In this research, the ultrasound (US) technique was applied as a facile synthesis method for preparing the black TiO2‐g‐C3N4 type II heterojunction, coupled with a Schottky junction MOF (ZIF‐67)‐derived x wt% Co3S4/nitrogen‐doped carbon (NC) (x = 3, 10, and 15) with hollow nanobox (HNB) morphology, as a smart nanoheteroarchitecture (NHA) photocatalyst to enhance visible‐light photocatalytic activity. Additionally, the solvothermal synthesis route was employed to fabricate the MOF (ZIF‐67)‐derived Co3S4/NC cubic hollow nanoboxes (CHNBs) before the pyrolysis process. The black TiO2‐g‐C3N4 wt% Co3S4/NC (TiCN‐15% CoS/NC) NHAs exhibited high photocatalytic activity in degrading methylene blue. The synergetic effect of all components in black TiCN‐x wt% CoS/NC NHAs resulted in efficient electron‐hole pair separation and charge mobility on Co3S4/NC HNB and g‐C3N4 surfaces, which led to a highly effective recombination rate of charge carriers and an excellent improvement in photocatalytic performance.

“…MOFs are coordination polymers synthesized through the assembly of metal ions and organic linkers. Their unique properties containing porosity, high surface area, adjustable pore diameter, multiplex topologies, and thermal stability compared to other nanosized materials make them applicable in various fields. − The metals inside the crystalline structure of the MOF are resistant to impurity and oxidation. Also, the interaction of the organic part of the MOF with other materials makes these structures biocompatible, leading to them being widely utilized in bioapplications in recent years …”

In this work, a simple green synthesis method of the novel metal–organic framework (MOF) nanocomposite PCN-224/Au-NPs (Au-NPs = gold nanoparticles) is described. In this regard, initially, PCN-224 was synthesized. Afterward, in a single-step, one-pot procedure, under visible-light irradiation, Au-NPs were fabricated on PCN-224. The cytotoxicity effect of the synthesized PCN-224/Au-NPs nanocomposite was investigated in human colon cancer cells. Determination of the apoptosis induction was done by the Annexin- V/propidium iodide flow cytometry method. Besides, to ascertain the biocompatibility of the synthesized sample, the cytotoxicity of PCN-224/Au-NPs was evaluated on the human embryonic kidney (HEK)-293 cell line. The substantial anticancer activity with the biocompatibility of the structure, the green facile synthesis, and the MOF surface of the synthesized nanocomposite make it special for utilization in therapeutic applications.

[21][22][23] The micropore confinement effect can improve the selectivity toward furfural. Simultaneously, relative to the boom of interest in the adsorption of furfural from aqueous solutions, research into the adsorption process of ZIF-derived porous carbon materials toward furfural from acid-containing solution, although valuable, remains scarce.…”

BACKGROUND: The separation of furfural from a low-concentration multicomponent and acid-containing aqueous solution is a highly demanding process; traditional distillation requires an excessive amount of energy. Herein, we demonstrated ZIF-8-derived microporous carbon (C) as a promising adsorbent for the separation of furfural using adsorption isotherms, dynamic column adsorption, adsorption kinetics and desorption studies.RESULTS: In the competitive adsorption kinetics experiments with a furfural/acetic acid concentration of 50/20 g L −1 , the acetic acid adsorbed in the micropores of NC ZIF-8 1000C-800A gradually was replaced by furfural, whereas the amount of acetic acid in the mesopores of NC ZIF-8 800C-800A slowly increased. In addition, the micropores of NC ZIF-8 1000C-800A exhibited highly efficient and fast adsorption characteristics toward furfural over a wide furfural/acetic acid concentration range (0-50/0-20 g L −1 ) with the furfural adsorption capacity reaching an adsorption equilibrium within 10 min. The results show that the high Brunauer-Emmett-Teller surface area of NC ZIF-8 1000C-800A is responsible for the high furfural adsorption capacity (1205.3 mg g −1 ) and the confined microporous structure can strengthen the π-π interactions between porous C and furfural, thereby enhancing the selectivity of furfural/acetic acid (61.4) in the furfural/acetic acid (50/20 g L −1 ) dynamic column adsorption system. Meanwhile, the desorption ratio of furfural in the dynamic desorption system reached as high as 98.6%.CONCLUSION: The unique micropore-confinement effect and excellent adsorption behavior make NC ZIF-8 1000C-800A an efficient adsorbent for furfural in the furfural-acetic acid system.
