文摘

In this study, carbon nanofibers (CNFs) have been synthesized by a simple pyrolysis of tetrahydrofuran using molten zinc chloride as a liquid environment at 600 °C for 10 h. Scanning electron microscope images reveal that the obtained CNFs have diameters of about 50 nm and lengths up to tens of micrometers. As an anode material for Li ion batteries, the obtained CNFs can deliver a reversible capacity of 310 mA h/g after 200 cycles at a current density of 100 mA/g. When tetrahydrofuran is substituted by other carbon sources (ferrocene or lactic acid), CNFs can also be synthesized through this similar process; therefore, the pyrolysis method is a general way to prepare CNFs in molten zinc chloride.
