Çift Etkili Titanyum Borür Katkılı Metal-Organik Kafes Yapıların Geliştirilmesi

Abstract

The increase in human population and the acceleration of industrialization brings environmental pollution and energy demand. Catalytic oxidation plays an important role in the removal of organic pollutants, which is a critical process in terms of environment. The need for innovative anode materials that will increase the energy density in lithium-ion batteries from energy storage systems is increasing. In this study, it is aimed to develop an innovative material that can be used both as an effective catalyst in the catalytic oxidation of phenol and as a high-performance anode material in lithium-ion batteries. In this thesis, composites containing titanium boride and MIL100 cage structures in different ratios were synthesized by hydrothermal method in order to be used as a catalyst in phenol oxidation and as an anode material in lithium-ion batteries. The structural properties of the obtained composites were investigated using FT-IR, powder-XRD and ICP-OES, and the surface properties were investigated using SEM, SEM-mapping and SEM-EDX. It is observed that both structures are homogeneously distributed in the composites. The catalytic properties of the obtained products were investigated in the oxidation reaction of phenol. To determine the optimum conditions, the pH of the solution, the reaction time, the effect of the peroxide amount and the type of catalyst were investigated. It was determined that the phenol conversion varied according to the composite composition and the highest conversion was 93.8%. The usability of the 10%TiB2@MIL 100 composite, which has the highest catalytic activity, as an anode material was investigated in lithium-ion batteries. It was observed that the formation of the MIL100 composite on titanium boride increased the discharge capacity from 210 mAh/g to 385 mAh/g. As a result, it was observed that the composite formation increased both the catalytic activity and the charge-discharge capacity. An innovative material was developed that brings these two different areas together.
