Photocatalytic degradation technology has received much attention from researchers in the last few decades, due to its easy and cost-effective nature. A lot of review articles have been published on dyes via photocatalytic degradation, but most lack a detailed in-depth mechanism dyes. Numerous are available photocatalysis. Here, this article, we mainly focused complete four commonly used such as Malachite Green, Methylene Blue, Congo Red Rhodamine B, which will be highly useful for new that work dyes’ degradation. Initially, various aspects included comprehensively. The main focus was covalent organic framework-based photocatalysts their porous nature unique properties. Various synthesis routes performance frameworks composite highlighted article. In section stimulus mentioned properties, uses, toxicity, through paths into environmentally friendly less-harmful compounds presence photocatalysts. Factors effecting economic cost, challenges future were also This article those search complex dye molecules.

An Imine-Based Two-Dimensional Covalent Organic Framework for Gemcitabine Delivery

Colloids and Interfaces, Год журнала: 2025, Номер 9(1), С. 8 - 8

Опубликована: Янв. 21, 2025

A 2D imine-linked covalent organic framework (COF) with good biocompatibility was synthesized using o-Dianisidine and 1,3,5-Triformylbenzene. The COF characterized by the Fourier transform infrared (FTIR), thermogravimetry analysis (TGA), scanning electron microscopy (SEM), transmission (TEM). subsequently utilized for delivery of gemcitabine (Gem), an FDA-approved drug treatment pancreatic cancer. demonstrated a remarkable loading 30 µg/mg better release at pH 5.0. evaluated in L929 (mouse fibroblast) cell line, while cytotoxicity Gem-loaded (COF-Gem) against MIA-PaCa-2 PANC-1 (pancreatic cancer) lines MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. results indicated that safe concentrations up to 200 µg/mL, COF-Gem led superior as compared native Gem, IC50 values 8.1 ± 1.2 µM cells 6.0 1.3 after 48 h. This study offers new perspective utilizing promising system Gem delivery.

ACS Nano, Год журнала: 2024, Номер unknown

Опубликована: Июль 19, 2024

In order to expand the applicability of materials and improve their performance, combined use different has increasingly been explored. Among these materials, inorganic–organic hybrid often exhibit properties superior those single materials. Covalent organic frameworks (COFs) are famous crystalline porous constructed by building blocks linked covalent bonds. recent years, combination COFs with other shown interesting in diverse fields, composite TiO2 have investigated more more. These two outstanding through bonding, physical mixing, methods excellent performance various including photocatalysis, electrocatalysis, sensors, separation, energy storage conversion. this Review, current preparation applications COF-TiO2 introduced detail, future development possible problems discussed prospected, which is great significance for related research. It believed that will show greater application value as research progresses.

Probing Defects in Covalent Organic Frameworks

ACS Applied Materials & Interfaces, Год журнала: 2024, Номер 16(38), С. 50096 - 50114

Опубликована: Сен. 16, 2024

Defects in covalent organic frameworks (COFs) play a pivotal role determining their properties and performance, significantly influencing interactions with adsorbates, guest molecules, substrates as well affecting charge carrier dynamics light absorption characteristics. The present review focuses on the diverse array of techniques employed for characterizing quantifying defects COFs, addressing critical need field materials science. As will be discussed this review, there are basically two types referring either to missing moieties leaving free binding groups material or structural imperfections resulting lower crystallinity, grain boundary defects, incomplete stacking. summarizes an in-depth analysis state-of-the-art characterization techniques, elucidating specific strengths limitations each defect type. Key examined include powder X-ray diffraction (PXRD), infrared spectroscopy (IR), thermogravimetric (TGA), nuclear magnetic resonance (NMR), photoelectron (XPS), scanning electron microscope (SEM), transmission microscopy (STEM), tunneling (STM), high resolution microcoe (HRTEM), gas adsorption, acid-base titration, advanced methods, computational calculations. We critically assess capability technique provide qualitative quantitative information about COF offering insights into complementary nature potential synergistic use. last section main concepts provides perspectives future development overcome existing challenges.
