Agrowaste-carbon and carbon-based nanocomposites for endocrine disruptive cationic dyes removal: A critical review.

Dyes are considered to be pollutants that pose a considerable worldwide health risk, as they have been discovered as agents that affect the endocrine system. Adsorption is the most commonly used method for removing different substances since it is sustainable, flexible, affordable, and easy to use. Researchers have investigated the usage of agro-waste-based adsorbents that are ecologically friendly for the process of adsorption.

S-Scheme ZIF-67/CuFe-LDH Heterojunction for High-Performance Photocatalytic H Evolution and CO to MeOH Production.

The S-scheme heterojunction photocatalyst holds potential for better photocatalysis owing to its capacity to broaden the light absorption range, ease electron-hole separation, extend the charge carrier lifespan, and maximize the redox ability. In this study, we integrate zeolitic imidazolate frameworks (ZIFs-67) with the CuFe-LDH composite, offering a straightforward approach towards creating a novel hybrid nanostructure, enabling remarkable performance in both photocatalytic hydrogen (H) evolution and carbon dioxide (CO) to methanol (MeOH) conversion. The ZIF-67/CuFe-LDH photocatalyst exhibits an enhanced photocatalytic hydrogen evolution rate of 7.

Anisotropic phenanthroline-based ruthenium polymers grafted on a titanium metal-organic framework for efficient photocatalytic hydrogen evolution.

Conjugated polymers and titanium-based metal-organic framework (Ti-MOF) photocatalysts have demonstrated promising features for visible-light-driven hydrogen production. We report herein a strategy of anisotropic phenanthroline-based ruthenium polymers (PPDARs) over Ti-MOF, a tunable platform for efficient visible-light-driven photocatalytic hydrogen evolution reaction (HER). Several analytical methods including X-ray absorption spectroscopy (XAS) revealed the judicious integration of the surface-active polymer over the Ti-MOF reinforcing the catalytic activity over the broad chemical space.

Technoeconomic Investigation of Amine-Grafted Zeolites and Their Kinetics for CO Capture.

Solid adsorbents with precise surface structural chemistry and porosity are of immense interest to decode the structure-property relationships and maintain an energy-intensive path while achieving high activity and durability. In this work, we reported a series of amine-modified zeolites and their CO capture efficiencies. The amine impregnated molecular zeolite compounds were characterized and systematically investigated for CO adsorption capacity through thermogravimetric analysis for the occurrence of atmospheric pure CO gas at 75 °C with diethylenetriamine (DETA), ethylenediamine (EDA), monoethanolamine (MEA), and triethanolamine (TEA)-loaded zeolite 13X, 4A, and 5A adsorbents.

Noble metal-free integrated UiO-66-PANI-CoO catalyst for visible-light-induced H production.

The discriminate etching chemistry (crystal engineering) of metal-organic frameworks (MOFs) offers promising opportunities for tailoring electron-hole separation, and charge-carrier utilization plays a central role in photocatalysis. Herein, the noble metal-free examples of polyaniline (PANI)-sensitized cobalt oxide functionalized perfect crystal UiO-66 and defective crystal UiO-66D photocatalysts were synthesized and evaluated for photocatalytic hydrogen generation from water under visible light irradiation. A viable route for the simple yet effective modification of UiO-66 by implanting PANI and cobalt oxide was demonstrated for the development of a series of UiO-66-based catalysts.
