Synthesis of Metal-Organic Compounds and Their Applications

Abstract

The interest in metal organic compounds has significantly increased in recent years due to their potential for various applications such as gas storage, separation, sensor, photocatalyst, electronics, and etc. As a famous photocatalyst, graphitic carbon nitride has been used because it is abundant and stable in thermal and chemical conditions. However, it has problems, for example, the fast recombination rate of an electron-hole pair and narrow light absorption range. Also, a carbon nanotube is known as one of sensor materials because of their electrical, thermal properties, and high aspect ratio. Nevertheless, sensing properties of the CNT is greatly limited by their lack of adsorption sites. Because of these reasons, those materials have attracted great scientific interests for developing a new method and synthesizing the hybrid materials. In here, two novel synthesis have been employed in this thesis. In the first session, ZnTPyP, which has good light absorption properties under the solar spectrum, was incorporated with the graphitic carbon nitride. The synthesized hybrid material based on ZnTPyP and g-C3N4 have enhanced light absorption range and photocatalytic properties. In the second session, CuBTC, which is one of metal organic frameworks materials, was covered on the carbon nanotube. The CuBTC/CNT was simply synthesized by the filtration process. The large porosity of the synthesized CuBTC/CNT increased the adsorption sites, and it enhanced the sensing properties.
