XRD and Spectroscopic Investigations of ZIF—Microchannel Glass Plates Composites

Materials, Journal Year: 2023, Volume and Issue: 16(6), P. 2410 - 2410

Published: March 17, 2023

In this study, new composite materials comprising zeolitic imidazolate framework (ZIF) structures and microchannel glass (MCG) plates were fabricated using the hydrothermal method their morphological spectral properties investigated XRD, SEM, FTIR, Raman spectroscopy. XRD studies of powder samples revealed presence an additional phase for a ZIF-8 sample, whereas ZIF-67 samples, which prepared through two different chemical routes, showed no phases. A detailed analysis FTIR micro-Raman spectra formation stable ZIF inside macropores MCG substrate. The hydrophilic nature substrate its interaction with structure resulted in ZIF-MCG composites. We believe that these may find wide range important applications field sensors, molecular sieving.

In this study, a novel hydroxyapatite (HAp)‐based composite, Co‐Cu/ZIF@HAp, was constructed through in situ growth and simultaneous sonication followed by magnetic string. Herein, the HAp‐based nanocomposite obtained which HAp coated with cobalt–copper bimetallic zeolitic imidazolate framework (ZIF) one‐pot synthesis method. The as‐synthesized composite characterized PXRD, FTIR, FE‐SEM, EDS, HR‐TEM, TGA‐DTG, XPS, BET, UV‐DRS techniques, suggested that well ZIF. prepared utilized as catalyst degradation of organic pollutants. Removal pollutants such dyes has become indispensable due to their higher stability, toxicity, mutagenic nature. Two commonly found dyes, namely, Eosin Yellow (EY) Brilliant Green (BG), were chosen for investigation photocatalytic activity as‐prepared catalyst. process carried out under solar radiation, there no utilization any oxidizing reducing agent. Several parameters amount dose, initial concentration dye solution, effect different pH conditions evaluated better understanding performance Co‐Cu/ZIF@HAp composite. Both EY BG almost degraded up 98.3% 99.5%, respectively, within 50 min nanocomposite. Also, quenching test performed confirmed formation superoxide radicals (O 2 −. ) reactive oxygen species (ROS) photodegradation process. repeatedly used five times ascertain stability reusability
