Synthesis of MoS2/RGO Composites

Check if the same lab product or an alternative is used in the 5 most similar protocols
Ammonium molybdate [(NH4)6Mo7O24·4H2O], thiourea (CH4N2S), and ethanol (C2H6O), analytical reagents, were purchased from Sinopharm Chemical Reagent Co., Ltd. H2O2 (30%) was purchased from Aladdin Reagent Co., Ltd. Graphene Oxide (GO) was synthesized from natural flake graphite (100 mesh) by Hummers method [39 (link),40 (link)]. The preparation process of the MoS2/RGO composites can be summarized as follows. Amounts of, 1, 0.5, 0.33 mmol (NH4)6Mo7O24·4H2O and 30, 15, 10 mmol CH4N2S were dissolved in 35 mL diluted graphene solution, respectively, and stirred for 30 min to make them homogeneous. The three solutions were then transferred into three 45 mL polytetrafluoroethylene (PTFE) stainless steel autoclaves and maintained at 180 °C for 24 h. As shown in Figure 1, the raw materials for synthesis of MoS2 adsorbed on RGO first nucleate at high temperature to form MoS2 nanocrystals, and then form MoS2/RGO composites. Finally, the reaction system was cooled to room temperature naturally, the product was collected by centrifugation, washed with deionized water, and the sample preparation was concluded after drying for 20 h at 70 °C. For the convenience of description, the MoS2/RGO composites from 1, 0.5, 0.33 mmol (NH4)6Mo7O24·4H2O and 30, 15, 10 mmol CH4N2S were designated as MoS2/RGO-1, MoS2/RGO-2 and MoS2/RGO-3.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
