Enhancing hydrogen evolution reaction (HER) performance by loading MoS2 nanoflowers into three-dimensional graphene aerogel skeleton

Different quantities of MoS2 nanoflowers (MoS2-NF) were loaded into three-dimensional graphene aerogel skeleton by hydrothermal and followed freeze-drying process. The three-dimensional rGO skeleton has the advantages of high specific surface area to increase the number MoS2 active sites and excellent conductivity beneficial to accelerate electron transfer, resulting in an improved HER performance.
