The invention discloses a technology of a bionic purifier for 
carbon dioxide in fuel vehicle exhaust, and solves the problem that a conventional vehicle three-way 
catalytic converter cannot covert 
carbon dioxide in exhaust or purify PM2.5. Through the use of the 
photosynthesis of green plants and the application of biomimicry and 
catalysis and reaction 
engineering, the 
photosynthesis is artificially imitated, an artificial 
electric field is arranged in a bionic tube by using the residual heat of 
waste gas of a vehicle, and 
kinetic energy and supplied power of the vehicle, a plurality of groups of 
palladium plated 
electrode grids are arranged, and water in the exhaust is ionized into 
hydrogen and 
oxygen under the dual effects of an 
electric potential and 
precious metal; 
hydrogen containing exhaust enters a reactor taking natural 
zeolite as a medium, the medium has high adsorption, 
filtration and 
catalysis characteristics; 
carbon dioxide and 
hydrogen are synthetized into a 
sugar organic matter, byproduct 
oxygen is escaped, and the carbon dioxide conversion and PM2.5 
filtration are realized. In order to prevent inactivation of reaction products due to deposition, a washing blow-down 
system is designed. The bionic purifier has a 
noise elimination function, and can replace a conventional secondary 
noise eliminator. The bionic purifier has great practical significance in fields of manufacturing of vehicles and environment protection.
