“…The energy density depends on the capacitance and the potential window by relation E ½CV 2 . Therefore, considerable efforts have been made to maximize "E" by enhancing "V" and "C." Among various types of electrochemical capacitors, 2D materials-based supercapacitors like graphene and MoS 2 , are gaining significant interest because of their intrinsic features, such as their high conductivity, low cost, flexibility, wide potential, window and fast redox reaction (Firmiano et al, 2014;Hao et al, 2014;Sun et al, 2015;Lv et al, 2016;Mehran and Baig, 2019;Muthu and Gopalan, 2019;Khan et al, 2020;Rani et al, 2020;Rathinamala et al, 2020;Zhao et al, 2021).…”

“…based MXene heterostructures with reference to interesting properties explored in transition metal sulfides in advanced energy storage applications. [ 43,222–226 ] For TMDs, in the form of MY 2 , where M is a transition metal and Y stands for the chalcogens, especially sulfur in MXene heterostructures, generally manifest exposed redox‐active surface areas with surface tunable attributes with rich redox‐active sites with capacitive and faradaic contributions. [ 224,227–229 ] Nevertheless, pristine TMD or metal sulfides (especially MoS 2 ) experience several shortcomings like as insignificant microstructural and chemical stability and integrity, noticeably poor electronic conductivity, paucity of efficient and high rate ion/charge transfer between electrode/electrolyte interfaces and inaccessible active surface sites that could be critically resolved by complementary material heterostructure organization.…”

2D interfacial heterostructures have found an unassailable status in energy storage systems, particularly in supercapacitors citing the intriguing structural and electrochemical characteristics. Exactly a decade ago, MXene, a promising 2D transition metal carbide/nitride/carbonitride was found to possess excellent conductivity, hydrophilicity, laudable charge storage opportunities, and enriched surface functionalities conducive for supercapacitors with inherent challenging shortcomings. To substantially improve, assembled 2D/2D MXene heterostructures exhibit commendable performance backed by the fact of swift increase in research interest. In this review, state‐of‐the‐art research progress in material design and electrochemical performance of 2D/2D MXene heterostructures for supercapacitors are investigated. Discussion is initially on MXene fundamentals including synthesis and energy storage governing properties. Particularly, different preparation including electrostatic assembly, in situ growth, hydrothermal treatment, and objective specific strategies and its implications are elaborated. Especially, the electrochemical interface science, electrode–electrolyte interaction and ion/electron dynamics and synergistic enhancement of MXene/rGO, MXene/LDH, MXene/metal sulfides and timely investigations on other 2D MXene architectures are provided for its compatibility from solid‐state to microsupercapacitors for commerciality. To conclude, a well‐comprehended outlook, key challenges, and prospective research guidelines stretching from fundamental mechanism investigations to material and electrolyte optimizations are presented to encourage advanced 2D MXene architectures for future generation supercapacitors.

“…Mischaracterization of MoS 2 as the 3R-MoS 2 polytype is often the result of misinterpreted XRD data. This error is most common in samples prepared by hydrothermal syntheses − but also occurs for samples obtained by a variety of procedures where disordered MoS 2 is synthesized. , Mischaracterization occurs when broadening of the 2H-MoS 2 10 ( = 1, 3 and 5) reflections are mistaken for the convolution of 104, 105, 107, and 108 reflections from crystalline 3R-MoS 2 onto the 2H-MoS 2 pattern . While this certainly could be the case (as in the 50:50 2H-MoS 2 :3R-MoS 2 mixtures simulated by Houben et al and Goloveshkin et al …”

Transition metal dichalcogenides (TMDs) of molybdenum and tungsten are layered van der Waals materials that exhibit a rich array of polytypes. The different possible arrangements of the constituents of the “two-dimensional” MX2 sheets (where M = group 4–10 elements, X = chalcogen) give rise to a host of interesting and tunable phenomena. Molybdenite, or molybdenum disulfide (MoS2) in its most abundant and thermodynamically stable form, 2H-MoS2, is perhaps the most widely used TMD, though the potential applications of its metastable polytypes have been recognized only recently. From among the polytypes, the 3R-MoS2 (rhombohedral) phase has attracted the most interest because of its thermodynamic stability, ABC stacking (as opposed to the AA′ of the more common 2H-MoS2), and lack of inversion symmetry. These properties make it an excellent candidate for photonics, optoelectronics, and catalysis. Because the literature on this material is rapidly expanding, this review seeks to summarize the history, known and predicted characteristics, syntheses, and applications, as well as common misconceptions of, and surrounding, 3R-MoS2. Although the review is chemically focused, it includes suggested reading to cover a broader scope.
