“…The monolayer of MoS 2 , which is purely made of a honeycomb sheet of molybdenum atoms that are covalently sandwiched between two honeycomb sheets of sulfur atoms, is known to have a hexagonal plane of sulfur atoms on either side of a hexagonal plane of Mo atoms. 29,30 Aer geometric optimization using the uB97XD/6-311++G(d,p) level of theory, the geometrically optimized lattice parameters for the monolayer surface and its dopant before adsorption were observed to have the following bond lengths. For the boron-doped surface (B@MoS 2 -QD) the B 36 -Mo 13 , B 36 -Mo 4 and B 36 -Mo 15 bond lengths were 2.185 A, 1.851 A and 2.185 A, respectively.…”

“…Doping MoS 2 with heteroatoms can also modify the MoS 2 properties by regulating the electronic structure and conductivity, regulating the interlaying spacing, and increasing the number of active sites [ 102 , 103 , 104 ]. This type of modification has been shown to be effective in photocatalytic hydrogen production and battery fields [ 102 , 103 , 104 ]. Doping with metallic elements may lead to undesirable consequences, such as the reduction in stability of MoS 2 by promoting the formation of the MoS 3 phase.…”

The need for fresh and conveniently treated water has become a major concern in recent years. Molybdenum disulfide (MoS2) nanomaterials are attracting attention in various fields, such as energy, hydrogen production, and water decontamination. This review provides an overview of the recent developments in MoS2-based nanomaterials for water treatment via adsorption and photodegradation. Primary attention is given to the structure, properties, and major methods for the synthesis and modification of MoS2, aiming for efficient water-contaminant removal. The combination of MoS2 with other components results in nanocomposites that can be separated easily or that present enhanced adsorptive and photocatalytic properties. The performance of these materials in the adsorption of heavy metal ions and organic contaminants, such as dyes and drugs, is reviewed. The review also summarizes current progress in the photocatalytic degradation of various water pollutants, using MoS2-based nanomaterials under UV-VIS light irradiation. MoS2-based materials showed good activity after several reuse cycles and in real water scenarios. Regarding the ecotoxicity of the MoS2, the number of studies is still limited, and more work is needed to effectively evaluate the risks of using this nanomaterial in water treatment.

“…The 3D structure is theoretically beneficial to expose more anchoring sites of LiPSs. Besides, the 3D structure provides sufficient deposition space for insoluble Li 2 S 2 and Li 2 S, avoiding the insulating nature to block the transmission path of lithium ions. − For example, Luo et al designed 3D porous FeP/rGO microspheres supported on a commercial separator to provide strong adsorption toward LiPSs . Niu’s group introduced 3D hollow nanospheres (MoP@C/N) on the separator as an outstanding immobilizer to inhibit LiPSs diffusion .…”

Lithium sulfur batteries (LSBs) are regarded as one of the most promising energy storage devices due to the high theoretical capacity and energy density. However, the shuttling lithium polysulfides (LiPSs) from the cathode and the growing lithium dendrites on the anode limit the practical application of LSBs. To overcome these challenges, a novel three-dimensional (3D) honeycombed architecture consisting of a local interconnected Co3O4 successfully assembled into a scalable modified layer through mutual support, which is coated on commercial separators for high-performance LSBs. On the basis of the 3D honeycombed architecture, the modified separators not only suppress effectively the “shuttle effects” but also allow for fast lithium-ions transportation. Moreover, the theoretical calculations results exhibit that the collaboration of the exposed (111) and (220) crystal planes of Co3O4 is able to effectively anchor LiPSs. As expected, LSBs with 3D honeycombed Co3O4 modified separators present a reversible specific capacity with 1007 mAh g–1 over 100 cycles at 0.1 C. More importantly, a high reversible capacity of 808 mAh g–1 over 300 cycles even at 1 C is also acquired with the modified separators. Therefore, this proposed strategy of 3D honeycombed architecture Co3O4 modified separators will give a new route to rationally devise durable and efficient LSBs.
