▎ 摘　　要

We successfully loaded different quantities of MoS2 nanoflowers (MoS2-NF) into three-dimensional graphene aerogel skeleton (GA) by hydrothermal and freeze-drying process. The prepared MoS2 nanoflowers/graphene hybrid aerogels (denoted as MoS2-NF/GA) exhibit a gradually decreasing initial overpotential and Tafel slope with increasing of MoS2-NF, indicating a gradually improvement of HER performance. The enhancement may be explained by the benefit from excellent conductivity of GA to the acceleration of electrons transferring and the increased MoS2 active sites ascribed from the highly dispersed distribution of MoS2-NF in the GA. This study provides a method for loading controllably nanomaterials into three-dimensional graphene aerogel skeleton and a strategy for enhancing HER performance of MoS2-NF.
