Abstract: A functionalized silica sorbent is described. The sorbent comprises mesoporous silica nanoparticles having a surface functionalized with a conjugated system comprising an azole and a phenyl. The surface may be functionalized by a Cu-catalyzed click reaction. The nanoparticles have an average particle size of 10-80 nm, and may be used to adsorb phenolic contaminants from aqueous solutions.

Abstract: Yttria containing hybrid organic-inorganic sol-gels may be used in coatings for capillary microextraction, optionally hyphenated to online HPLC analysis. The sol-gel reaction mixture can use an yttrium trialkoxyalkoxide, such as yttrium trimethoxyethoxide, and a [bis(hydroxyalkyl)-amino-alkyl]-terminated polydialkyl/arylsiloxane, such as [bis(hydroxyethyl)-amine] (BHEA)-terminated polydimethylsiloxane, that can undergo hydrolysis and polycondensation, to form coating materials. Capillaries coated with such sol-gels can have improved extraction efficiency compared, e.g., to pure yttria-based coatings. The CME-HPLC can analyze water samples containing analytes of varied polarity, with excellent extraction of amides, phenols, alcohols, ketones, aldehydes, and polyaromatic hydrocarbons and detection limits ranging from 0.18 to 7.35 ng/mL (S/N=3). Such capillaries can exhibit solvent stability at pH 0 to 14, RSD % between 0.6 to 6.8% (n=3), at a preparative reproducibility RSD between 4.1 and 9.9%.

Abstract: A method for direct methane (CH4) oxidation (DMTM) to methanol (CH3OH) includes passing an oxygen-containing feed gas stream into a reactor containing a copper-loaded mordenite zeolite (Cu-MOR) catalyst particles such that the oxygen-containing feed gas stream is in contact with the Cu-MOR catalyst particles, at a temperature of 100 to 500° C., to form an oxidized Cu-MOR catalyst. The method further includes displacing oxygen in the reactor by nitrogen purging, and further passing a CH4-containing feed gas stream through the reactor in contact with the oxidized Cu-MOR catalyst at a temperature of 50 to 200° C., thereby converting at least a portion of the CH4 to CH3OH. The method further includes regenerating the Cu-MOR catalyst particles to form a regenerated Cu-MOR catalyst. The CH3OH is adsorbed on surfaces and pores of the regenerated Cu-MOR catalyst.

Abstract: An adsorbent and a method of preparing the adsorbent are described. The adsorbent includes a 2-anthracene ammonium magnetic ionic liquid (MIL), and a [FeCl4]− or a [CoCl3]− ion. The adsorbents, 2-anthracene ammonium tetrachloroferrate (III) ([2AA] FeCl4) and 2-anthracene ammonium trichlorocobaltate (II) ([2AA] CoCl3), are prepared by protonation of 2-aminoanthracene, followed by complexation with FeCl3/CoCl2. The adsorbent of the present disclosure is effective in removing contaminants such as heavy metal ions from an aqueous system in a cost-efficient and selective manner.
