Abstract: Disclosed are a lithium adsorbent, and a preparation method and an application thereof, which relate to the technical of extraction of lithium. The method of the disclosure includes obtaining a lithium adsorbent intermediate by mixing an oil phase with an aqueous phase; and obtaining the lithium adsorbent by mixing the lithium adsorbent intermediate with an organic auxiliary agent; where the oil phase includes a lithium source, an aluminum source, an oil-phase matrix, and an oil-phase auxiliary agent, and the oil-phase matrix includes a high-molecular polymer and vinylidene fluoride; the mixing an oil phase with an aqueous phase includes performing gradient stirring on a mixture of the oil phase and the aqueous phase. According to the disclosure, the high-stability lithium adsorbent can be prepared by optimizing and screening the high-temperature resistant oil-phase matrix and a specific preparation process. Compared with an existing lithium adsorbent, the lithium adsorbent prepared through the disclosure has less degradation, better mechanical strength, and stronger corrosion resistance in a high-temperature environment, and therefore a way of effectively extracting lithium resources from high-temperature and high-salt brine is provided.

Abstract: A carbon dioxide capture structure having a monolithic three-dimensional shape, the structure being porous with interconnected pores which are accessible from an exterior side of the structure. The structure is made of a building material including a first material and a second material. The first material is a sorbent material (e.g. functionalizable for carbon dioxide adsorption). The second material is a binder material including potassium silicate. The present disclosure also relates to a method of making the carbon dioxide structure and a method for removing carbon dioxide from a gas or fluid mixture.

Abstract: A COF@hydromagnesite composite material and its preparation method and application are disclosed. The preparation method of the composite material includes the following steps. Firstly, diisocyanate organic matters are used as a modifier to carry out chemical reaction with the hydromagnesite powder to obtain modified hydromagnesite powder particles. Secondly, tris(4-aminophenyl)amine and 2,5-dihydroxyterephthalaldehyde are adopted as reaction monomers for reacting to obtain the Covalent Organic Framework (COF) material. And finally, taking modified hydromagnesite powder particle as a core and COF as a shell, the COF@hydromagnesite composite material is prepared. The COF@hydromagnesite composite material synthesized by the method disclosed by the disclosure is simple in preparation process, high in stability and good in selectivity, which can be used for adsorption treatment of lead ions in water.

Abstract: Modified chemical structures of cardanol extracted from cashew nut shell oil, and the use of the same to prepare imidazolium ionic liquids (IILs). The IILs can be used to prepare different types of silica, magnetite and calcium carbonate nanoparticles (NPs) as multifunctional oilfield chemicals for use in various oil spill collection, de-emulsification, viscosity improvement, asphaltene dispersant, and enhanced oil recovery applications.

Abstract: Systems and methods for direct air capture of carbon dioxide or other gases utilize a calcium sorbent in a manner that allows for wide scale, relatively low cost implementation. In particular, a calcium sorbent may be provided as a substantially thin coating on one or more substrates and utilized for direct air capture of carbon dioxide through chemisorption. The carbonated sorbent may be disposed of for sequestration of the carbon dioxide or regenerated with capture of carbon dioxide released from the carbonated sorbent during the regeneration process.
