Abstract
::
: In recent years, energy crisis and environmental pollution have emerged as the most pressing global issues, which have attracted significant attention from scientific community. In the pursuit of renewable energies for future and sustainable remedial methods for environmental mitigation, the photocatalytic technique has been recognized as a promising technology, which can provide long-term solution to these global issues. The photocatalytic method offers distinct advantages in terms of use of renewable energy, environmental compatibility, economy and high efficacy over conventional methods. The photocatalytic water splitting to generate H2 energy over the surface of a semiconductor is considered as a potential alternative to conventional energy sources. Similarly, the photocatalytic oxidation of persistent organic pollutants from aqueous sources using semiconductor photocatalyst is considered as an economic and clean alternative to chemical methods of water treatment. Among several semiconductor materials, the metal organic framework (MOFs) materials have aroused lot of interest in recent years due to their high surface area, tunable pore structure and high photoconversion efficiency. The photocatalytic efficacy of MOFs can be improved significantly by preparing heterojunction materials with metal sulfide and mixed metal sulfide nanoparticles which act as principal visible light absorbing component. In this in this work, we have studied the synthesis and photocatalytic application of UiO-66(Zr) based hetrojunction nanocomposite materials with mixed metal sulfide nanoparticles for potential application in the field of water remediation and H2 energy production. In this seminar, the structural and photocatalytic properties of Zr- metal based UiO-66 MOF materials and their heterostructure systems will be discussed.
