The application discloses a kind of fibrous felt that can be all-weather fast recovery high viscosity crude oil, preparation method and its application.The fibrous felt includes the fibrous substrate formed by profiled cross-section fiber, and the binder layer, functional layer and hydrophobic coating sequentially loaded on its surface;Functional layer is used to generate Joule heat when energized and generate photo-thermal effect under light;The water contact angle of fibrous felt is greater than 140°.The application also provides its preparation method and application.The application integrates photo-thermal and Joule heat effect in the same felt, realizes all-weather operation ability;Use C-shaped or Y-shaped profiled cross-section fiber, accelerate the penetration and absorption of high viscosity crude oil;Through the synergistic effect of polypyrrole layer and MXene layer, the resistance is significantly reduced and the oil absorption time is shortened.The fibrous felt of the application has simple preparation process, and is suitable for all-weather oil spill recovery in complex environment such as ocean oil spill.

This invention provides a method for preparing a metal-organic framework adsorbent, belonging to the field of adsorbent technology. The invention includes the following steps: dissolving a metal ion salt and an organic ligand in an organic solvent, controlling the reaction temperature and time, centrifuging, washing, and vacuum drying to obtain the metal-organic framework adsorbent; the organic ligand contains one or two of amino, carbonyl, carboxyl, sulfonic acid, and hydroxyl groups; the adsorbent selectively adsorbs glucagon-like peptide-1 analogs. This invention synthesizes a metal-organic framework adsorbent by combining a metal ion salt with an organic ligand containing groups such as amino, carbonyl, carboxyl, sulfonic acid, and hydroxyl groups. It utilizes the charged portion or specific groups in the organic ligand to form hydrogen bonds, ionic bonds, van der Waals forces, and chelation with glucagon-like peptide-1 analog molecules, achieving highly efficient and selective adsorption of glucagon-like peptide-1 analogs, exhibiting high adsorption capacity, fast adsorption rate, and good adsorption stability.

The invention provides a carbon dioxide trapping material containing charged hydration clusters as well as a preparation method and application thereof, and relates to the technical field of environmental governance, direct air trapping and carbon trapping materials. The carbon dioxide trapping material comprises a porous carbon material and charged hydration clusters loaded on the surface or in pores of the porous carbon material, the charged hydration clusters are OH-(H2O) n, and n is 1-7. The invention provides a new application of the OH-(H2O) n charged cluster for capturing atmospheric CO2 at normal temperature and normal pressure for the first time, and breaks through the dependence of the traditional DAC technology on high-temperature regeneration. At present, no research proposing that the OH-(H2O) n charged cluster is used for CO2 trapping exists. The invention provides a brand new technical path for low-energy-consumption and sustainable direct air trapping.
