Abstract

Two Dimensional (2D) material has attracted much interest in material science field. 2D material such as Molybdenum Disulfide (MoS2) is such a promising material due to its structure provided absorption sites as well as shorter diffusion path, but restacking of MoS2 sheets affect its functional properties which therefore resulting with low efficiency in the device. A strategy has been proposed which is to compose MoS2 with MXene material to form a hybrid material. 2D MXene can host many different cations between its layers and also it has good electrical conductivity. Its special properties have attracted attention from various field. In this study, the MXene/MoS2 hybrid material and electrodes have been synthesized and fabricated at first by applying the conventional slurry coating technique. Followed by the X-ray Diffraction which showed the the hybrid material with crystalline structure and successfully composited between both MXene and MoS2. Furthermore, critical review has been conducted on Raman Spectroscopy which led to an expectation result of MXene/MoS2 hybrid material to have a good crystalline quality as less structural defects and also on Scanning Electron Microscopy which in expectation to have greater surface area that leads to better performance. Later, its electrochemical performances in testing such as Cyclic Voltammetry and Galvanostatic Charge-Discharge in aqueous electrolyte were evaluated. It was found that the highest specific capacitances as achieved in this study were 15.736Fg-1 and 1.36Fg-1 which attributed to hybrid composition of 40:40 MXene/MoS2 in respecting to cyclic voltammetry and galvanostatic charge-discharge. The results indicated 40:40 MXene/MoS2 hybrid as the most optimal sample at which MXene material is believed as a positive factor in assisting its capacitive performance, thus suggesting its potential in energy storage application.
