Preparation of long linear carbon chain inside multi-walled carbon nanotubes by cooling enhanced hydrogen arc discharge method
Long linear carbon chains with sp hybridization inside multi-walled carbon nanotubes (LLCC@MWCNTs) can be prepared in the cathode deposits obtained by hydrogen arc discharge. In this work, a cooling system was introduced into the hydrogen arc discharge method to improve the growth yield of LLCC@MWCN...

| description | Long linear carbon chains with sp hybridization inside multi-walled carbon nanotubes (LLCC@MWCNTs) can be prepared in the cathode deposits obtained by hydrogen arc discharge. In this work, a cooling system was introduced into the hydrogen arc discharge method to improve the growth yield of LLCC@MWCNTs samples, as indicated by the corresponding stronger Raman peaks between 1780 cm-1 and 1880 cm-1, compared with conventional systems. Moreover, the cooling largely expanded the narrow scope of suitable conditions for the preparation of LLCC@MWCNTs, and high purity samples were easily produced. Qualitative analysis of arc discharge process helped conclude that cooling helps to increase the temperature of arc plasma, which is beneficial to improve both the growth yield of LLCC@MWCNTs and the purity of MWCNTs. This work provides a new approach to improve the growth yield of LLCC@MWCNTs and will benefit further studies and future applications of this new one-dimensional allotrope. |
