Korean J. Met. Mater. 2021;59(2):99-112.   Published online 2021 Feb 5
DOI: https://doi.org/10.3365/KJMM.2021.59.2.99
Abstract
In this study, silica aerogel particles were synthesized from emulsion droplets as micro-reactors at room temperature under ambient pressure. An economical precursor, sodium silicate, was used as the starting material for silica, and an emulsification technique was applied to form droplets in continuous phase. By controlling the composition of the... More

Synthesis of Porous Silica Particles for the Adsorption of Organic Dye in Aqueous Medium
Young-Sang Cho, Sol Jeong, Soyoung Nam
Korean J. Met. Mater. 2020;58(5):304-318.   Published online 2020 Apr 20
DOI: https://doi.org/10.3365/KJMM.2020.58.5.304

Abstract
This study investigated the removal of the organic dye like methylene blue using porous particles in a batch adsorption process. Porous silica microparticles were synthesized with macropores or meso-macropores and used as adsorbent particles. The hierarchically porous structures with additional mesopores were found to be more effective adsorbent than simple..... More
