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.

“…In our previous studies, a suite of Mo-based transition metal oxides and sulphides were investigated as candidate materials for Hg 0 removal [27,28]. The presence of Mo species in metal oxides was found to promote Hg 0 removal [27], and the MoS2 nanosheets exhibited outstanding Hg 0 removal performance [16,[29][30][31].…”

In this research, ab initio calculations and experimental approach were adopted to reveal the mechanism of Hg 0 adsorption on MoS2 nanosheets that contain various types of defects. The ab initio calculation showed that, among different structural defects, S vacancies (Vs) in the MoS2 nanosheets exhibited outstanding potential to strongly adsorb Hg 0. The MoS2 material was then prepared in a controlled manner under conditions, such as temperature, concentration of precursors, etc., that were determined by adopting the new method developed in this study. Characterisation confirmed that the MoS2 material is of graphene-like layered structure with abundant structural defects. The integrated dynamic and steady state (IDSS) testing demonstrated that the Vs-rich nanosheets showed excellent Hg 0 adsorption capability. In addition, ab initial calculation on charge density difference, PDOS, and adsorption pathways revealed that the adsorption of Hg 0 on the Vs-rich MoS2 surface is non-activated chemisorption.

TiO 2 catalyst in an internal-illuminated honeycomb photoreactor was prepared for Hg 0 removal from flue gas. The Hg 0 removal efficiency was above 95% under the optimal operation condition. With the increasing TiO 2 coating value, the Hg 0 removal efficiency significantly increased. The catalyst calcined at 400 °C presented optimal Hg 0 removal performance, while higher calcination temperature weakened the Hg 0 photocatalytic removal activity. Similar Hg 0 removal performances were obtained under UV irradiation when the reaction temperature was in the range 25−90 °C, and 1.5 mW/cm 2 of UV light irradiation was competent for Hg 0 photocatalytic removal. With the same quantity utilization of TiO 2 catalyst, the internal-illuminated honeycomb photoreactor presented better Hg 0 removal performance than the fixed-bed reactor. Finally, the procedure of Hg removal from flue gas over TiO 2 catalyst in internal-illuminated honeycomb photoreactor was proposed, and the product in the Hg 0 photocatalytic removal process was analyzed as well.
