Abstract Single porous In 2 O 3 nanosheets and In 2 O 3 /C nanosheet composite with double phases of c-In 2 O 3 and rh-In 2 O 3 were fabricated by a facile one-step solvothermal treatment of a mixture of d -fructose and In(NO 3 ) 3 using urea as a precipitating agent in water–ethanol mixed solution followed by calcination. The effect of solution on the fabrication of In 2 O 3 nanosheets was investigated and a possible mechanism was proposed to explain the formation of nanosheets. In 2 O 3 /C nanosheet composite electrode exhibited a high lithium storage capacity of 869 mAh g −1 after 100 cycles at 100 mA g −1 , excellent rate and long-term cycling performance. The superior electrochemical performance could be ascribed to the incorporation of carbon and the unique nanosheet architecture of the nanocomposite.
