چکیده انگلیسی
Inspired by hierarchical structures of natural species, we developed a facile and inexpensive approach to synthesize a novel hierarchical modified porous carbon/graphene (MPC/RGO) composite material. The porous carbon was obtained from sugarcane bagasse and later combined with reduced graphene oxide by using a hydrothermal method to produce the MPC/RGO. The obtained MPC/RGO composite was characterized by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). As an anode for lithium-ion battery, it delivers a high reversible discharging capacity of 617.3Â mAh gâ1 after 600 cycles at a current density of 200Â mAÂ gâ1, which is significantly higher than 272.5Â mAh gâ1 of the mechanical mixture of the modified porous carbon (MPC) and RGO at the same testing condition. This impressive electrochemical performance showed by the MPC/RGO composite is attributed to the chemical bonds formed between the reduced graphene oxide sheets and the hierarchical porous carbon. This simple synthesis approach and the high performance of the product is a dream combination in the development of novel and smart materials.
