Iron-based anodes for lithium-ion batteries(LIBs)with higher theoretical capacity,natural abundance and cheapness have received considerable attention,but they still suffer from the fast capacity *** address this issue,we report a facile synthesis of plate-like carbonsupported Fe_(3)C nanoparticles through chemical blowing/carbonization under *** ultrafine Fe_(3)C nanoparticles are prone to be oxidized when exposing in air;thus,Fe_(3)C/C with mild oxidization and the fully oxidized product of Fe_(2)O_(3)/C are successfully prepared by controlling the oxidization *** applied as an anode material in LIB,the Fe_(3)C/C electrode demonstrates excellent cycle stability(826 mAh·g^(-1)after 120 cycles under 500 mA·g^(-1))and rate performance(410.6 mAh·g^(-1) under 2 A·g^(-1)),compared with the Fe_(2)O_(3)/C *** enhanced electrochemical performance can be ascribed to the synergetic effect of the Fe_(3)C with mild oxidation and the unique hierarchical structure of plate-like carbon decorated with Fe_(3)C *** importantly,this work may offer new approaches to synthesize other transition metal(e.g.,Co,Ni)-based anode material by replacing the precursor ingredient.

A Convenient Method for the oxidation of Alcohols with KMnO_4 to Their Corresponding Carbonyl Compounds in Ionic Liquid Media

引用

复旦学报（自然科学版） 2007年第5期46卷 596-页

作者： J.Safaei-Ghomi A.R.Hajipour A.H.Bamoniri M.Esmaeili Chemistry Department Kashan University Chemistry Department Isfahan University of Technology

1 Results Carbonyl compounds constitute an important group of molecules in organic chemistry,which appears in pharmaceuticals,dyes and industrially important chemicals[1-2].The oxidation of alcohols to the corresponding carbonyl groups is a fundamental transformation in organic chemistry and industrially important[3].There is considerable interest in the use of room temperature ionic liquids as promising substitutes for volatile organic *** ambient-temperature ionic liquids,especially those bas...
