超疏水ZnO-rGO/CMF复合材料的构建及其高效吸油-分离性能
Construction of a superhydrophobic ZnO-rGO/CMF composite and its high-efficiency oil adsorption-separation performance
摘要
Abstract
Oily wastewater discharge severely en-dangers the environment and hinders energy conserva-tion efforts,necessitating the development of high-per-formance oil-water separation materials.We report the formation of a superhydrophobic and superoleophilic composite by integrating ZnO with reduced graphene oxide(rGO)on a carbonized melamine foam(CMF)us-ing pristine melamine foam(MF)as the starting sub-strate.The fabrication involved two key steps:hydro-thermal treatment and high-temperature pyrolysis.Char-acterization showed that the resultant ZnO-rGO/CMF composite had a water contact angle of 151.5°,indicat-ing excellent superhydrophobicity.Both static adsorp-tion and continuous dynamic separation tests verified the composite's superior oil-water separation performance.It had remark-able adsorption capacities for various oils and organic solvents,with a maximum adsorption capacity of 120.2 g/g for soybean oil,surpassing the values for most previously reported MF-derived carbon-based adsorbents.After 20 consecutive separation cycles,the composite maintained a stable adsorption performance,demonstrating good recyclability.It also had an excellent compression resistance and good flame retardancy.It retained 70%of its original adsorption capacity for gasoline after five combustion cycles,confirming its reusability under high-temperature conditions.Hydrophobic carbon-based porous sponges were developed,providing valuable insights for the design and development of advanced carbon-based superhydrophobic ma-terials for environmental remediation,particularly in oily wastewater treatment.关键词
