“…Previously, Rabbani et al 80 reported efficient removal of MB using catalysts of Ag–TiO 2 and Zn‐TCPP/Ag–TiO 2 under UV and visible light irradiation. They found that both synthetic catalysts have higher catalytic activity under UV light than the visible light and removal efficiency of MB reaches the maximum value of 100% for both catalysts 81–85 . Table shows the maximum removal of adsorption and photodegradation of MB by some catalyst 86–90 …”

A new copper (II) coordination complex formulated as [Cu (dipic)(phen)(2‐MePy)]. 2H2O (1) where phen = 1, 10‐phenanthroline, dipic2− = pyridine‐2,6‐dicarboxylato and 2‐MePy = 2‐methyl pyrrole was synthesized through a simple and environment‐friendly reaction under ultrasound irradiation. Also, complex 1 was synthesized by hydrothermal process at 120 °C for 3 days. The corresponding structure of complex 1 was characterized by elemental analysis, atomic absorption spectroscopy (AAS), inductively coupled plasma (ICP), conductivity measurement, Fourier‐transform infrared spectroscopy (FT‐IR), Raman spectroscopy, ultraviolet–visible spectroscopy (UV–Vis), thermal gravimetric analysis (TGA), differential thermal analysis (DTA), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM) and fluorescence. The crystal structure of the hydrothermally synthesized complex was characterized by single crystal X‐ray diffraction (SC‐XRD(, which revealed a triclinic structure. In the remainder of this study, the Cu2O nanoparticles have been prepared via thermal decomposition of hydrothermal and ultrasound complexes and characterized by ICP, FT‐IR, powder X‐ray diffraction (XRD), SEM and N2 adsorption/desorption. Adsorption and visible‐light‐driven photocatalytic capabilities of two synthetic Cu2O were investigated in the removal of MB from water. The result showed that the synthesized catalysts have good catalytic activity and the photocatalytic degradation is more effective in dye removal of MB compared with the adsorption.

“…Choosing a suitable solvent is a very important step in order to design a green and environment-friendly, safe and low-cost reaction procedure. The principle of green chemistry expresses the goal to minimize the environmental impact resulting from the utilization of toxic and hazardous solvents in the chemical production (32)(33)(34)(35). In this work, all the solvents used in optimization are safe and environmentally benign.…”

A novel, green and cost-effective heterogeneous nanocatalyst was synthesized by supporting copper (I) oxide nanoparticles on magnetic agar (Cu 2 O/Agar@Fe 3 O 4). Then, it was characterized with multiple techniques, such as scanning electron microscopy and transmission electron microscopy images, energy-dispersive X-ray analysis, Fourier-transform infrared (FT-IR) spectroscopy, thermogravimetric (TG) analysis, X-ray diffraction pattern, vibrating sample magnetometer curve, and inductively coupled plasma analysis. The catalytic activity of the newly designed catalyst was investigated in a one-pot three-component reaction of alkyl halides, sodium azide, and alkynes to obtain 1,4-disubstituted 1,2,3-triazoles in high yields in waterethanol media. The present catalyst was simply separated from the reaction media by an external magnet and reused at least five subsequent runs without significant activity loss.

“…Among these nanoparticles, silver nanoparticles (Ag NPs) have received great consideration due to their high conductivity, stability, good catalytic activity, and antibacterial and antiviral properties. [6][7][8][9][10][11] The agglomeration of nanoparticles during the catalytic reaction is one of their disadvantages. [12][13][14][15][16] Separation of nanoparticles from the reaction medium using simple methods such as filtration and centrifugation is difficult.…”

The magnetically recyclable graphene oxide‐Fe3O4/polyallylamine (PAA)/Ag nanocatalyst was prepared via a green route using Eucalyptus comadulensis leaves extract as both reducing and stabilizing agent. The catalytic activity of this nanocatalyst was investigated for the reduction reaction of methylene blue and methyl orange in the presence of NaBH4 in aqueous medium at room temperature. The prepared nanocatalyst was characterized by different methods such as Fourier transformed infrared spectroscopy, X‐ray diffraction, scanning electron microscopy–energy dispersive X–ray spectroscopy, thermogravimetric analysis, vibrating sample magnetometer, transmission electron microscopy, and UV–visible spectroscopy. The results show that graphene oxide/PAA/Ag nanocatalyst has good activity and recyclability, and can be reused several times without major loss of activity in the reduction process. The apparent rate constants of the methyl orange (MO) and methylene blue (MB) were calculated to be 0.077 s−1 (3 mg of catalyst) and 0.15 s−1 (2 mg of catalyst), respectively.
