“…Doping TMDs with metals such as Cu, Ni, Co, Fe, Pt, Mn, Ru, Gd, etc. enhance the electrical conductivity and activate the basal planes of TMDs, leading to improved performance of supercapacitors. − For instance, Prakash et al prepared vertically aligned Ni-doped MoS 2 with enhanced interlayer spacing by a simple hydrothermal technique . The produced supercapacitor electrode with 6% Ni-doping in MoS 2 functioned exceptionally well with a high specific capacitance of 528 F g –1 at a current density of 1 Ag –1 , and a capacity retention up to 85% after 10 000 cycles.…”

Designing efficient and cost-effective materials is pivotal to solving the key scientific and technological challenges at the interface of energy, environment, and sustainability for achieving NetZero. Two-dimensional transition metal dichalcogenides (2D TMDs) represent a unique class of materials that have catered to a myriad of energy conversion and storage (ECS) applications. Their uniqueness arises from their ultra-thin nature, high fractions of atoms residing on surfaces, rich chemical compositions featuring diverse metals and chalcogens, and remarkable tunability across multiple length scales. Specifically, the rich electronic/electrical, optical, and thermal properties of 2D TMDs have been widely exploited for electrochemical energy conversion (e.g., electrocatalytic water splitting), and storage (e.g., anodes in alkali ion batteries and supercapacitors), photocatalysis, photovoltaic devices, and thermoelectric applications. Furthermore, their properties and performances can be greatly boosted by judicious structural and chemical tuning through phase, size, composition, defect, dopant, topological, and heterostructure engineering. The challenge, however, is to design and control such engineering levers, optimally and specifically, to maximize performance outcomes for targeted applications. In this review we discuss, highlight, and provide insights on the significant advancements and ongoing research directions in the design and engineering approaches of 2D TMDs for improving their performance and potential in ECS applications.

“…Jia et al 22 demonstrated the enhanced pseudocapacitive performance of a MoS 2 -based flexible SC by the codoping strategy of cations and anions, and the MoS 2 nanosheet arrays on carbon cloth were directly doped with N and Co atoms through a simple hydrothermal process. Hanifehpour et al 23 reported the effect of iron doping on the MoS 2 morphology, composition, and supercapacitor behavior, which were systematically investigated. However, there are inherent disadvantages that can be tackled.…”

As the demand for fuel continues to increase, the development of energy devices with excellent performance is crucial. Supercapacitors (SCs) are attracting attention for their advantages of high specific energy and a long cycle life. At present, the development of high-performance electrode materials is the main point for research and development of SCs. Transition metal sulfides have the advantages of a large interlayer space and high theoretical capacity, making them promising electrode materials. Herein, we reported a series of ultrathin mesoporous iron family element (Fe, Co, Ni) molybdenum disulfide (M x Mo 1−x S 2 /C, M = Fe, Co, and Ni) by a template method. The original monolayer mesoporous structure of MoS 2 /C was maintained, and accumulation and agglomeration of MoS 2 /C were avoided. Based on our investigations, the best performance was that of Co x Mo 1−x S 2 /C nanohybrids. Furthermore, the concentrations of Co and Mo ions were modulated to obtain the best performance, in which Mo and Co ions were released at 1:1, 1:2, and 1:3 ratios and they were named Co x Mo 1−x S 2 /C-1, Co x Mo 1−x S 2 /C-2, and Co x Mo 1−x S 2 /C-3, respectively. Overall, these materials represent a significant improvement and show promise as high-performance SC electrode materials due to their enhanced capacitance and stability. At a current density of 0.5 A g −1 , Co x Mo 1−x S 2 /C-2 has the optimal specific capacitance of 184 F g −1 . Co x Mo 1−x S 2 /C-2 as an SC electrode exhibited better reversible capacity and cycling stability than MoS 2 /C, which is an improvement over MoS 2 /C regarding reversible capacity and cycling stability.

“…in the MoS 2 layer can ameliorate the specific capacitance because of the improved electrochemical activity and abundant redox reactions originating from metallic heteroatoms. [12][13][14][15][16] Sun et al 17 fabricated Co-doped MoS 2 nanosheets, which achieved a capacity of 510 F g À1 at 1 A g À1 . Singha et al 18 prepared Mn incorporated MoS 2 nanoflowers using manganese chloride as a dopant, and appropriately Mn doped MoS 2 nanoflowers exhibited a maximum capacity of 430 F g À1 .…”
