Inorganic–Organic Composite Hydrogels Inspired by the Mother of Pearl Used for Efficient Oil–Water Separation and Catalytic Degradation of Organic Pollutants Jiajun Zuo (20831110) Ruiguo Liu (20717882) Nong Wang (18577001) Biochemistry Space Science Microbiology Biotechnology Environmental Sciences not elsewhere classified Chemical Sciences not elsewhere classified Biological Sciences not elsewhere classified within 65 min severe fouling susceptibility pure water flux new material solution flux recovery rate fe – mo 07 × 10 traditional separation membranes membrane exhibits superhydrophilicity efficient advanced treatment dissolved organic pollutants complex oily wastewater study successfully prepares 5 </ sup organic pollutants oily wastewater advanced treatment successfully fabricated separation efficiency functional membrane underwater superoleophobicity theoretical basis successively constructing single functionality simultaneous removal severely limit pearl used l · hierarchical structure catalytic degradation activate peroxymonosulfate 32 %). Traditional separation membranes suffer from inherent limitations of single functionality, severe fouling susceptibility, and incapability of simultaneous removal of dissolved organic pollutants in oily wastewater, which severely limit their advanced treatment and applications. To address the limitations of traditional separation membranes in terms of antifouling and multifunctionality, this study, inspired by the hierarchical structure of nacre, aims to develop a dual-functional inorganic–organic composite hydrogel membrane that possesses both efficient oil–water separation and simultaneous catalytic degradation capacity for organic pollutants. By successively constructing an Fe–Mo/tannic acid inorganic hydrogel layer and a β-cyclodextrin/polyacrylamide organic hydrogel layer on a microporous stainless steel mesh, a functionalized inorganic–organic composite hydrogel membrane (FMH@SS/PAC) was successfully fabricated. The membrane exhibits superhydrophilicity and underwater superoleophobicity and achieves a separation efficiency of over 99.5% for various oil–water mixtures solely under gravity with a pure water flux of 1.07 × 10⁵ L·m^–2·h^–1. It also exhibits excellent cycling stability and antifouling ability (flux recovery rate of 87.32%). Additionally, it can activate peroxymonosulfate (PMS) and effectively degrade Rhodamine B (RhB) within 65 min. This study successfully prepares a highly performing “separation–degradation” dual-functional membrane. Its unique inorganic–organic composite strategy provides a new material solution and theoretical basis for the efficient advanced treatment and reuse of complex oily wastewater. 2026-09-17T00:00:00Z Dataset Media 10.1021/acs.langmuir.6c04026.s004 https://figshare.com/articles/media/Inorganic_Organic_Composite_Hydrogels_Inspired_by_the_Mother_of_Pearl_Used_for_Efficient_Oil_Water_Separation_and_Catalytic_Degradation_of_Organic_Pollutants/33917093 CC BY-NC 4.0
