A New Mixed-Metal Phosphate as an Efficient Heterogeneous Catalyst for Knoevenagel Condensation Reaction

The escalating demand for the cost-effective synthesis of valuable fine chemicals has fueled search sustainable heterogeneous catalysts. Among these catalytic reactions, Knoevenagel condensation emerged as a very demanding reaction due to its involvement in new C–C bond formation. Porous metal phosphates have attracted significant attention catalysis their unique surface properties. In this study, we report novel porous magnesium aluminum phosphate (MALPO) material through hydrothermal template-free approach. MALPO exhibited promising specific area and hierarchical porosity. Moreover, plate-like morphology can enhance exposure sites located at surfaces, leading enhanced activity. demonstrated excellent performance, yielding series products with up 99% yield. Notably, catalyst displayed remarkable recyclability, retaining structural integrity throughout multiple cycles. findings highlight potential mixed-metal phosphates, exemplified by MALPO, efficient base value-added chemicals, contributing growing chemical industry. Further investigations are warranted explore diverse transformations optimize performance large-scale operations.
