  Metal Organic Framework-5 (MOF-5) can be used for sensing of Volatile Organic Compounds (VOCs). VOCs are emitted from biological sources, paints, coatings, etc. and they pollute the environment thus posing serious health and environmental hazards. MOF-5 is a three dimensional crystalline coordination compound made up of Zn4O inorganic group as the vertex and benzene decarboxylate organic group as the spacer in the unit cell of the crystal. This study reported the synthesis and characterization of MOF-5 and its capability towards sensing of VOCs like ethanol, formaldehyde and acetone. Transmission Electron Micrograph reveals that the synthesized sample is highly crystalline and porous. BET surface area obtained was found to be 230 m2 g-1. MOF-5 was made into pellets of thickness around 3 mm for sensing purposes. The material was found to be sensitive towards ethanol even at concentrations as low as 5 ppm, towards formaldehyde at higher concentrations and towards acetone at concentrations as low as 10 ppm. The order of increase in sensitivity is ethanol>formaldehyde>acetone.
