Natural Soil Clays from a Phaeozem to Synthesize
a Nanocomposite with Exhausted Coffee Grounds
and Ag- and TiO<sub>2</sub>-Nanoparticles for Water, Air,
or Soil Decontamination
Abstract:A nanocomposite using natural clays from a Phaeozem soil, engineered Ag-nanoparticles (NP), TiO 2-NP, and exhausted coffee grounds was synthesized through a single-step by thermal method, to degrade or filtrate pollutants from soils, water or air. The surface characteristics and the porosity of the composite were studied through nitrogen gas adsorption and application of the Brunauer-Emmett-Teller (BET) equation, and the microporous composites ranged a surface area of 17.36 m 2 g-1. X-ray diffraction showed th… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
