“…Hence, the optimum parameters for the degradation of crystal violet with LCu are: 4.5 mg of catalyst, and 2.25 ml of H2O2 (3 %) in a relatively short reaction time. The results obtained from optimization studies reveal that our copper complex indeed can successfully catalyze the degradation of CV and MB two dyes of different structures and different classes, our compound is as effective as other recently published Schiff base catalysts [35,41]. As a perspective, we plan to replace the UV lamp with sunlight if the gap energy of the catalyst is appropriate [42].…”

The titled mononuclear complex [Cu (L)] with the formally tetradentate schiff base ligand, [N,N’-bis (2-hydroxy-3-methoxybenzylidene)-1,3-diaminopropan-2-ol] has been synthesized and characterized using IR spectroscopy and elemental analysis. Crystal structure has been determined by XRD which reveals the pseudo octahedral complex geometry and the use of hydroxo bridges between two neighbor units to form a 1D coordination polymer. The use of this complex as a catalyst for the degradation of two textile dyes, in the presence of the appropriate amount of H2O2 and a UV light source has given very good results with yields exceeding 98% after 50 minutes.

“… 48 Peaks observed at 1088.8–1091.4 and 802.7–805.7 cm −1 are attributed to asymmetric stretching and bending of Si–O–Si bonds within the MCM-41 framework. 49 The band at 464.4–467.6 cm −1 can be attributed to the vibration of Si–O bonds, indicating the mesoporous silica nature. 48 Moreover, after Li doping onto the MCM-41 framework, a little bump peak appeared at 1383.6 cm −1 appeared, which was attributed to the N–O group of the LiNO 3 precursor due to the presence of the metal oxide within the catalyst.…”

“…Natural enzymes are a class of biocatalysts that can efficiently and specifically catalyze biological reactions under suitable conditions and are capable of maintaining the metabolism of organisms. [ 1 ] Their remarkable catalytic performances offer a wide variety of applications for peroxidases in pharmaceuticals, [ 2 ] environmental treatments, [ 3 ] food industries, [ 4 ] biomimetics, [ 5 ] and biomedical applications. [ 6–8 ] Nevertheless, most natural peroxidases are proteins that are structurally unstable and susceptible to external environments.…”

A Co(II)‐organic framework (Co‐MOF), [Co3(3,5‐bimpy)2(5‐cpia)2(H2O)2], was constructed via the hydrothermal reaction of 3,5‐bis(1‐imidazoly)pyridine (3,5‐bimpy) and 5‐(2′‐carboxylphenoxy)isophthalic acid (5‐H3cpia). The Co‐MOF possessed a three‐dimensional (3D) porous architecture with the porosity of 22.4% per unit volume. The Co‐MOF@Hemin composite was further constructed via the encapsulation of Hemin into the Co‐MOF material. The constructed Co‐MOF@Hemin exhibited satisfactory peroxidase‐like activity through catalytic oxidation of the colorless peroxidase substrate 3,3,5,5‐tetramethylbenzidine (TMB) to a blue‐colored oxTMB in the presence of H2O2. Hence, the detection of H2O2 was achieved with a wide linear range from 0.005 to 0.5 mM (R2 = 0.992) and a low detection limit of 1.26 μM. More importantly, the peroxidase‐like Co‐MOF@Hemin was suitable for the sensitive and selective detection of glucose under the presence of glucose oxidase (GOx), which reduced O2 to H2O2. This analytical procedure for the detection of glucose had a linear range from 0.3 to 3 mM (R2 = 0.997), with a detection limit of 49 μM. The experimental results display the broad application prospects of the enzyme‐based MOFs in green and selective targets analyses.
