Abstract
In this project, CuCoFe2O4 and CuCoFe2O4-Perlite rod-shaped nanoparticles were first synthesized using fast, low cost and easy methods, and the use of perlite mineral in this compound has been reported. To this purpose, for the synthesis of this nanoparticle, high-efficiency co-precipitation method and salts of cobalt (II) acetate, copper (II) acetate, and iron (II) sulfate were used. The ratio of iron: cobalt: copper in this study was 1: 0.8: 0.2. The HKUST-1 metal-organic framework was then synthesized by hydrothermal method. It was composed once with ferrite nanoparticles and once with ferrite nanoparticles on perlite support, and these composites were named F.MOF and F.P.MOF, respectively. The effect of perlite support on adsorption and catalytic applications for F.P.MOF was determined compared to the case where F.MOF was used. The structure, morphology, optical properties and surface charge of this composite were investigated by FT-IR, FE-SEM, TEM, XRD, EDS, BET and zeta potential methods. After identifying these composites, they were used in two parts: adsorption application and catalytic applications in organic reactions, which in the adsorption application, adsorption of methylene blue and methyl orange organic dyes, and in the organic catalytic applications, the hantzsch and biginelli reactions were examined. Relevant reports were presented in the adsorption application section by UV-Vis analysis and in the organic reactions by FT-IR and NMR analyzes. By drawing the diagram, the maximum adsorption capacity for F.MOF adsorbent and methylene aqueous analytes and methyl orange were 47.63 and 23.82 mg/g, respectively, and for FPMOF adsorbent and methylene aqueous analytes and methyl orange the values of 49.41 and 41.76 mg/g were obtained, respectively. The results show that the maximum adsorption capacity is increased when the adsorbent with perlite support is used because perlite increases the surface area. In the organic Hantzsch and Biginelli reactions, corresponding alcohol was used for the first time in the world. In this section, two synthesized catalysts were compared. Biginelli reaction efficiency using benzyl alcohol for F.MOF and F.P.MOF catalysts was 72% and 80%, respectively. Also, Hantzsch reaction efficiency using benzyl alcohol for F.MOF and F.P.MOF catalysts was calculated to be 76% and 82%, respectively. The results show that the catalyst with perlite support has higher efficiencies due to the larger surface area.
