Zinc MOF and Melamine Sponge Composite: A Cutting-Edge Solution for Dose-Dependent Dye Degradation and Ultra-Sensitive Chemical Sensing of Nitro Derivatives and Sucrose

Abstract

This study investigates the innovative applications of the [Zn₉(Cei)₆(Bimb)_*9]_n(Zn-MOF) metal-organic framework and its composite with melamine sponge (Zn-MOF@MS) in the domains of photocatalytic degradation and fluorescence sensing. The Zn-MOF@MS composite demonstrates exceptional performance in the photocatalytic degradation of Rose Bengal (RB) dye, achieving a high degradation rate under optimized conditions (pH 5, 10 mg/L RB concentration, 6 mg photocatalyst dosage, and 120-minute reaction time). Additionally, Zn-MOF exhibits notable fluorescence sensing capabilities, enabling the detection of 2-nitrotoluene (2NT) and sucrose at low concentrations, with detection limits of 0.298 ppm and 1.129 ppm, respectively. These results highlight the novel integration of Zn-MOF with a melamine sponge matrix, showcasing significant advancements in both environmental remediation and analytical chemistry. The study underscores the potential of Zn-MOF@MS as a versatile material with substantial implications for improving dye degradation processes and enhancing chemical sensing precision. This work advances the field by demonstrating the dual functionality of Zn-MOF materials and providing a robust platform for future research and technological development in environmental and analytical applications.
