“…In addition, constructing ultrathin, hollow, or hierarchical nanostructures and extending layer spaces may greatly shorten the electron/matter transport path. [159,234,235] Moreover, by forming heterostructures with highly conductive materials such as metal or Gr, not only can the poor conductivity of MoS 2 be improved, but restacking can also be inhibited to some extent. In the long run, the preparation of MoS 2 single crystals relies too much on CVD method, which is the biggest challenge for its industrial application in biosensors.…”

The disulfide compounds of molybdenum (MoS 2 ) are layered van der Waals materials that exhibit a rich array of polymorphic structures. MoS 2 can be roughly divided into semiconductive phase and metallic phase according to the difference in electron filling state of the 4d orbital of Mo atom. The two phases show completely different properties, leading to their diverse applications in biosensors. But to some extent, they compensate for each other. This review first introduces the relationship between phase state and the chemical/physical structures and properties of MoS 2 . Furthermore, the synthetic methods are summarized and the preparation strategies for metastable phases are highlighted. In addition, examples of electronic and chemical property designs of MoS 2 by means of doping and surface modification are outlined. Finally, studies on biosensors based on MoS 2 in recent years are presented and classified, and the roles of MoS 2 with different phases are highlighted. This review offers references for the selection of materials to construct different types of biosensors based on MoS 2 , and provides inspiration for sensing performance enhancement.

properties [4][5][6][7] and are also demonstrating broad application potentials in the energyrelated fields, [8][9][10][11][12][13][14][15][16][17][18] electronic devices, [19][20][21][22] and molecular chemistries. [23,24] Notably, the scalable synthesis of 2D TMDCs is an essential prerequisite, and considerable efforts have also been made, including mechanical/chemical exfoliation, [25,26] wet chemical synthesis, [27][28][29][30] ion intercalation, [31][32][33][34] and chemical vapor deposition (CVD). [35][36][37][38] However, some bottlenecks have been proposed for these approaches, such as complex growth processes, highcost, low-yield, and environmental pollution. In this regard, it is highly desirable to develop a scalable and high-efficiency method to synthesize 2D TMDCs with a high yield.As a kind of high-efficient and clean secondary energy, H 2 is emerging as a splendid alternative for fossil fuels due to its high energy density and zero carbon emission. [39] Recent years have witnessed revolutionary progress in exploiting electrocatalysts for hydrogen/oxygen evolution reactions (HER/OER). [3,40] Nevertheless, in consideration of the incompatible activity over different pH ranges, the excellent HER and OER performances are not obtained in the same electrolytes for the most of reported electrocatalysts. [41] In addition, the development of OER is sluggish and consumes a mass of electricity input producing relatively low-value products. [42] It is thus highly urgent to explore new electrocatalysts for reducing electricity consumption and enhancing the H 2 evolution. Interestingly, the sulfion oxidation reaction (SOR) is much more thermodynamically favorable than OER in view of the fact that the S 2− is more prone to offer electrons. [43] Therefore, the electrocatalytic SOR should be investigated as the alternative of OER for the H 2 evolution by coupling with cathodic HER. Moreover, as a kind of toxic by-product in the industrial production, the S 2− should be removed or recycled. [44] However, the SOR performances of most of the reported electrocatalysts are still unsatisfactory.To tackle such issues, we design a high-throughput, highyield, and low-temperature strategy for the direct synthesis of 2D VSe 2 nanosheets and SnSe 2 nanoflowers, respectively. This provides us with an opportunity for the exploration of energy applications. In particular, a plentiful of wrinkles and unique hierarchical structures are observed in ultrathin VSe 2 nanosheets and SnSe 2 nanoflowers, respectively, which offerThe electrocatalytic sulfion (S 2− ) recycling and hydrogen (H 2 ) evolution play indispensable roles in converting waste into sustainable energy and boosting hydrogen economy. However, the development of such promising technologies is hindered by the lack of electrocatalysts with low-cost, high-efficient, and robust stability. 2D VSe 2 and SnSe 2 hold great application potentials in the energy-related fields yet face daunting challenges in terms of large-scale synthesis. Herein, a gram-scale and high-yield strate...

Creating nanosized pores in layered materials can increase the abundant active surface area and boost potential applications of energy storage devices. Herein, a unique synthetic strategy based on polyaniline (PANI) doped 2D cobalt-iron layered double hydroxide (CoFe-LDH/P) nanomaterials are designed, and the formation of pores at low temperature (80 °C) is developed. It is found that the optimized concentration of PANI creates the nanopores on the CoFe-LDH nanosheets among all other polymers. The well-ordered pores of CoFe-LDH/P allow the high accessibility of the redox-active sites and promote effective ion diffusion. The optimized CoFe-LDH/P2 cathode reveals a specific capacitance 1686 (1096 Cg −1 ) and 1200 Fg −1 (720 Cg −1 ) at 1 and 30 Ag −1 respectively, a high rate capability (71.2%), and a long cycle life (98% over 10 000 cycles) for supercapacitor applications. Charge storage analysis suggests that the CoFe-LDH/P2 electrode displays a capacitive-type storage mechanism (69% capacitive at 1 mV s −1 ). Moreover, an asymmetric aqueous supercapacitor (CoFe-LDH/P2//AC) is fabricated, delivering excellent energy density (75.9 Wh kg −1 at 1124 W kg −1 ) with outstanding stability (97.5%) over 10 000 cycles. This work opens a new avenue for designing porous 2D materials at low temperature for aqueous energy storage devices.
