Surfactant-induced hierarchically porous MOF-based catalysts prepared under sustainable conditions and their ability to remove bisphenol A from aqueous solutions

Metal-Organic Frameworks (MOFs) are extensively used in different applications, including heterogeneous catalysis given the fact that practically any center can be designed on demand and is accessible for reactants. Just like other microporous catalysts, limited diffusion of reactants products an endemic drawback also MOFs. To face it, use nanocrystalline MOFs a proven alternative, which addition often accompanied by improvements sustainability synthesis procedure (room temperature, water as solvent, etc.). This work goes further adding surfactant-induced mesoporosity to nanocrystallinity these materials. As proof concept, NH2-MIL-53(Al) CTA+ (cetyltrimethylammonium) were selected sustainably-prepared MOF cationic surfactant, respectively. The system formed massive instantaneous precipitation entrapping generates mesopores aggregates. simple washing with ethanol at room temperature leads material containing outstanding intercrystalline mesoporosity. so-obtaining hierarchically-porous able effectively remove bisphenol A (BPA) from aqueous solution (more than 90% 25 ppm BPA just 10 min temperature), duplicating performance its counterpart prepared absence surfactant.
