“…It has been extensively researched for its photoconductive and photochemical properties, particularly in relation to its potential applications in photocatalysis under visible light irradiation. Furthermore, due to its unique characteristics of a high affinity for organic dyes or antibiotics and a large surface to volume ratio, CuO is also employed as an effective absorbent for removing organic dyes or antibiotics over a wide pH range [10]. However, There is a wide range of methods used to synthesize metal nanoparticles (NPs) [11], from physical to chemical means, which can be resource-intensive and require expensive equipment.…”

Copper oxide nanoparticles (CuO NPs) and CuO NPs decorated with hematite (Fe2O3) nanocomposites (CuO@Fe2O3 NC) were biosynthesized by a green method using Portulaca oleracea leaves extract. The NC were characterized using various techniques, including X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and UV-Vis spectroscopy. The results showed that the synthesized CuO and CuO@Fe2O3 NC were crystalline with a monoclinic crystal structure and contained functional groups responsible for catalytic activity. The size of the nanocomposites ranged from 39.5 to 45.9 nm, and they exhibited a variety of agglomerated or aggregated shapes. The CuO@Fe2O3 NC showed improved photocatalytic activity for the degradation of antibiotics in water and wastewater and promising antiviral activity against SARS-CoV-2, indicating its potential for use in disinfection applications. The study investigated the impact of irradiation time on the photocatalytic degradation of Amoxicillin and found that increasing the irradiation time led to a higher degradation rate. The band gap energy (Eg) for pure CuO NPs was around 2.4 eV and dropped to 1.6 eV with CuO@Fe2O3 NC. In summary, the CuO@Fe2O3 NC has the potential to be an efficient photocatalyst and promising antiviral agent for environmental remediation. The CuO@Fe2O3 nanocomposites have been found to possess a high degree of efficacy in inactivating SARS-CoV-2 infectivity. The results of the study indicate that the nanocomposites exhibit potent anti-viral properties and hold significant potential for use in mitigating the spread of the virus.

“…[20][21][22][23] Nevertheless, due to the negative impacts of chemical methods on the environment, and to satisfy the increasing needs of eco-friendly NPs, it is an energetic need to change chemical preparation methodology with clean, nontoxic, and green chemistry approaches. [24][25][26][27][28][29][30][31][32] Additionally, it turns into heterogeneous catalyst that has importance in transformation. [33][34][35][36][37][38][39][40][41][42][43] Catalyst is easily separable and reusable, decreasing the expense.…”

In the present work, Ficus benghalensis leaf extract was used for the synthesis of ZrO2 nanoparticles. Further, ZrO2@Ag‐S‐CH2‐COOH was synthesized using biosynthesized ZrO2, and its catalytic potential was examined in the synthesis of pyrazoline from reaction of chalcone and hydrazine hydrate at room temperature. The structural conformation of ZrO2@Ag‐S‐CH2‐COOH has been done using FT‐IR, SEM, EDX, XRD, TGA‐TDA, XPS, and DLS techniques, high turnover number (TON), and high turnover frequency. The ZrO2@Ag‐S‐CH2‐COOH demonstrated outstanding catalytic activity for the synthesis of pyrazolines. The structures of the pyrazoline derivatives were confirmed by FT‐IR, 1H and 13C NMR, and mass spectrometry techniques. Synthesized pyrazoline were tested for anticancer activity against human lung cancer cell line A549 study and confirmed by molecular docking investigations.

This study synthesized 1,6‐naphthyridine as a novel class of fused heterocyclic compounds with high efficiency using a multicomponent reaction. The reaction involved benzaldehyde or its derivatives, 2 mol of malononitrile, and 4‐aminocumarin in an aqueous solution at room temperature in the presence of SiO2/Fe3O4@MWCNTs as a recyclable catalyst. This study examines the antioxidant properties of 1,6‐naphthyridine in addition to the other research undertaken in this work. The production process of 1,6‐naphthyridine demonstrated several advantageous features, including rapid reactions, high yields of the final product, and straightforward separation of the catalyst and product from the reaction mixture.
