Utilizing MOF-Ionic liquid nanocatalyst for the creation of dimethyl carbonate from carbon dioxide

Abstract

Mn iso-reticular coordination polymers of 2,5-dihydroxyterphthalic acid (IL@Mn-MOF-47[I]), 4,4′-dioxido-3,3′-biphenyldicarboxylate (IL@Mn-MOF-47[II]), and 4,4´-(anthracene-9,10-diyl)bis(2-hydroxybenzoic acid) (IL@Mn-MOF-47[III]) can be rapidly obtained under room temperature and aqueous conditions using either ammonium hydroxide as the bases to deprotonate the linker. The combination of IL@Mn-MOF-47[I], IL@Mn-MOF-47[II] or IL@Mn-MOF-47[III] and fibrous phosphosilicate (FPS) in nanospaces presents a potentially unprecedented opportunity for the creation of bifunctional nanocatalysts (IL@Mn-MOF-47[I]/FPS, IL@Mn-MOF-47[II]/FPS, and IL@Mn-MOF-47[III]/FPS). This achievement was made possible through a straightforward approach, resulting in the creation of a large distinctive external surface that was assembled through a 3D hierarchical architecture. Furthermore, the catalyst’s structural heterogeneity was examined using various methods, including FT-IR, TGA, SEM, XPS, and TEM. This remarkable catalyst demonstrated significant efficacy in facilitating the reaction between methanol and carbon dioxide. Further investigations revealed the broad applicability of this catalytic system in various substrates. The primary products obtained from this reaction were compounds with favourable to excellent yields.
