Hierarchically structured magnesium based oxides: synthesis strategies and applications in organic pollutant remediation
Hierarchically structured materials have emerged as promising alternatives in the field of adsorption and separation technology owing to their fascinating physicochemical properties such as extraordinarily high surface area, ultrahigh porosity, well-defined morphologies, facile transportation, and easy recovery. Recently, a lot of encouraging research has been conducted on rational design and synthesis strategies of hierarchical MgO and other magnesium-based mixed oxides architectures, and their applications, especially in the field of adsorption and remediation of organic contaminants. To promote and highlight the progress in the development and applications of unique MgO based hierarchical structures, a thorough summary is essential. In this review, we recapitulate advances on synthesis strategies for hierarchically ordered MgO and MgO-based mixed oxides as adsorbents and provide an outline for their applications in toxic organic pollutant remediation from waste-water systems by analyzing selected examples. Finally, we will outline the issues and challenges for developing materials to increase their efficiency for remediation of organic effluents.
