It is commonly known that silymarin, a phytoconstituent obtained from the Silybum marianum plant, has hepatoprotective and antioxidative properties. However, its low oral bioavailability and poor water solubility negatively impact its therapeutic efficacy. The goal of the present study was to determine the efficiency of the Cordia myxa extract-based synthesized zeolitic imidazole metal–organic framework (CME@ZIF-8 MOF) for increasing silymarin’s bioavailability. A coprecipitation technique was used to synthesize the CME@ZIF-8 and polyethylene glycol-coated silymarin-loaded MOFs (PEG-Sily@CME@ZIF-8) and a complete factorial design was used to optimize them. The crystalline size of CME@ZIF-8 was 14.7 nm and the size of PEG-Sily@CME@ZIF-8 was 17.39 nm. The loading percentage of the silymarin drug in CME@ZIF-8 was 33.5%. The optimized formulations were then characterized by ultraviolet–visible (UV–vis) spectroscopy, X-ray diffraction, Fourier transform IR spectroscopy, surface morphology, gas chromatography–mass spectrometry, and drug release in an in vitro medium. Additionally, a rat model was used to investigate the optimized formulation’s in vivo hepatoprotective effectiveness. The synthesized silymarin-loaded CME@ZIF-8 MOFs were distinct particles with a porous, spongelike shape and a diameter of (size) nm. Furthermore, the designed silymarin-loaded PEG-Sily@CME@ZIF-8 MOF formulation exhibited considerable silymarin release from the synthesized formula in dissolution investigations. The in vivo evaluation studies demonstrated that the prepared PEG-Sily@CME@ZIF-8 MOFs effectively exhibited a hepatoprotective effect in comparison with free silymarin in a CCl4-based induced-hepatotoxicity rat model via ameliorating the normal antioxidant enzyme levels and restoring the cellular abnormalities produced by CCl4 toxication. In combination, biologically produced CME@ZIF-8 may promise to be a viable biologically based nanocarrier that can enhance the loading and release of silymarin medication, which has low solubility in water.

“…According to Tauc's plot, the band gap is 1.35 eV. Compared to the band gap of bulk materials, i.e., 2.6 eV (FeOOH), 2.35 eV (Fe 2 O 3 ), 2.8 eV (Co 3 O 4 ), 3.37 eV (ZnO) and 1.7 eV (CuO), [36][37][38] the obtained nanomaterials from this method display low band gaps, displaying that they are more likely to degrade organic and inorganic pollutants effectively. Hence, the synthesised materials have great potential as photocatalysts.…”

“…Amid various metal oxides, iron-based oxides are viewed as effective materials for both fundamental and practical significance and have attractive properties, such as earth abundance, simplicity to construct, environmentally benign, excellent stability, and well-regulated morphology. , In comparison to the other iron-based oxides, hematite phase iron oxide (Fe 2 O 3 ) is a stable material that is used in various fields, for example, supercapacitors, sensors, batteries, and biological applications. − However, the stability of hematite suffers in the electrochemical reaction. The ultimate aim in this field is to decrease the overpotential of the prepared electrode, which was usually achieved by the tuning of morphological and electronic properties .…”

Fossil fuels are going out of stock as a result of population and industrial growth, and the uptake of fossil fuels has also affected the atmosphere, causing pollution and other defects. Over the past few years, researchers focused on fuels from renewable sources that are unharmful to humans and the Earth’s atmosphere. Constructing lucrative and highly competent electrocatalysts is still a challenging task in the oxygen evolution reaction (OER) activity. In this study, we have synthesized Fe2O3 with N- and S-doped reduced graphene oxide (rGO) via the co-precipitation technique subsequent to the annealing procedure. The formation of rhombohedral phase Fe2O3 spherical nanoparticles on N- and S-doped rGO has been examined. The introduction of N- and S-doped rGO has not only reduced the agglomeration of the particles and particle size but also facilitated the electronic structure. As a result, the Fe2O3/N- and S-doped rGO nanocomposite requires only 250 mV to attain 10 mA/cm2 and the Tafel slope value of 115 mV/dec in an alkaline medium. With the benefit of the presence of N- and S-doped graphene sheets, charge-transfer resistance of Fe2O3/N and S rGO was lower in 24.9 Ω and also exhibited a large electrochemical surface area of 110 cm2. Therefore, our findings suggest that iron oxide decorated in a carbon matrix could efficiently enhance the OER activity to accomplish alkaline water splitting.
