Soft-template solvent thermal method synthesis of magnetic mesoporous carbon–silica composite for adsorption of methyl orange from aqueous solution

Abstract

A facile soft-template solvent thermal strategy was developed to prepare mesoporous carbon-silica composite (MMCS) by using furfuryl alcohol(FA) as carbon precursor, Pluronic copolymer P123 as template, hydrated iron nitrate as iron source, and teraethylorthosilicate as silicon source and it was applied for the removal of methyl orange (MO). The as-synthesized MMCS with abound of hydrophilic groups processed a high speci c surface area, large pore volume, and good magnetic response. With the increase amount of FA, the surface area and functional groups increased, promoting the adsorption effect. The adsorption isotherm, kinetic and thermodynamics were all studied in detail. Additional, it was shown that the adsorption process could not be interfered by the co-existence of PO 4 3-, NO 3 -, CO 3 2-, SO 4 2and real water matrix. Thus, the MMCS prepared in this study could be utilized as an alternative adsorbent for the removal of methyl orange from aqueous solution.

“…The topological phase transition method, the sonic solvothermal method, and the air atmosphere sintering method are three important homogeneous nucleation methods. The topological phase transition method and sonic solvothermal method can control the formation of phases, particle size, and shape, resulting in products with good dispersibility . The topological phase transition process is typically conducted in a closed system.…”
