As one of the essential building blocks for bio-chemicals and bio-fuels, the 5-Hydroxymethylfurfural (HMF) production is still challenging in a green and cheap way. This work developed a bio-derived aqueous-natural deep eutectic solvent (A-NADES) to synthesize HMF using α-Al 2 O 3 or Al(OH) 3 as robust catalysts, obtaining high yields of 67.1% and 63.6% HMF from glucose under mild reaction reactions, respectively. Different kinds of starches and starchy food waste also exhibited high conversion efficiency in the A-NADES system. The mechanistic study indicated that the in-situ formed Al (III) site of α-Al 2 O 3 during the reaction was critical for converting glucose-based carbohydrates. A-NADES could be effectively reused six times with a more convenient direct reuse method without significant activity loss. This study suggested a novel A-NADES reaction media in the synergistic reaction with robust aluminum-based catalysts for HMF synthesis, and proposed a novel process of food waste utilization in green solvents.

Micro–nano structures with hydrophobic properties are promising in self-cleaning, anti-corrosion, and anti-icing performance. Here, we report a solvothermal method to construct micro–nano structures on Al–Li alloy by introduction oleylamine. The results show the concentration of oleylamine has an effect on morphology and hydrophobic property of micro–nano structures formed on Al–Li alloy. The X-ray diffraction results indicates the micro–nano structure is mixture with AlOOH and Al(OH) 3 . When the concentration of oleylamine is about 0.48 mol/L, the length of micro–nano structures is up to microscale, the width of micro–nano structures is about 100–200 nm, and the water contact angle can achieve 152.3°. Graphical A hydrothermal solution was prepared by mixing oleylamine, sodium formate, and DMF. Then, the uniform mixed solution was successfully used to prepare micro–nano structures on the surface of Al–Li alloy by a one-step hydrothermal method. The results show that when the concentration of oleylamine reaches the optimal level (0.48 mol/L), the micro–nano structure is uniform and the voids are filled with air, thus forming a superhydrophobic state.

Marine biofouling, resulting from the adhesion of marine organisms to ship surfaces, has long been a significant issue in the maritime industry. In this paper, we focused on utilizing soft and hydrophilic hydrogels as a potential approach for antifouling (AF) coatings. Acrylic acid (AA) with a polyelectrolyte effect and N-(3-sulfopropyl)-N-(methacryloxyethyl)-N,N-dimethylammonium betaine (SBMA) with an antipolyelectrolyte effect were selected as monomers. By adjusting the monomer ratio, we were able to create hydrogel coatings that exhibited low swelling ratio in both fresh water and seawater. The Al(OH)3 nanoparticle, as a physical cross-linker, provided better mechanical properties (higher tensile strength and larger elongation at break) than the chemical cross-linker through the dynamic coordination bonds and plentiful hydrogen bonds. Additionally, we incorporated trehalose into the hydrogel, enabling the repair of the hydrogel network through covalent-like hydrogen bonding. The zwitterion compound SBMA endowed the hydrogel with excellent AF performance. It was found that the highest SBMA content did not lead to the best antibacterial performance, as bacterial adhesion quantity was also influenced by the charge of the hydrogel. The hydrogel with appropriate SBMA content being close to electrical neutrality exhibits the strongest zwitterionic property of PSBMA chains, resulting in the best antibacterial adhesion performance. Furthermore, the pronounced hydrophilicity of SBMA enhanced the lubrication of the hydrogel surface, thereby reducing the friction resistance when applied to the hull surface during ship navigation.

In this work, a superhydrophobic magnetic photothermal flame-retardant polyurethane sponge (AH/Fe-MOF-P@Fe 3 O 4 @PA@PU) with efficient oil–water separation performance was prepared. After coating the polyurethane sponge with a phytic acid (PA) film, the new honeycomb-like “three-in-one” flame-retardant AH/Fe-MOF-P and magnetic nanoparticle Fe 3 O 4 were firmly bound to the sponge by polydimethylsiloxane (PDMS). AH/Fe-MOF-P@Fe 3 O 4 @PA@PU exhibited excellent superhydrophobicity (with a water contact angle of 155.3°), an oil–water separation efficiency of up to 99%, outstanding recyclability, and environmental stability. Utilizing its magnetic properties, it can be applied to special and complex oil spill treatments. The AH/Fe-MOF-P@Fe 3 O 4 @PA@PU composite exhibited exceptional photothermal properties and demonstrated highly efficient adsorption capabilities for high-viscosity crude oil. Furthermore, the modified sponge possessed remarkable flame-retardant properties, exhibiting the ability to self-extinguish within 2 s following ignition. The superhydrophobic magnetic flame-retardant polyurethane sponge has great potential as an effective oil spill remediation material.
