Hierarchical MoS_2 microboxes constructed by nanosheets with enhanced electrochemical properties for lithium storage and water splitting

摘要

Hierarchical MoS_2 microboxes constructed by ultrathin nanosheets are synthesized by a facile template-assisted strategy. The first step involves the L-cysteine assisted uniform growth of hierarchical MoS_2 nanosheets on MnCO_3 microcube templates which are at the same time converted to MnS. Hierarchical MoS_2 microboxes can be obtained by selectively dissolving MnS through acid washing. When evaluated as an anode material for lithium-ion batteries, the hierarchical MoS_2 microboxes manifest high specific capacity and excellent cycling performance. The hierarchical MoS_2 microboxes also show enhanced electrocatalytic activity for electrochemical hydrogen evolution from water.
