“…Benefiting from their ultra-thin morphological characteristics and abundant surface defects, a large amount of unsaturated metal sites are exposed, providing abundant adsorption for the reactants [111,112] . Photocatalysis can be defined as the process in which light interacts with a semiconductor, and the generated electrons and holes induce a targeted redox reaction on the surface of the catalysts [49,113,114] . Photocatalysis involves four steps: (1) light absorption; (2) generation of electron-hole pairs;…”

Two-dimensional (2D) materials have garnered much interest due to their exceptional optical, electrical, and mechanical properties. Strain engineering, as a crucial approach to modulate the physicochemical characteristics of 2D materials, has been widely used in various fields, especially for energy storage and conversion. Herein, the recent progress in strain engineering of 2D materials is summarized for energy storage and conversion applications. The fundamental understanding of strain in 2D materials is first described. Then, some synthetic methods for modulating the properties of 2D materials via strain engineering are introduced. Further, the applications of strain engineering of 2D materials in energy storage, photocatalysis, and electrocatalysis are discussed. Finally, the challenges and perspectives on strain engineering of 2D materials are also outlined.

In recent years, carbon capture and utilization (CCU) has been explored as an attractive solution to global warming, which is mainly caused by increasing CO 2 emission levels. Many functional materials have been developed for removing atmospheric CO 2 and converting it to more useful forms of carbon. Traditional metallic photocatalytic species have drawbacks�photocorrosion, low visiblelight absorbance, and environmental damage; therefore, metal-free materials have attracted considerable research attention. In particular, boron nitride (BN) possesses unique B−N bonds, characterized by a large difference in the electronegativity of atoms that facilitates CO 2 reduction, and catalytic CO 2 reduction by boron carbon nitride (BCN) has been demonstrated under visible light; hence, these two materials can be considered potential CO 2 reduction photocatalysts. However, further modification of the materials and their applicability to other CCU applications have not been extensively explored. Therefore, we decided to investigate the modification of BCN monolayers, with the aim of ensuring that the properties of the materials are better suited, first, to the requirements of CO 2 photocatalysis, and second, to those of carbon capture or other optoelectronic applications. In this study, we considered various novel BCN monolayers, based on modification via metal-free substitutional doping and nitrogen vacancy creation, and performed first-principles density functional theory calculations. The effects of the modifications on band gap tuning, charge transfer, and the CO 2 adsorption ability were all studied. Specifically, O N -B 13 C 8 N 11 and Si C -2 × 2-BC 6 N were shown to possess excellent properties for photocatalytic CO 2 reduction, and O C -2 × 2-BC 6 N and N v -4 × 4-BN can be considered for future CO 2 capture materials. These results contribute to existing CCU approaches, suggesting that BCN monolayer modification merits further investigation, and offering insights relevant to other photocatalytic applications.
