Abstract
- A hierarchically nanotubular MoO3/SnO2 composite was synthesized based on the layer‐by‐layer self−assemble process followed by a calcination treatment, employing natural cellulose substance (commercial filter paper) as structural scaffold. This nanocomposite is composed of molybdenum trioxide nanocrystallites immobilized as a thin layer on the tin oxide nanotube surface. As being utilized as a host material for lithium storage, the MoO3/SnO2 nanocomposite exhibited high reversible specific capacity, good cyclability and enhanced rate performance as compared with the pure SnO2 and MoO3 counter materials. For the nanotubular MoO3/SnO2 composite with 48.9 wt% MoO3 content, it delivered an initial discharge capacity of 1930.6 mAh g−1 and a stable specific capacity of 1084.1 mAh g−1 after 100 discharge/charge cycles at a current density of 100 mA g−1. The excellent lithium storage performance of the MoO3/SnO2 composite is benefited from the sophisticated hierarchically three‐dimensional network structures and the synergistic interaction between MoO3 and SnO2 components upon repeated lithiation/delithiation processes. A cellulose templated nanotubular MoO3/SnO2 composite was synthesized based on a self‐assemble approach, which showed excellent lithium storage properties as being used as an anodic material for lithium‐ion batteries (see figure).
