Description :
A metal-organic framework (MOF) is composed of two major components: a metal ion or cluster of metal ions and an organic molecule called a linker. MOFs are easily prepared and we used the room temperature synthetic method of MOF to prepare MOF-5. The observations of properties of MOFs are seen in the areas of catalysis, sorption, separation, luminescence, bioactivity, magnetism, etc. Motivated by the recent discovery of Zn4O(BDC)3 i.e. MOF-5 as a semiconducting material, the application of MOFs in photocatalysis is emerging as an interesting topic since its cavity dimension sits exactly between molecular bio-enzymes and porous solid catalysts. The Zn4O(BDC)3 MOF, has an absorption spectrum that extends to 400 nm and can undergo photochemical processes upon photo excitation of the organic linker. Synthesis of MOF-5 is cheap and convenient and we used it for application on photocatalytic study with methylene blue dye. MOF-5 used as photocatalyst and reacted with methylene blue dye by using Philips light as a source of light for the reaction. Degradation on graph after photocatalytic reaction of MOF-5 and methylene blue shows positive result.
