“…The more negative conduction band (CB) potential (−0.57 V vs. Ag/AgCl) than O 2 /O 2 ˙ − (−0.48 V vs. Ag/AgCl) predicts the availability of oxygen conversion (Fig. 2e and f), 31 which was further demonstrated in reactive oxygen species (ROS) monitoring experiments (Fig. S5†).…”

“…2D COFs are considered to be brilliant materials for various photocatalytic applications. [133,134] For instance, the electronic and photocatalytic properties of porphyrinic 2D COFs may be tuned by incorporating different transition metals into the porphyrin rings, and these COFs showed adjustable photocatalytic HER performance. [130] Chen et al synthesized highly crystalline heptazinebased 2D COFs.…”

Photocatalysis can be understood as the acceleration of chemical reactions by incident light, especially when the catalyst is photoactive. These reactions are unachievable or very difficult without photoactivation. Photocatalysis could find applications in a wide range of fields such as renewable energy (water splitting, CO 2 reduction, solar fuel production) and environmental (water treatment by removing pharmaceutic and pesticides contaminant, for instance, and improving air quality by reducing volatile organic compounds [VOCs]). [1] The advance in the photocatalysis field is driven by developing novel, innovative materials that mainly allow light absorption and efficient charge separation. [2] The most developed photocatalysts are inorganic semiconductors such as metal oxides (such as ZnO, TiO 2 , WO 3 , SnO 2 , and CuO) [3,4] and chalcogenides (ZnS, CuS, CdS, Sb 2 S 3 , Cu 2 SnS 3 , and Cu 2 SnSe 3 ). [5,6] In order to enhance the performance of these semiconductor catalysts, different strategies were investigated to reduce the recombination of photogenerated electron-hole pairs and to extend the absorption edge of these catalysts to the visible region of sunlight: 1) tuning of the morphologies, 2) doping to tune the bandgap, 3) junction between several semiconductor materials, [7,8] and 4) combining with metallic and plasmonic nanomaterials (Cu, Pt, Au, Pd). [9,10] An alternative approach to increase the efficiency of these photocatalysts is the design of organic-inorganic hybrid materials. Two classes of hybrid materials were largely investigated: 1) small molecules such as dyes and molecular catalysts known for their sensitizing and photocatalytic properties, and 2) organic macromolecules or polymers are known for tuning the properties of the semiconductor. These polymers also act as a protective layer, tuning the composites' hydrophobicity/hydrophilicity or lipophilicity. Moreover, they could also provide additional photocatalytic, electron transferring, and conductive properties.Different types of polymers were investigated in the literature, such as polydopamine (PDA), polyaniline (PANI), polythiophene, poly(3-hexilthiophene) (P3HT), polyphenylenevinylenes (PPVs), poly(3,4-ethelenedioxythiophene) (PEDOT), chitosan (CS), poly(pyrrole) (PPy), polyvinyl alcohol (PVA), covalent organic polymer (COP), and covalent organic frameworks (COFs). [11] Two of the most well-established aforementioned conductive polymers are CS and PANI. Despite more than a century of ongoing research, these polymers continue to have a large and highimpact on the literature, as shown by the constantly growing research works published each year. This ever-increasing attention is primarily attributed to the extensive application of both

“…The difference is that the framework of the COF is formed by covalent bonds between light elements (C, N, O, H, B, Si, etc.). Currently, COFs are mainly divided into three types: boron-containing [ 59 ], imine [ 60 ], and triazine [ 61 ]. And they have applications in seawater desalination [ 62 ], oil–water separation [ 63 ], microcapsules [ 64 ], and other fields.…”

The problems of environmental pollution are increasingly severe. Among them, industrial wastewater is one of the primary sources of pollution, so it is essential to deal with wastewater, especially oil and water mixtures. At present, biomimetic materials with special wettability have been proven to be effective in oil-water separation. Compared with three-dimensional (3D) materials, two-dimensional (2D) materials show unique advantages in the preparation of special wettable materials due to their high specific surface area, high porosity, controlled structure, and rich functional group rich on the surface. In this review, we first introduce oil–water mixtures and the common oil–water separation mechanism. Then, the research progress of 2D materials in oil–water separation is presented, including but not limited to their structure, types, preparation principles, and methods. In addition, it is still impossible to prepare 2D materials with large sizes because they are powder-like, which greatly limits the application in oil–water separation. Therefore, we provide here a review of several ways to transform 2D materials into 3D materials. In the end, the challenges encountered by 2D materials in separating oil–water are also clarified to promote future applications.
