“…64,233 In this case, the surface ability to sustain a gas layer in close proximity to reaction sites is crucial to sustaining an ongoing reaction. 64,233,236 Complementary to this, underwater gas transportation becomes essential in many processes, including underwater micro-reactions, water treatment, and selective aeration. [237][238][239][240][241] Whether gases are meant to be delivered to the reaction place or removed away from it, controlling the bubbles pathway is important for process completion.…”

“…244 Gao et al have utilized surface-enhanced Raman spectroscopy (SERS) to investigate the effect of surface wetting behaviour on the plasmon-driven catalytic-coupling reaction of p-aminothiophenol (PATP) into p,p 0 -dimercaptoazobenzene (DMAB), which require the presence of O 2 as an oxidizing agent for PATP molecules. 236 A hierarchical surface made from silver micro-balls decorated with silver nano-dendrites was employed as a SERS active reaction surface, and surface-modification was carried out to make samples with different wetting behaviours; hydrophilic, hydrophobic and superhydrophobic. 236 It was revealed that for superhydrophobic surfaces, a higher Raman intensity was detected for PATP binding to the catalyst surface, indicating an increase in the reaction dynamics.…”

there have been many important advances in the study of superwettable surfaces, such as superhydrophilic surfaces (water contact angle (WCA) close to 0°) and superhydrophobic surfaces (WCA > 150°). [3] By studying the relationship between the structure and the property of superwetting surfaces in nature, more and more ideas are provided for the research of bioinspired materials. [4] In 2009, researches on wetting were expanded to oil-water-solid phases, sparking a new wave of research in this field. [5] Through the continuous exploring of wetting, researchers summarized the system of superwettability comprehensively and classified the wetting phenomena in detail in 2014. [4a] Among numerous wetting phenomena, there is one that related to gas, called gas wettability. Like a solid substrate wetted by a liquid, researchers find that a thin film of gas will appear on the surface of a hydrophobic/superhydrophobic solid when it is immersed in water, indicating that the substrate is wetted by bubbles underwater. [6] Therefore, the concept of gas wettability has been recognized, including aerophilic, superaerophilic, aerophobic, and superaerophobic. [7] The contact state between solid and liquid, namely, liquidsolid diphase or gas-liquid-solid triphase contact state, is of great significance to the behavior of bubbles on the solid substrate under liquid, which plays an important role in scientific research and industrial applications. [8] By studying the relationship between the macroscopic behavior and the microstructure of some plants and animals in nature, researchers have extensively explained the wettability of bubbles, better understood the behavior of bubbles, and thus facilitated the design of various materials. [9] Tuning gas wettability to an appropriate level by regulating the composition and morphology of the material surface can facilitate the formation of superwetting interface (gas-liquid-solid triphase interface) with unique gas transport properties. This has provided the possibility to improve the efficiency of chemical reactions, especially for those with gaseous reactants or products. [10] Herein, we focus on the creation of suitable gas wettability (aerophilic, superaerophilic, aerophobic, and superaerophobic) to introduce gas-liquid-solid triphase interfaces for enhanced reaction performance in chemical reactions involving gases over the past decade, including gas-consuming reactions and gas-forming reactions, which are Wettability is widely studied in biological systems and attracts tremendous attention in numerous fields. Gas wettability has been increasingly investigated for the past few years because of the presence of gases in many reactions that are essential to environmental protection, health monitoring, energy conversion, and industrial catalysis. In general, traditional liquid-solid diphase systems with poor solubility and tardy diffusion of gases severely hinder the reaction efficiency. Researches show that this problem can be effectively solved by creating a gas-liquid-solid triphase reac...
