Geopolymer Microparticles as Up‐and‐Coming H₂S Sorbers

Abstract

Geopolymers are materials composed of aluminosilicates, which upon activation by the alkaline solution, form repeating units, being classified as inorganic polymers. Geopolymers have gained prominence due to obtaining the raw material that can be natural or residual, the ease of production, and cost-effective. These materials are widely used in civil construction for the replacement of Portland cement and also in the environmental area for the remediation of toxic compounds. However, there is a lack in the literature about the applications of these materials. Thus, this work deals with geopolymers for the sorption of hydrogen sulfide gas.

“…However, the development of nanomaterials faces considerable challenges. Enhancing mechanical [22,36,40,41,60,67,70,, electrical [21,27,[30][31][32]35,42,55,59,120,, and microstructural [19,53,63,68,118, attributes in nanocomposites requires precise nanoscale manipulation. This is coupled with issues like reproducibility, cost, and complexity in preparation, adding to the intricacies of nanomaterial research [231][232][233][234][235][236][237][238][239][240][241][242][243][244][245][246][247][248][249][250].…”

Oil Spill Sorber Based on Extrinsically Magnetizable Porous Geopolymer

“…Moreover, the use of magnetic fillers can also improve the sorption capability of these matrices. Magnetic nanoparticles are often used in application fields such as absorption, separation, sensing, and electromagnetic dissipation [6][7][8][9][10][11]. Ordinarily, geopolymers have been used to recover environments degraded by heavy metals [12].…”
