Design and Development of a Bio Catalytic Devise for Air Pollutant Adsorption


Air pollution is considered as one of the largest environmental health threats in the world. Scientists and researchers have been working tirelessly to reduce it using existing or novel materials. Use of porous solid adsorbent materials is being studied extensively right now. Because of its large specific surface area, abundance of functional groups, and strong adsorption capacity, activated carbon is widely used to treat various types of carbon-based gases for post-combustion CO2 capture from exhaust systems.
Activated carbon captures CO2 mainly through physical adsorption due to the characteristics of surface structure and pore structure.The capacity of the materials can be further enhanced and made more specific through various surface treatment methods. The incorporation of metal/metal oxides or the addition of acidic/basic functionalities improves the pollutant removal capacity.
The objective of this project is, hence, to design a catalytic chamber to house the bio-catalytic material which is obtained from bamboo residue converted into activated charcoal and doped with MgO Nanoparticles.The designed model is then fabricated to test the prototype’s adsorption efficiency for different gases which are emitted from the exhaust system of automobiles.
