Highly Water-Soluble MoS2 and Encapsulated C60 with Ionic-Liquid Cyclodextrin Derivative Towards Improvement of Photocatalytic Hydrogen Production |
| 초록 |
Photocatalytic hydrogen production performed in water by using transition-metal dichalcogenide (TMD) based-materials have emerged to be effective catalysts, for instance MoS2. However, TMD possesses poor solubility in water and low active area that led to low efficiency of hydrogen yield. Herein, we synthesized water-soluble MoS2/C60/ILCD hybrid. The composite consists of molybdenum disulfide (MoS2) and encapsulated fullerene (C60) by ILCD (ionic liquid cyclodextrin) which highly obtain dissolution in water due to the presence of an imidazolium cation and a phosphorylated cyclodextrin anion. ILCD as a hydro-solubilizing reagent for C60 enhances the solubility than that with non-substituted CD and without of 2.8-fold and 107 -fold respectively. The proposed encapsulated C60 also provides a good exfoliation of MoS2 during physical synthesis, which was proven by XRD and Raman characterization. Furthermore, hydrogen production performance will be conducted. |
