A 3D graphene-supported MoS2 nanosphere and nanosheet heterostructure as a highly efficient free-standing hydrogen evolution electrode

摘要

Cross-distributed MoS _(2) nanospheres and nanosheets were uniformly deposited on a 3D graphene foam by a hydrothermal approach. Attributable to their synergistic effect, the as-fabricated free-standing electrodes display excellent electrocatalytic activity and outstanding cycling stability towards hydrogen evolution.
