Herein,we reported a one-step synthesis of carbon nanorods (CNRs) from renewable α-Cyclodextrin (α-CD) using a novel salt segregation strategy that exploits the self-assembly nature of α-CD in solution.The synthesis differed from the traditional template method in that it was characterized by segregation and protection by salt crystallization,the carbonization did not need the passage of protective gas,and the salt could be recovered after filtration.Therefore,this method was very cost-effective and did not cause environmental pollution.In addition,the diameters and lengths of the synthesized CNRs could be controlled by simply adjusting the α-CD concentration to control the aggregate sizes as needed,thus realizing CNRs with adjustable lengths in the range of 600～1500nm and adjustable diameters in the range of 50～80nm,with a maximum length-to-diameter ratio of up to 18.75.This work provided a simple new approach for the green preparation of carbon nanomaterials.
