A recent class of porous materials, viz., metal–organic frameworks (MOFs), finds applications in several areas. In this work, Cu-based MOFs (Cu–benzene-1,3,5-tricarboxylic acid) along with graphene oxide, viz., Cu-MOF/GO, are synthesized and used further for reducing CO 2 electrochemically. The reduction was accomplished in various supporting electrolytes, viz., KHCO 3 /H 2 O, tetrabutylammonium bromide (TBAB)/dimethylformamide (DMF), KBr/CH 3 OH, CH 3 COOK/CH 3 OH, TBAB/CH 3 OH, and tetrabutylammonium perchlorate (TBAP)/CH 3 OH to know their effect on product formation. The electrode fabricated with the synthesized material was used for testing the electroreduction of CO 2 at various polarization potentials. The electrochemical reduction of CO 2 is carried out via the polarization technique within the experimented potential regime vs saturated calomel electrode (SCE). Ion chromatography was employed for the analysis of the produced products in the electrolyte, and the results showed that HCOOH was the main product formed through reduction. The highest concentrations of HCOOH formed for different electrolytes are 0.1404 mM (−0.1 V), 66.57 mM (−0.6 V), 0.2690 mM (−0.5 V), 0.2390 mM (−0.5 V), 0.7784 mM (−0.4 V), and 0.3050 mM (−0.45 V) in various supporting electrolyte systems, viz., KHCO 3 /H 2 O, TBAB/DMF, KBr/CH 3 OH, CH 3 COOK/CH 3 OH, TBAB/CH 3 OH, and TBAP/CH 3 OH, respectively. The developed catalyst accomplished a significant efficiency in the conversion and reduction of CO 2 . A high faradic efficiency of 58% was obtained with 0.1 M TBAB/DMF electrolyte, whereas for Cu-MOF alone, the efficiency was 38%. Thus, the work is carried out using a cost-effective catalyst for the conversion of CO 2 to formic acid than using the commercial electrodes. The synergistic effect of GO sheets at 3 wt % concentration and Cu + OH – interaction leads to the formation of formic acid in various electrolytes.

“…The exhibited peaks at 1522 cm − 1 , 1440 cm − 1 , and 1370 cm − 1 were ascribed to the symmetric and asymmetric stretching vibrations of the carboxyl groups. The observed peaks at 1108 cm − 1 and 970 cm − 1 were related to the C-N and N-CHO stretching vibrations, respectively, which confirmed the coordination of DMF to Co(II) [27][28][29]. The PPy/x%Co-MOF composites exhibited the characteristic peaks of the pure PPy and Co-MOF that confirmed the presence of these compounds in the as-formed nanocomposites.…”

Nowadays, metal-organic frameworks (MOFs) have emerged as promising tools for different biological applications and therefore, efforts are ongoing to develop more biocompatible MOFs-based nanocomposites. We aimed to fabricate some new conductive nanocomposites of polypyrrole and cobalt-MOF with different weight percentages (PPy/x%Co-MOF) using the solution mixing method and characterize them through FT-IR (Fourier-transform infrared), PXRD (powder X-ray diffraction), SEM (scanning electron microscope), and TEM (transmission electron microscope) techniques. The biocompatibility of nanocomposites was assessed by haemolytic, cytotoxic, and quantitative reverse transcription PCR (qRT-PCR) assays. FT-IR and PXRD results revealed that nanocomposites consisted of pure MOFs and PPy. Moreover, SEM results indicated their spherical morphology along with an average diameter of 190 nm. (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay showed a concentration, and percentagedependent cytotoxic effect of the nanocomposites on some cell lines including 3T3 fibroblasts, MCF-7, and J774.A1 macrophages. Haematological toxicity of PPy/x%Co-MOF composites was less than 7% in most concentrations. Furthermore, PPy/x%Co-MOF composites did not show any significant effect on the expression of cyclooxygenase − 2 (COX-2) and inducible nitric oxide synthase (iNOS) genes. In sum, regarding the haemolytic, proinflammatory, and cytotoxic tests, prepared nanocomposite demonstrated the reasonable in vitro biocompatibility which may be considered as a hopeful platform for further investigations including clinical applications.

“…The band at 1380 cm –1 was assigned to the stretching vibration of C–O. 48 The peaks between 1058 and 765 cm –1 were attributed to aromatic benzene ν(CH). 49 The bands appearing at 582 and 441 cm –1 were attributed to the coordinate and covalent bonding of the cobalt ion with O and N (ν(Co < −O) and ν(Co–N)), respectively.…”

The development of selective and fast optical sensitive chemosensors for the detection and recognition of different cations and anions in a domain is still a challenge in biological, industrial, and environmental fields. Herein, we report a novel approach for the detection and determination of fluoride ion (F – ) sensing based on a salen-cobalt metal-organic framework (Co(II)-MOF). By a simple method, the Co(II)-MOF was synthesized and characterized using several tools to elucidate the structure and morphology. The photoluminescence (PL) spectrum of the Co(II)-MOF (100.0 nM/L) was examined versus different ionic species like F – , Br – , Cl – , I – , SO 4 2– , and NO 3 – and some cationic species like Mg 2+ , Ca 2+ , Na + , and K + . In the case of F – ions, the PL intensity of the Co(II)-MOF was scientifically enhanced with a remarkable red shift. With the increase of F – concentration, the Co(II)-MOF PL emission spectrum was also professionally enhanced. The limit of detection (LOD) for the Co(II)-MOF chemosensor was 0.24 μg/L, while the limit of quantification (LOQ) was 0.72 μg/L. Moreover, a comparison of the Co(II)-MOF optical approach with other published reports was studied, and the mechanism of interaction was also investigated. Additionally, the applicability of the current Co(II)-MOF approach in different real water samples, such as tap water, drinking water, Nile River water, and wastewater, was extended. This easy-to-use future sensor provides reliable detection of F – in everyday applications for nonexpert users, especially in remote rural areas.
