover,...
In recent years, modifying anode materials surfaces of Li2MnSiO4 become a popular pursuit. This paper reveals a fast sol-gel process that the Li2MnSiO4 in situ coated with carbon membrane prepared using liquid polyacrylonitrile (LPAN) as the carbon source. The structure and micro-morphology of the as-prepared Li2MnSiO4 and Li2MnSiO4/C nanocomposite were characterized by thermo-gravimetric analysis...
Working electrodes of dye-sensitized solar cells (DSSCs) were fabricated with a low temperature process using films composed of ZnO nanoparticles and multiwalled carbon nanotubes (MWNTs). The effects of concentration and surface modification of MWNT on device performance were investigated. The results indicate that the performance of DSSCs depended on the type and amount of MWNT used. The power conversion...
