What is Molybdenum Disulfide?

The Molybdenum Disulfide  of hydrogen by catalytic water splitting is important for many industries, including renewable energy petroleum refining and producing methanol and ammonia in the chemical industry. Within the renewable energy field, hydrogen is an attractive candidate for storing energy produced by intermittent renewable energy sources such as solar and wind. Hydrogen is an important chemical feedstock for refining petroleum to produce methanol and ammonia. Within the chemical industry, hydrogen produced from catalytic water splitting has a higher purity and a lower environmental impact than that produced by steam-methane reforming, currently the most common process used for hydrogen production. Despite its significant potential, the widespread adoption of catalytic water splitting has been delayed due to a lack of ideal catalysts with high performance and low cost.


2D–0D MoS2–quantum dots (QDs) heterostructures

Photodetectors fabricated with hybrid MoS2/PbS QDs yield significantly high photoresponsivity. 0D QDs have been used to improve the performance of MoS2 photodetectors. Huo et al. developed photodetectors by incorporating mercury telluride (HgTe) colloidal QD film into a TiO2-encapsulated few-layer MoS2 channel. In the MoS2/TiO2/HgTe hybrid heterostructure, TiO2 is a buffer layer between the MoS2 channel and the HgTe QD layer that acts as an electron-accepting medium to form a p–n junction with the HgTe QDs to facilitate the transfer of photogenerated charges from the HgTe QDs to the MoS2 channel. MoS2/TiO2/HgTe hybrid photodetectors showed a high photoresponsivity of 106 A W−1 under an incident power of 70 fW (0.35 μW cm−2) at a gate voltage (Vg) of −15 V and a Vds of 1 V, which is seven orders of magnitude higher than that of the HgTe QD photodetector due to the low carrier mobility (2 × 10−3 cm2 V−1 s−1) of the HgTe QDs.  


MoS2-2D van der Waals heterostructures (vdWHs)

MoS2-based photodetectors have been designed and developed using different electrode materials and van der Waals heterostructures (vdWHs) to improve their optoelectronic properties. The performance of MoS2-based photodetectors can be increased using rGO layers. Shows a schematic of the multilayer MoS2 photodetector developed with Mo bottom contacts (100 nm) on thermally oxidized SiO2/Si substrates (270 nm) and the photoresponsivity and EQE of the ML MoS2 photodetector measured over the 400–1100 nm spectral region, as reported by Saenz et al. The photodetector exhibited ultrahigh photoresponsivity of 1.4 × 104 A W−1 and detectivity of 2.3 × 1011 Jones at a 700 nm wavelength with a 14.5 pW laser power for the multilayer MoS2 device fabricated using 100 nm thick Mo bottom electrodes, with a broadband photoresponse from the UV to IR regime.
