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.

“…Graphene aerogel (GA) is a 3D architecture constructed from plenty of graphene sheets. The high specific surface area and interconnected structure of GA not only guarantee the effective absorption of metal ions but also favor the fast transfer of Na ions and electrons. − Herein, we report an efficient synthetic strategy for fabricating 3D N,P-co-doped graphene (NPG) confined iron phosphide nanodots via phosphidation of NH 2 -rich rGO-supported Fe 2 O 3 . There are two advantages in this unique architecture.…”

Transition metal phosphides have recently gained much interest as anodes for sodium-ion batteries (SIBs). However, their intrinsic volume change during Na ion uptake/release leads to poor cycling stability and limited rate performance. To solve this problem, a unique hybrid architecture of iron phosphide nanodots bound on 3D phosphorus-doped graphitic nitrogen-rich graphene (FeP/NPG) is obtained from the phosphidation of NH2-rich reduced graphene oxide (rGO) decorated Fe2O3. Monodispersed FeP nanodots integrating with 3D NPG networks and high content of graphitic N not only induce fast Na ion/electron transfer kinetic and excellent structural stability during long-term cycling, but also they enhance the capacitive contribution. These features of FeP/NPG result in high-performance sodium storage. A high reversible capacity of 613 mAh g–1 is achieved at 50 mA g–1. Also, an excellent rate capability of 422 and 349 mAh g–1 is observed at 1 and 3 A g–1, respectively. More importantly, an ultrastable capacity of 378 mAh g–1 at 1 A g–1 can be obtained upon long-term cycling. It shall be possible to extend this strategy for fabricating other transition metal phosphide-based anodes for advanced SIBs.
