Two-dimensional materials with unique physical and chemical properties have recently attracted widespread attention in the field of solar thermal conversion. However, affected by the Fresnel effect, traditional two-dimensional materials such as MXenes, graphene, transition metal disulfide often have relatively significant light reflection losses at the solid–liquid or gas interface. So how to improve the light absorption of the two-dimensional material performance has become a new challenge in photothermal conversion. Here, we use an improved thermal-injection method to uniformly grow Tricopper(I) Bismuth Sulfide (Cu3BiS3, CBS) on the surface of Ti3C2 nanosheets in a nonaqueous polar solvent environment. A three-dimensional nanoflower-nanosheet structure CBS-Ti3C2 for photothermal conversion has been constructed successfully. Owing to the excellent photothermal performance of Cu3BiS3 in the near-infrared region, the good thermal conductivity of Ti3C2, and the unique porous structure of the composite material, the composite achieves broadband absorption of light (more than 90% in the visible light region, more than 80% in the near-infrared region), which optical model and finite element simulation have theoretically verified. The composite material has obtained higher solar-to-heat conversion performance than similar material systems, and the steady-state temperature can reach 62.3 °C under 1 sun incident light intensity. CBS-Ti3C2 is expected to become a light-absorbing layer material for solar vapor generation devices due to its excellent light-to-heat conversion performance and good material flexibility. It still guarantees a reasonably high steam generation rate (1.32 kg·m–2·h–1) even with a thinner material thickness (0.48 mg·cm–2) and a comprehensive conversion efficiency higher than 90%. Besides, CBS-Ti3C2 also exhibits the characteristics of resisting surface salt accumulation, which is conducive to maintaining the long-lasting photothermal seawater evaporation process. The material’s electronic structure and the charge transfer process of the heterojunction interface have been studied with the first-principles calculation. The high light absorption performance and good thermal conductivity of the composite material are theoretically explained and supported.

Pathogens on wounds and infected tissues or pathogens in drinking water or public facilities have been doing great harm in human life. Because of booming drug resistance and superbacteria, the abuse or excessive use of antibiotics during systemic treatment has caused a global antibiotic crisis. However, it usually takes a long time to develop antibiotics. In recent years, photocatalytic antibacterial agents have no drug resistance and side-effects due to their rapid and efficient bactericidal efficacy. They are becoming one of the most hopeful substitutions to antibiotics for dealing with the bacterial diseases and water pollution caused by certain pathogens. Photocatalysis has unique advantages in the field of antibacterials, and its controllability plays an irreplaceable role. This review focuses on the mechanism of photocatalysis, which involves representative photocatalytic semiconductors (metal oxides, metal sulfides, carbon nitride, heterojunction composite materials) and organics (organic polymers and organic small molecules-aggregation induced emission) as well as their photocatalytic antibacterial mechanism. In this paper, we summarize the photocatalytic antibacterial mechanisms by the numbers and current developing of photocatalytic antimicrobial materials applications. Current difficulties and expectations for the future in these fields are presented to stimulate the developing of material manufacturing technologies and their industrialization to combat bacterial infections. In addition, potential application limitations and future research potential are highlighted.

Copper-based multinary sulfides (CMSs) have been the subject of intense research over the past decade due to the numerous outstanding properties that emerge when they are synthesized on the nanoscale. CMS compounds (e.g., CuInS 2 , Cu 2 SnS 3 , Cu 12 Sb 4 S 13 , and Cu 2 ZnSnS 4 ) are best known for their immense potential in energy-related disciplines. Through nanoscale engineering, new and exciting opportunities have opened up for these materials to be used in a wider range of applications. This review accords particular attention to nanostructured CMS materials with porous morphological features to be used in energy, biomedical, catalytic, and sensing applications owing to their large, tunable, and accessible surface area. Although the construction of porous nanostructures of metals and binary materials has already been well established, tailoring porosity in multinary materials like CMSs remains a big challenge due to their multiple elemental components. Herein, we provide useful discussions on the different modes of pore formation that are fundamental to the construction of CMS nanostructures with tailor-made porosity. These pore-forming strategies are classified into three types: (1) Kirkendall effectinduced hollowing, (2) aggregation-based pore formation, and (3) template-assisted pore engineering. The ability to craft porous features in CMS nanomaterials has proven to be beneficial in advancing their properties and expanding their application domains, and thus, future efforts should be devoted to furthering our understanding of the various pore formation mechanisms as this could lead to the construction of more sophisticated porous CMS architectures with optimal performance for desired applications. We anticipate that the design concepts discussed here can be extended to other emerging classes of multinary materials.
