A Highly Sensitive and Flexible Metal-Organic Framework Polymer-Based HS Gas Sensor.

We report the fabrication of a novel metal-organic framework (MOF)-polymer mixed-matrix flexible membrane for the detection of hydrogen sulfide (HS) gas at room temperature. This high-performance gas sensor is based on MOF-5 microparticles embedded on a conductivity-controlled chitosan (CS) organic membrane. The conductivity of the organic membrane is controlled by blending it with a glycerol ionic liquid (IL) at different concentrations.

Photocatalytic reduction of 4-nitroaniline in aqueous solution using BiOCl/BiOBr/rGO ternary heterojunction under simulated UV-visible light irradiation.

BiOCl/BiOBr/rGO ternary heterojunctions were synthesized and characterized, and their photocatalytic activities were examined. Three different rGO mass ratios were incorporated into BiOClBiOBr; 1% rGO, 3% rGO, and 5% rGO, respectively. The successful incorporation of rGO into the composites was confirmed using powder X-ray diffraction (PXRD).

Photocatalytic Activities of FeNbO/NH-MIL-125(Ti) Composites toward the Cycloaddition of CO to Propylene Oxide.

Photocatalytic utilization of CO in the production of value-added chemicals has presented a recent green alternative for CO fixation. In this regard, three FeNbO/NH-MIL-125(Ti) composites of different mole ratios were synthesized, characterized using Powder X-ray diffraction (PXRD), UV-vis diffuse reflectance spectroscopy (UV-Vis DRS), Brunauer-Emmett-Teller (BET), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDX). PXRD patterns confirm the co-existence of the parent components in the prepared composites.
