MoS2-based nanocomposites: synthesis, structure, and applications in water remediation and energy storage: a review

Abstract

The world is currently facing critical water and energy issues due to the growing population and industrialization, calling for methods to obtain potable water, e.g., by photocatalysis, and to convert solar energy into fuels such as chemical or electrical energy, then storing this energy. Energy storage has been recently improved by using electrochemical capacitors and ion batteries. Research is actually focusing on the synthesis of materials and hybrids displaying improved electronic, physiochemical, electrical, and optical properties. Here, we review molybdenum disulfide (MoS2) materials and hybrids with focus on synthesis, electronic structure and properties, calculations of state, bandgap and charge density profiles, and applications in energy storage and water remediation.

Graphene-reinforced nanocomposites: synthesis, micromechanics models, analysis and applications – a review

“…Other factors like their porous microstructure, being stable electrochemically as well as having good stability mechanically are some merits of Gr-NCs when used as energy storage devices. 29,216 Gr-NCs are largely used in the electrodes of supercapacitors. Nowadays, Gr-NCs are widely used in producing renewable energy and photo/light-based energy applications.…”

Engineered magnetic oxides nanoparticles as efficient sorbents for wastewater remediation: a review

“…The most obvious properties are their stability, para-/ferrimagnetism, and environmental-friendly nature. They also should have a higher surface area, narrow bandgaps for higher visible light activity, and an unambiguous ability to absorb heavy metals (Abdel Maksoud et al 2021c;Singh et al 2019b;Bhateria and Singh 2019;Gusain et al 2019). Although iron oxides exist naturally, they can also be synthesized and fabricated via many routes such as co-precipitation (de Mello et al 2019), hydrothermal (Phumying et al 2021), sol-gel (de Oliveira Guidolin et al 2021, and solvothermal (Medinger et al 2021).…”

Electrodeposition of Molybdenum Disulfide (MoS2) Nanoparticles on Monocrystalline Silicon

“…Different forms of active HER MoS 2 electrocatalysts have been developed, including crystalline nanoparticles, amorphous films and molecular clusters [ 1 , 3 , 6 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. MoS 2 is also characterized by unique photocatalytic properties [ 3 , 6 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ]. This is due to the fact that S-Mo-S coordination in the crystal lattice generates unsaturated Mo and S atoms at the edges, resulting in highly active sites to perform H 2 production via water splitting [ 3 , 6 , 17 , 28 , 29 , 32 , 37 ].…”

In order to enhance the photocatalytic activity of MoS 2 nanostructures, it is possible to couple them with semiconductors that enable rapid charge generation and reduce the combination rate of photoinduced electron-hole pairs [ 6 ].…”
