Abstract

A novel cellulose substance (ordinary laboratory filter paper) derived hierarchical carbon/tin-oxide/molybdenum-dioxide (carbon@SnO2@MoO2) ternary nanoarchitectonic was fabricated by the self-assembly process and subsequent carbonization treatment. The resultant nanocomposite was composed of thin tin oxide layer sandwiched between the porous carbon nanofibers and the external molybdenum dioxide coating layer, where the thickness of the molybdenum dioxide coating layer was controlled facilely. As being utilized as an anodic material for lithium-ion batteries, the nanocomposite displayed high reversible capacity and good rate performance that are superior to those of the carbon@MoO2 hybrid without SnO2. The good electrochemical performance of the anode was benefited from the sophisticated multi-level structures of the composite, small sizes of the tin oxide (ca. 5 nm) and molybdenum dioxide (ca. 6 nm) nanocrystallites contained therein, and the synergistic interactions between the tin oxide layer, the outer molybdenum dioxide coating layers, as well as the porous carbon buffering matrix. For such a composite with MoO2 and SnO2 contents of 20 and 10%, respectively, by weight, it delivered a specific capacity of 608.1 mAh g−1 after 100 discharge/charge cycles at the current rate of 100 mA g−1. The current work presents a facile and cost-effective pathway to synthesize bio-substance derived nanocomposite materials for energy applications.
