“…At the same time, due to the photocatalytic performance of TiO 2 under ultraviolet (UV) irradiation, most TiO 2 SHL−UWSOB composite materials also have good antifouling and self‐cleaning performance. Meng et al [ 162 ] fabricated multifunctional coatings consisting of TiO 2 and waterborne polyurethane onto various substrates. Moreover, the coatings have repeated photocatalysis capability for oil and dyes, while the oil–water separation capacity will not be reduced.…”

The water pollution problem caused by large-scale industrial activity is becoming increasingly serious, which not only poses a major threat to the ecosystem and human health but also seriously impedes the green and sustainable development of modern society. It is urgent to efficiently purify stubborn wastewater containing oils and other pollutants to eliminate their harm to human and environment. Therefore, it is desirable to develop multifunctional materials that can simultaneously remove oil and various pollutants or microorganisms by filtration or absorption methods to meet the practical demand for highly effective purification of wastewater with complex components. This paper summarizes the latest research progress on the "oil

“…Unlike "oil-removing" materials, "water-removing" materials with superhydrophilic/superoleophobic property can selectively separate water from oil/water mixtures. [74][75][76][77] Compared with the "oil-removing" type, "water-removing" materials possess obvious advantages, 14,16,56,73 as follows: (a) the superoleophobicity of "water-removing" materials greatly protects the materials from fouling by oils, thereby fundamentally overcoming the limitation of oil contamination and endowing the oil/water separation materials better performance in terms of service life, recycling of oil and recyclability of materials; (b) "water-removing" materials exhibit more conspicuous application advantages in practical gravity-driven separation processes, given that oil is typically less dense than water; and (c) "waterremoving" materials exhibit unique superiority in oil spills because they can achieve oil enrichment and recovery. Based on the above-mentioned advantages, an increasing number of "water-removing" materials have been designed and manufactured.…”

In the field of interface science, superwettability and photocatalysis are two significant research hot spots. Currently, wettability has been proved to be a decisive factor to enhance photocatalytic activity, such as self-cleaning, degradation efficiency, water purification, antibacterial, gas evaluation, reduction, fixation, H 2 O 2 generation, and so on. In this review, we summarize the recent developments of photocatalysts based on varied bioinspired wettabilities. In the beginning, the amazing wetting behaviors of natural creatures, i.e., superhydrophilic fish scale and clam shell, superhydrophobic lotus leaf and rose petal, patterned wettable desert beetle, slippery pitcher plant, and oleophobic springtail were are and their corresponding wetting models are also exhibited. Subsequently, the catalytic mechanisms of titanium dioxide (TiO 2 ) and graphitic carbon nitride (g-C 3 N 4 ) are discussed. Subsequently, materials based on bioinspired superwetting, including (super)hydrophilicity, superhydrophobicity, patterned superwetting, responsive (super)wetting, Janus (super)wetting, slippery, and superamphiphobicity, are respectively exemplified. Finally, concerns and outlooks related to bioinspired superwettable photocatalysts are proposed. It is believed that bioinspired superwetting in photocatalysis will become an emerging research hot spot in the near future.
