Because of their distinctive characteristics, like great surface area and capability of structure modifications, Metal-organic frameworks (MOFs) were endorsed as outstanding candidates for catalysis purposes. The incorporation of MOF into an organic polymer frameworks is thought to be a promising approach to enhance the catalysts performance, however, a facile and low-cost approach to prepare such catalysts is currently missing. Herein, a direct approach for integration the MOF into nanofibers with improved catalytic organic transformation reactions without film rupture is reported. The electrospun NH2-MIL-101 @polyacrylonitrile (PAN) catalyst nanofibers with varied MOF to PAN mass ratio was fabricated by a facile electrospinning approach and used as integrated catalyst for Friedel-Crafts acylation of anisole, esterification of amyl alc., and Knoveonagel condensation reaction of aldehydes. The fabricated MOF-catalysts nanofibers NH2-MIL-101 @PAN show effective anisole acylation, ester production, and Knoveonagel condensation reaction. The anisole acylation, ester production, and Knoveonagel condensation efficiency boosted to 90%, 79%, and 98% after incorporating NH2-MIL-101 nanocrystals into the elctrospun PAN nanofibers. The great surface area, available active centers in the pore architecture, and unsaturated Cr3+ Lewis acid centers are responsible for this exceptional performance. Because of its adaptability, our approach offers a cutting-edge and intriguing platform for the future tailoring of MOF fabrics with a wide range of practical uses. In the experiment, the researchers used many compounds, for example, 2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4Safety of 2-(Anthracen-9-ylmethylene)malononitrile).
2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4) belongs to nitriles. Nitriles are polar, as indicated by high dipole moments. As liquids, they have high relative permittivities, often in the 30s. Industrially, the main methods for producing nitriles are ammoxidation and hydrocyanation. Both routes are green in the sense that they do not generate stoichiometric amounts of salts.Safety of 2-(Anthracen-9-ylmethylene)malononitrile
