“…Unfortunately the displayed results of the impedance measurements are highly selective and incomplete; details on, e.g., the value of C diff might have helped in understanding the reasons of the remarkable power retention. For sodium ion storage materials, the percentage reached 95% [66], 82.8% [67], or 90.3% [68].…”

Relevant fundamentals of the electrochemical double layer and supercapacitors utilizing the interfacial capacitance as well as superficial redox processes at the electrode/solution interface are briefly reviewed. Experimental methods for the determination of the capacity of electrochemical double layers, of charge storage electrode materials for supercapacitors, and of supercapacitors are discussed and compared. Intrinsic limitations and pitfalls are indicated; popular errors, misconceptions, and mistakes are evaluated. The suitability of available methods is discussed, and practical recommendations are provided.

“…Subsequently, TiO 2 was observed to serve as a hard particle to cut SnS 2 into NPs and also suppress the agglomeration of SnS 2 during cycling. [ 199 ] This not only maintained the internal structure of the nanomaterial, but also formed a shorter diffusion pathway for Na + compared with SnS 2 @C (Figure 8i), resulting in a reversible capacity of 540.3 mA h g −1 after 100 cycles at 0.5 A g −1 .…”

SnSx (x = 1, 2) compounds are composed of earth‐abundant elements and are nontoxic and low‐cost materials that have received increasing attention as energy materials over the past decades, owing to their huge potential in batteries. Generally, SnSx materials have excellent chemical stability and high theoretical capacity and reversibility due to their unique 2D‐layered structure and semiconductor properties. As a promising matrix material for storing different alkali metal ions through alloying/dealloying reactions, SnSx compounds have broad electrochemical prospects in batteries. Herein, the structural properties of SnSx materials and their advantages as electrode materials are discussed. Furthermore, detailed accounts of various synthesis methods and applications of SnSx materials in lithium‐ion batteries, sodium‐ion batteries, and other new rechargeable batteries are emphasized. Ultimately, the challenges and opportunities for future research on SnSx compounds are discussed based on the available academic knowledge, including recent scientific advances.

“…The specific surface area, which depends on the morphology, would be another important factor for the HER, which can provide abundant HER activity sites and MoS 2 QDs deposition sites for enhanced hydrogen production, and a series of unique 2D and 3D nanostructures have been reported, such as nanotubes, nanosheets, and nanowires . Especially the hollow nanosphere, with the inside–outside double specific surface areas for augmenting the activity sites and hollow structure for enhancing the absorption and structure stability, would be regarded as a recommended candidate. For example, Chen et al have prepared the hollow Mo–N/Mo–C nanosphere structure for enhancing the HER; Zhao et al have reported the hollow‐nanosphere mesoporous g‐C 3 N 4 with remarkable visible light photocatalytic HER .…”

The MoS 2 quantum dots (QDs) modified black Ti 3þ -TiO 2 /g-C 3 N 4 hollow nanosphere heterojunction is synthesized via the continuous chemical template deposition and sculpture-reduction processes. The results of structural characterizations imply that the Ti 3þ -TiO 2 /g-C 3 N 4 /MoS 2 QDs hollow nanosphere heterojunction is prepared successfully. The photocatalytic hydrogen evolution reaction (HER) of the B-TiO 2 /g-C 3 N 4 /MoS 2 QDs (%1524.37 μmol g À1 h À1 ) exhibits an enhancement of %33 folds compared with the normal TiO 2 . Furthermore, the process of photocatalysis and the mechanism of photocatalytic HER enhancement are explored, which can be ascribed to the HER activity sites of MoS 2 QDs, Ti 3þ /O v ions in the Ti 3þ -TiO 2 , and hollow nanosphere heterojunction, which are proved by electrochemical measurements.
