“…Special optical and electrical properties of 2D materials are expected to provide new approaches to overcome these challenges in the future. Considering that most of current photocatalysts with low solar efficiency were excited by ultraviolet light 1169,1170 , rational design of 2D materials with unique optical properties and wide absorption (up to visible or near-infrared light) is prime important to achieve remarkable nitrogen fixation performance. In addition, inspired by thermal catalytic ammonia synthesis, the enriching electron density of surface defects is a key to promote nitrogen activation [1171][1172][1173][1174] .…”

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.

Summary The photocatalytic hydrogen evolution of MnxCd1‐xS in pure water has been achieved through suitable modification methods and efficient co‐catalysts. This article presents the photocatalytic performance and reaction mechanism of a Ni2P‐modified P‐doped MnxCd1‐xS photocatalyst (PNIMCS). It possesses admirable photocatalytic H2 evolution ability both in pure water and trapping agent solutions. The co‐catalysts Ni2P and P doping make a significant contribution in facilitating the PNIMCS photocatalytic pure water splitting to hydrogen reaction. They make the ECB of PNIMCS more negative, lower the overpotential of the hydrogen evolution reaction, and also promote the separation and transfer of photogenerated h+ and e−, thus improving the hydrogen evolution performance of PNIMCS.

Developing a simple and effective strategy to modulate the energy band bending of heterojunction photoelectrodes is pivotal in terms of photoelectrochemical (PEC) water splitting. Herein, it is demonstrated that the introduction of the interfacial InOSn chemical bonds at the ZnIn2S4/SnS2 interface regulates the band bending of ZnIn2S4/SnS2 heterojunction photoanodes, reverses the charge transport direction, and reduces the oxygen evolution reaction (OER) overpotential. Detailed analysis indicates that the interfacial InOSn bond makes band adaptation to promote carrier separation and transfer through ultraviolet photoelectron spectrometry, hydroxyl radical production tests, and surface photovoltage measurements. Due to the special nanosheet morphology with exposed edges of the heterojunction interface, the InOSn bonds are partially exposed, which can reduce the OER overpotential and boost the surface injection efficiency according to the PEC impedance spectroscopy and density functional theory calculations. The synergistic modulation of InOSn bond yields a photocurrent of 4.57 mA cm−2 at 1.23 V (vs reversible hydrogen electrode, AM 1.5 G) and a low onset potential of −0.14 VRHE. This work provides a new solution for energy band regulation to improve the performance of heterojunction photoelectrodes for PEC water splitting.
