Carbon nanomaterials with lowdimensional nanostructure possess superior properties and promising applications. This paper provides a brief review of recent progress of carbon nanomaterials research in Institute of LowDimensional Carbons and Device Physics, Shanghai University. We are successful in massproduction and applications of highpurity and highcrystallinity singlewalled carbon nanotubes (SWCNTs) and doublewalled CNTs (DWCNTs) by hydrogen arc discharge. Highquality multiwalled CNTs (MWCNTs) with onedimensional quantum confinement effect, and the controlled growth of carbon nanowires have been prepared successfully. Electrochemical characteristics of graphene evaluated in cointype cells versus metallic lithium, and the Raman spectra of individual MWCNT or carbon nanowire have been studied. The future trend of carbon nanomaterial development is discussed.
