Superfast Synthesis of Carbon Xerogels

ACS Omega, 2023
Carbon xerogels (CXs) provide unique opportunities for numerous applications in the areas of adsorption, separation, insulation, catalysis, and electrochemistry, but their use is hampered by time- and energy-intensive synthesis protocols. Synthesis protocols may require several days or more. Here, we report the synthesis of CXs requiring only 5 h using

Low temperature superparamagnetic nanocomposites obtained by Fe(acac)3-SiO2-PVA hybrid xerogel thermolysis [PDF]

Processing and Application of Ceramics, 2016
Fe(acac)3/silica/PVA hybrid xerogel nanocomposite was obtained by one pot acid catalysed sol-gel synthesis using the homogeneous mixture of iron(III) acetylacetonate (Fe(acac)3), tetraethylorthosilicate (TEOS), and polyvinyl alcohol (PVA).

Nanoparticle-releasing xerogel films prepared by a one-step method

Results in Materials, 2023
Aggregation remains a challenge in the development of solid dosage forms of nanoparticles. Herein, we investigated whether xerogel films can allow sustained release of nanoparticles encapsulating curcumin (as a model drug) while preventing their ...

Synthesis of an Alginate-Based Fe3O4–MnO2 Xerogel and Its Application for the Concurrent Elimination of Cr(VI) and Cd(II) from Aqueous Solution

ACS Omega, 2021
In this study, magnetite–manganese oxide (Fe3O4–MnO2) nanoparticles were synthesized and immobilized on alginate, producing a magnetite–manganese oxide xerogel (mMOX). This eco-friendly xerogel was used as an adsorbent of Cr(VI) and Cd(II).

Preparation and characterization of novel bi-functionalized xerogel for removal of methylene blue and lead ions from aqueous solution in batch and fixed-bed modes: RSM optimization, kinetic and equilibrium studies

Journal of Saudi Chemical Society, 2020
A new bi-functionalized xerogel is fabricated and then was identified by 29Si CP MAS NMR, SEM, FTIR, and nitrogen adsorption–desorption approaches. As-prepared xerogel efficiency for simultaneous uptake of methylene blue (MB) and Pb2+ ions from aqueous ...
