One-pot synthesis of bimetallic metal–organic frameworks (MOFs) as acid–base bifunctional catalysts for tandem reaction

Abstract

Bimetallic MIL-101(Al/Fe)–NH2 exhibits enhanced acid–base bifunctional catalytic activity due to its synergistic mechanism and hierarchical pore system.

Bimetallic metal–organic frameworks and their derivatives

“…Multicomponent reactions and cascade reactions which require the cooperation of different active sites can be accomplished in bimetallic MOFs. [149][150][151][152] Monge and co-workers demonstrated the control of the catalytic activity and selectivity of bimetallic MOFs in a multicomponent one pot Strecker reaction by modulating specically selected metal ratios (Fig. 11D).…”

Recent Progress on Luminescent Metal-Organic Framework-Involved Hybrid Materials for Rapid Determination of Contaminants in Environment and Food

“…The bimetallic MOFs were synthesized and functionalized by amine to be the acid-base bifunctional catalysts through a fast reflux method and were utilized for tandem reaction. The bimetallic MOFs catalysts exhibit enhanced catalytic activity when compared with the catalyst performance of the monometal based MOFs due to the synergistic effect between two metal ions and the hierarchical pore structure of the bimetallic MOFs [69].…”

Preparation of a novel Fe3O4@SiO2@propyl@DBU magnetic core–shell nanocatalyst for Knoevenagel reaction in aqueous medium

“…Knoevenegal reaction is the condensation reaction of a reactive methylene compounds with aldehydes or ketones under weak base conditions, which resulting in α, βunsaturated carbonyl compounds (1). In recent years, to improve the Knoevenegal reaction, protic ionic liquids (2), mesoporous materials (3), amine-functionalized ionic liquid-based periodic mesoporous organosilica (4), carbamic acid ammonium salt (5), zeolite (6), MOFs (7)(8)(9)(10)(11)(12)(13), melamine-derived graphitic carbon nitride (14), molybdenum carbide (15), amines functionalized C 60 (16), quinine (17), polyoxometalate (POM) cluster organic frameworks (18)(19)(20), Pickering emulsion (21), Fe 3 O 4 @ZIF-8 (22) and nanohybrid material (23) have been reported as catalysts to catalyze this reaction. Although these catalysts have good catalytic effect, most of them suffer from harsh recovery conditions, low yield, long reaction time or poor reuse effect.…”
