In this work, we report rapid synthesis procedure of MIL-125 (or, Ti-BDC) Metal Organic Framework (MOF) via microwave route. The synthesized product was characterized using SEM, powder XRD, FT-IR analysis, TGA and UV-Vis diffused reflectance spectroscopy. The aim of this work was to establish a faster synthesis methodology for bulk synthesis of a p...

The present work highlights effective transport and removal of Congo red (CR) from its model solution using sunflower oil/tri-n-octylamine (TOA) system in bulk liquid membrane (BLM) transport. Aqueous solution of Na2CO3 with 1 M solution strength was found to be an effective stripping medium for the anionic dye transport. Maximum extraction and rec...

The work highlights the influence of cation doping on photocatalytic activity of MIL-53(Fe) in artificial light. The effect of intrinsic factors, viz. band-gap energy, electron conductivity and surface area, influencing photocatalysis was studied in detail w.r.t. the degradation of brilliant green dye both in the presence and in the absence of H2O2...

ID: AM-020 Abstract Photocatalytic degradation of crystal violet in aqueous solution using MIL-53(Fe) metal organic framework (MOF) and commercially available TiO2 was investigated in presence of sunlight. The bandgap energy for these materials lies within 2.0 eV for MIL-53 (Fe) and 3.2 eV for TiO2 that falls close to the mid-range and later on the...

This work reports the successful incorporation of Au and Ag nanoparticles within MIL-53(Fe) matrix which showed excellent morphological stability and dispersive capability as confirmed via various techniques. Au@MIL-53(Fe), Ag@MIL-53(Fe) were employed as a nanozyme (specifically mimicking peroxidase-like activity) for colorimetric detection of H2O2...

This work highlights a systematic investigation on doping (S²⁻) on photoactive MIL-53(Fe) and its performance evaluation. Doping (structural/interstitial), leading to tailoring of optical band-gap energies of the parent materials to maximize their performances is well known. However, alteration or tuning of band-gap energy may not essentially alway...

This work proposed and demonstrated Emeraldine (a Polyaniline) linking with NH2 functionalized MIL-125 (Ti) Metal Organic Framework (MOF) to be used as a chemical sensor for detection of Dopamine (DA). The covalent coupling of Emeraldine (E) with NH2-MIL-125(Ti) showed marked improvements in electron conductivity as reflected in various intrinsic p...

In this work, a complex dielectrics transformation of the UV-vis diffused reflectance spectra is proposed to estimate the optical band-gap energies of an array of materials classified as semiconductors, conductors and insulators and the results are compared with the more common Kubelka-Munk (K-M) transformation. The results show a close match betwe...

Variability and lack of control over desired structures made synthesis of Ca-BDC metal organic framework (MOF) with permanent porosity difficult with negligible (orthorhombic) to low/moderate (triclinic) porosity and scarcely investigated. This work reports a microwave route of synthesizing Ca-BDC and subsequent adsorption-desorption (release) stud...
