- Abstract
This work primarily studies the crystallization condition of molybdenum disulfide (MoS) in MoS/graphene hybrids by a temperature-varying hydrothermal method from 150 to 240 °C. Flower-like MoS nanoflakes were successfully grown on graphene nanosheets and characterized to understand the temperature-dependent crystallization process and the electrochemical performance. The highest electrocatalytic efficiency for both the dye-sensitized solar cell and the hydrogen evolution reaction was obtained by preparing the hybrid at 180 °C, which benefits from balanced high reactivity and high conductivity. This research leads to a better understanding of temperature dependence of MoS crystallization and offers guidelines for better catalytic material design.
