Amino-functionalized nanofibers (NH ASep) were prepared from modified sepiolite. Silver nanoparticles (AgNPs) were dispersively assembled on the surface of NH ASep. Ag/NH ASep exhibited excellent catalytic activity for the reduction of nitrophenol. Ag/NH ASep nanofibers remained stable and easy to use for the catalytic reaction.…

Adding sepiolite to bentonite-based drilling mud could control its properties at high temperatures. Sepio- lite-based mud is found to provide good rheological properties under 200 Â C[2]. However, macro-size sepiolite mud is not recommended in the drilling…

Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents and catalysts.[1] The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt, who observed that rapidly heating the material, believed to have been stilbite, produced large amounts of steam from water that had been ...…
