Abstract

Efficient and recyclable water treatment technologies are crucial for the practical removal of Cr(VI) from wastewater. While metal-organic frameworks are widely used in water treatment due to their stability and multiple active sites, their powdered form presents challenges in reclamation, secondary pollution, and aggregation. This study addresses these issues by successfully loading Ce-based MOF onto a polyvinylidene fluoride (PVDF) film using the phase inversion method, resulting in a highly efficient photocatalyst for Cr(VI) reduction. The Ce-BDC/PVDF composite film offers two distinct advantages over powdered forms: enhanced process efficiency and stability, and minimized catalyst loss and recovery energy requirements. The prepared photocatalyst demonstrated the ability to reduce 95.99 % of chromium in solution within 120 min at pH 2 under visible light irradiation. Comprehensive characterization using XRD, SEM, EDS mapping, FT-IR, PL, and UV–vis analysis confirmed the formation of a composite structure.

期刊介绍： Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
