“…On the other hand, the in-situ the synthesis process involves ionic reactions such as sol-gel [17], solvothermal [18] or hydrothermal [19] methods that hold capability of synthesis nanoscale materials with uniform dispersion and complex architectures. Although hydrothermal strategies are widely used for the preparation of MoS 2 /graphene materials, the reported methods often require long reaction time from several hours to several days [19][20][21][22][23][24][25][26][27] as shown in Table 1. Therefore, there is still a huge challenge to develop fast simple, reliable and economical synthetic routes for preparing MoS 2 /graphene composites.…”

In this report, thin layers of MoS 2 were in-situ incorporated into graphene oxide (GO) to form MoS 2 /graphene nanocomposite by a facile ultrasonic-assisted hydrothermal method. Xray Diffraction (XRD) and Raman analysis revealed that the as-synthesized MoS 2 nanosheets crystalized in hexagonal phase 2H-MoS 2 while High Resolution Transmission Electron Microscopy (HRTEM) images confirmed that MoS 2 layers with average thickness of ~5-6 nm (6-8 layers) attached on the edges and surfaces of graphene sheets with high density and uniform shape restacking in three-dimensional (3D) architectures. The Scanning Transmission Electron Microscopy -Energy Dispersive X-ray spectrum (STEM-EDX) investigation further confirmed the low impurity of MoS 2 /graphene composite, and the well repairing of defects in GO surfaces during the hydrothermal process. Our approach is promising for a scalable, inexpensive, and accurate strategy to fabricate state-of-the-art materials with a certain structure for various practical applications such as electrode material for Lithium battery or supercapacitor.

Nanotechnology is considered one of the paramount forefronts in science over the last decade. Its versatile implementations and fast-growing demand have paved the way for innovative measures for the synthesis of higher quality nanomaterials. In the early stages, traditional synthesis methods were utilized, and they relied on both carcinogenic chemicals and high energy input for production of nano-sized material. The pollution produced as a result of traditional synthesis methods induces a need for environmentally safer synthesis methods. As the downfalls of climate change become more abundant, the scientific community is persistently seeking solutions to combat the devastation caused by toxic production methods. Green methods for nanomaterial synthesis apply natural biological systems to nanomaterial production. The present review highlights the history of nanoparticle synthesis, starting with traditional methods and progressing towards green methods. Green synthesis is a method just as effective, if not more so, than traditional synthesis; it provides a sustainable approach to nanomaterial manufacturing by using naturally sourced starting materials and relying on low energy processes. The recent use of active molecules in natural biological systems such as bacteria, yeast, algae and fungi report successful results in the synthesis of various nanoparticle systems. Thus, the integration of green synthesis in scientific research and mass production provides a potential solution to the limitations of traditional synthesis methods.

“…Song et al presented a synthesis method of MoS 2 nanosheets on rGO surface by a one-step hydrothermal growth technique. MoS 2 /rGO materials showed excellent electrochemical performance for Na-ion batteries [ 39 ]. Similarly, Murugan et al deposited MoS 2 nanosheets on rGO by an in situ hydrothermal method, resulting in MoS 2 /rGO materials consisting of a few-layered MoS 2 structures with abundantly exposed edges stacked onto rGO [ 40 ].…”

Molybdenum disulfide (MoS2) can be an excellent candidate for being combined with carbon nanomaterials to obtain new hybrid nanostructures with outstanding properties, including higher catalytic activity. The aim of the conducted research was to develop the novel production method of hybrid nanostructures formed from MoS2 and graphene oxide (GO). The nanostructures were synthesized in different weight ratios and in two types of reactors (i.e., impinging jet and semi-batch reactors). Physicochemical analysis of the obtained materials was carried out, using various analytical techniques: particle size distribution (PSD), thermogravimetric analysis (TGA), FT-IR spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM). Due to the potential application of materials based on MoS2 as the catalyst for hydrogen evolution reaction, linear sweep voltammetry (LSV) of the commercial MoS2, synthesized MoS2 and the obtained hybrid nanostructures was performed using a three-electrode system. The results show that the developed synthesis of hybrid MoS2/GO nanostructures in continuous reactors is a novel and facile method for obtaining products with desired properties. The hybrid nanostructures have shown better electrochemical properties and higher onset potentials compared to MoS2 nanoparticles. The results indicate that the addition of carbon nanomaterials during the synthesis improves the activity and stability of the MoS2 nanoparticles.
