Method for making a Zn MOF of formula Zn.sub.2Ht.sub.2CL, where Ht is 1,2,4-triazolate or a combination of 1,2,4-triazolate and one or more other cycloazocarbyl compound, and CL is oxalate or a combination of oxalate and one or more chelating ligand other than oxalate. More specifically, the Zn MOF is Zn.sub.2Tz.sub.2Ox, where Tz is 1,2,4-triazolate and Ox is oxalate. The method includes reacting 2 molar equivalents of 1,2,4-triazole or the combination with cycloazocarbyl compound with 1 molar equivalent of oxalate or the combination with other chelating ligand and adding 2 molar equivalents of Zn.sup.2+ to form the Zn MOF. The solvent used can be a lower alcohol or a miscible mixture of water and a lower alcohol. One or both reaction steps are conducted at a temperature less than or equal to 120° C. and can be conducted at room temperature and ambient pressure.

An acid gas adsorbent that reversibly adsorbs an acid gas contained in a gas to be processed includes: metal oxide porous material particles; and an acid gas adsorbing agent with which the porous material particles are impregnated. Each of the porous material particles has binary pores including: a mesopore having a pore diameter in a nanometer region of 2 nm or more and 200 nm or less; and a macropore having a pore diameter in a micrometer region of more than 0.2 μm. The macropore is an empty pore, and the mesopore is filled with the acid gas adsorbing agent.

A method for assembling and synthesizing Cu.sub.2O particle-supported porous CuBTC includes the following steps of: 1) dissolving polyvinylpyrrolidone (PVP) in ethanol solution to obtain a PVP-ethanol solution; 2) dissolving copper salt in distilled water, and mixing with trimesic acid, salicylic acid, and the PVP-ethanol solution obtained in step 1) under stirring; and 3) conducting a hydrothermal reaction on the mixed solution obtained in step 2) at 120° C. to obtain Cu.sub.2O particle-supported porous CuBTC. The new method introduces salicylic acid during the synthesis of CuBTC. The salicylic acid, as a ligand precursor, forms a porous CuBTC material through the unsaturated coordination of a ligand under the catalysis of Cu ion. The resulting porous CuBTC supported with ultrafine Cu.sub.2O nanoparticles can adsorb high-energy molecules and exhibit excellent crystallinity, porosity, and stability.

A metal organic framework and a method for preparing the same, and an adsorption device employing the metal organic framework are provided. The metal organic framework includes a 3,5-pyridinedicarboxylic acid and a metal ion, which is an aluminum ion, a chromium ion, or a zirconium ion, wherein the 3,5-pyridinedicarboxylic acid is coordinated to the metal ion.

Material compositions have multifunctionality in abatement of water pollution: They are capable of removing hydrocarbons along with various types of other pollutants, such as metals and metal oxides, and phosphates and other organic material, from water streams. In certain embodiments, the multifunctional compositions are comprised of biochar particles, activated carbon particles, or metal (or metal oxide) nanoparticles bound to a cellulosic or other organic matrix material, which are adhered to styrene-butadiene-styrene granules embedded in an M-Class rubber matrix. Methods of synthesis of the multifunctional compositions and products, including filter cartridges and filters, that use such compositions are also disclosed.

Provided herein are devices, systems, and methods for capturing toxic pollutants, such as polycyclic aromatic hydrocarbons. Certain embodiments of the present disclosure are related to a pollutant-absorbing material that includes an absorbent compound, such as sodium copper chlorophyllin, capable of binding to and capturing a toxic pollutant, and methods of making and using the material for the capture of toxic pollutants. The pollutant-absorbing material can be incorporated into an article worn by a person, such as a shirt or a facemask.

A detoxification method includes the steps of inducing flow of patient blood through an extracorporeal device inlet and outlet in fluid connection to the circulatory system of a patient. Biological agents including lipopolysaccharide (LPS) contained within patient blood can be detoxified by passing patient blood over a biochemical reactor surface having attached or immobilized Saccharomyces boulardii alkaline phosphatase enzyme, with the biochemical reactor being contained within the extracorporeal device.
