Research on two-dimensional (2D) materials has been explosively increasing in last seventeen years in varying subjects including condensed matter physics, electronic engineering, materials science, and chemistry since the mechanical exfoliation of graphene in 2004. Starting from graphene, 2D materials now have become a big family with numerous members and diverse categories. The unique structural features and physicochemical properties of 2D materials make them one class of the most appealing candidates for a wide range of potential applications.In particular, we have seen some major breakthroughs made in the field of 2D materials in last five years not only in developing novel synthetic methods and exploring new structures/properties but also in identifying innovative applications and pushing forward commercialisation. In this review, we provide a critical summary on the recent progress made in the field of 2D materials with a particular focus on last five years. After a brief background 物理化学学报 Acta Phys. -Chim. Sin. 2021, 37 (12), 2108017 (3 of 151) introduction, we first discuss the major synthetic methods for 2D materials, including the mechanical exfoliation, liquid exfoliation, vapor phase deposition, and wet-chemical synthesis as well as phase engineering of 2D materials belonging to the field of phase engineering of nanomaterials (PEN). We then introduce the superconducting/optical/magnetic properties and chirality of 2D materials along with newly emerging magic angle 2D superlattices. Following that, the promising applications of 2D materials in electronics, optoelectronics, catalysis, energy storage, solar cells, biomedicine, sensors, environments, etc. are described sequentially. Thereafter, we present the theoretic calculations and simulations of 2D materials. Finally, after concluding the current progress, we provide some personal discussions on the existing challenges and future outlooks in this rapidly developing field.

“…Figure summarizes the HER performance of MoSe 2 -based materials reported in the literature. Impressively, the His -MoSe 2 electrocatalyst shows a superior HER performance to those reported MoSe 2 -based materials such as 1T-MoSe 2 , , O-doped MoSe 2 , MoSe 2 on carbon fiber, CV-MoSe 2 , LH and VH MoSe 2 , etc. − The superior HER performance of the His -MoS 2 /PtNPs can be attributed to the following aspects: (1) The histidine acts not only as an exfoliant to exfoliate bulk TMDs into monolayer TMDs sheets but also as a nitrogen source to prepare mixed 2H/1T phase MoSe 2 . (2) The surface potentials of the TMDs can greatly influence the HER performance.…”

Two-dimensional transition-metal dichalcogenides (TMDs) are promising as efficient and earth-abundant electrocatalysts for the hydrogen evolution reaction (HER). However, only the edge and defect sites show HER catalytic properties, while the basal plane, which has nonexistent unsaturated sites, is inactive. Herein, we tackle the key challenge of increasing the number of electrocatalytic sites by using a general and facile method for the effective layer-by-layer exfoliation of TMDs in water by using an amino acid, histidine (His), for the scalable production of single-layer TMDs nanosheets, which cannot be achieved using other common amino acids. Besides serving as an effective exfoliating agent, the N of His can also serve as a doping agent to modulate the phase of single-layer TMDs nanosheets for greatly improving their electrocatalytic performance. The exfoliated single-layer MoSe2 nanosheets were doped with high surface/bulk ratio Pt nanoparticles (PtNPs) to form MoSe2/PtNPs composites. Detailed electrochemical characterization shows that the MoSe2/PtNPs composite (0.45 at % Pt) exhibited an excellent HER performance with an ultralow overpotential of 198 mV (@100 mA cm–2), a Tafel slope of 24 mV/dec, and long-term electrochemical durability.

“…The semicircle curve in the high-frequency area is associated with the charge-transfer resistance (R ct ) in electrode materials. [3,19] And, the slanted linear in the lowfrequency region corresponds to Warburg impedance (R w ), which is related to the diffusion of ions at the electrode/ electrolyte interface. [3b] The corresponding fitting result indicates that the NiO/PNF displays the lowest equivalent series resistance (R s ) of 0.4 Ω and R ct of 10.4 Ω, lower than that for Ni(OH) 2 /PNF (R s , 0.56 Ω, R ct , 35.8 Ω).…”

The combination of excellent mechanical properties and electrochemical performances of Ni-based cathodes is fascinating and challenging for NiÀ Zn batteries. Herein, a novel and eco-friendly strategy of the cycle of Ni 2 + hydrolysis and H + etching process at Ni/solution interface under moderate temperature is demonstrated to synthesize the three-dimen-sional NiO nanosheets array supported on pressed Ni foam electrode (denoted as NiO/PNF). The as-prepared NiO/PNF electrode exhibits outstanding mechanical flexibility and stability with a capacity of 5.08 mAh cm À 3 . The assembled NiO/PNF j j Zn battery presents peak energy and power densities up to 5.2 mW h cm À 3 and 1944.4 mW cm À 3 .
