Abstract:
In this study, we first focus on effects of PVA surfactant on Li2Fe0.5Mn0.5SiO4/C by using X-ray diffraction, Fourier transform infrared spectroscopy, micro Raman analysis, scanning electron microscope, transmission electron microscope and magnetization measurements. XRD result reveals the formation of new phase (Li2Fe0.5Mn0.5SiO4/C), as a result of embedded carbon, intensity of the peaks was also suppressed. Intensity domination of G-band in micro Raman analysis affirmed that the establishment of graphene formation which was yielded from decomposition of organic materials of both PVA and acetate. Confirmation of Si-O and Si-C bond in the as-prepared material was made by FTIR analyses. A well uniform spherical shaped morphology was observed in both SEM and TEM images. In addition, the TEM picture further demonstrates Li2Fe0.5Mn0.5SiO4/C with average particle size of about 20 nm by PVA introducing.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
