Two new mononuclear iron (II) coordination complexes: Fe(L1)2(SCN)2 (1, L1:5-dimethylether-4-(4-methylphenyl)-3-(2-pyridinyl)-1,2,4-triazole) and Fe(L2)3(ClO4)2 (2, L2 :1-ethyl acetate-2-(2-pyridinyl)-imidazole), for the exploration of spin-crossover compounds have been synthesized and characterized. Structural analysis revealed that the framework of complex 1 is featured with 1-D chain structure connected by weak π···π interactions between the adjacent L1 ligands, while complex 2 featured with various kinds of weak intermolecular hydrogen bonding interactions between Fe(L2)32+ cation and ClO4− anion, which lead to a close crystal packing. The intermolecular interactions have shown a significant influence on the physical properties, and magnetic measurements of complexes 1 and 2 in the solid state at the room temperature revealed that the weak intermolecular interactions in 1 resulted in HS (high-spin) state, while the strong interactions in 2 lead to LS (low-spin) state over the whole temperature range.

To improve the dispersion ability of CuO nanoparticles (NPs), their surface was modified by chiral diacids (DAs) containing amino acids. The surface modification process was achieved using ultrasonic irradiation. DA could be absorbed on the surface of CuO. The carboxyl groups of DA may interact with surface of CuO NPs and form covalent bond with it. Interactions between DAs and CuO NPs were investigated by different techniques. The X-ray diffraction patterns proved that modification process does not change the crystalline phase of CuO. The results confirmed successful deposition of the organic functional groups on the surface of NPs.

The combination of rings and two chains forms independent 1D MONT. The I groups of each 1D MONT polythread into two adjacent 1D MONTs to form a (1D → 2D) polythreaded array. 3 shows the undulated 2D (4,4) network and a double-layer hydrogen bonding network. The luminescence and thermal stability were investigated.

Mixed metal oxides (TiO2/WO3) containing polythiophene binder were prepared. The molar ratios of TiO2/WO3/thiophene used for an in situ polymerization were varied from 1/2/0 to 1/2/0.6. Catalytic activities of the metal oxides were studied by following up the degradation of methylene blue under various illumination conditions. With the presence of the polymeric binder in the system, the activity in the dark was induced whereas those under both UV and visible light were maintained. The amount of polymer also played a role. The catalytic activities decreased with increasing monomer content. The results are discussed in light of morphology characterized by TEM-EDX.

The ternary blends consisting of biodegradable polymer-based ternary blends composites were prepared by the solution blending method with glutaraldehyde. Prepared ternary blends were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, and differential scanning calorimetry. Subsequently, the adsorbent activity for heavy metal, chromium, was estimated in terms of the existent initial concentration, adsorbent dose, contact time, and pH. The adsorption study was performed for the pH ranging from pH 4.0 to 8.0. It was observed that the sorption efficiency, increased with increasing the pH of the solution from 4.0 to 5.5. At low pH values of the solution, the amine groups were propagated to various degrees, reducing the number of binding sites available for metal ion uptake so that the extent of chromium uptake is low in the high concentrations of protons. Moreover, the protonation of amine groups is induced an electrostatic repulsion of cations. When the pH of the solution was more than 5.5, the sorption rate began to decrease. Besides, the quantity of adsorbate on absorbent was fitted as a function in Langmuir and Freundlich isotherm. The sorption kinetics were tested for pseudo first- and pseudo second-order reactions. The kinetic experimental data correlated with the second-order kinetic model and rate constants of sorption for kinetic models were calculated and accordingly, the correlation coefficients were obtained. The investigation emphasized that the composite was very effective for the adsorption of Cr (VI).

Mn2+ doped ZnFe2O4 nanocrystals have been successfully synthesized by one-pot autocombustion method. The synthesized MnxZn1-xFe2O4 nanocrystals were characterized by XRD, FT-IR, HR-SEM, TEM, EDX, BET, DRS, PL, and VSM. The results indicated that the prepared spinel MnxZn1-xFe2O4 nanocrystals showed high crystallinity and uniform size distribution with particle-like morphologies. The present study leads to enhance the photocatalytic activity of MnxZn1-xFe2O4 with the addition of TiO2. Having established that spinel MnxZn1-xFe2O4 was photocatalytically active, the mixed oxide catalysts of MnxZn1-xFe2O4 -TiO2 were also tested for the photocatalytic degradation of 4-chlorophenol.

The results indicated that the prepared spinel MnxZn1-xFe2O4 nanocrystals showed high crystallinity and uniform size distribution with particle-like morphologies. The present study leads to enhance the photocatalytic activity of MnxZn1-xFe2O4 with the addition of TiO2. Having established that spinel MnxZn1-xFe2O4 was photocatalytically active, the mixed oxide catalysts of MnxZn1-xFe2O4 -TiO2 were also tested for the photocatalytic degradation of 4-chlorophenol.","PeriodicalId":22118,"journal":{"name":"Synthesis and Reactivity in Inorganic, Metal-Organic, and Nano-Metal Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85165900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
