摘要

Crude protein-containing reed catkins with a natural tubular structure are employed as a carbon precursor to prepare porous nitrogen-doped carbon tubes (PNCTs) by ZnCl2 activation. The obtained PNCTs, with a large specific surface area of 1751.1 m(2) g(-1) and satisfactory N-content of 4.22 wt%, exhibit a super-high specific capacity of 2016.3 mA h g(-1) at 0.02 A g(-1), and an excellent cycling stability of 512.4 mA h g(-1) after 500 cycles at 1 A g(-1), as an anode material for lithium ion batteries (LIBs).
