AIST ousts exhaust fumes

Japans’ National Institute of Advanced Industrial Science and Technology has developed a reagent that can remove harmful substances from exhaust fumes at much lower temperatures.


Japans’ National Institute of Advanced Industrial Science and Technology (AIST) has developed a reagent that can remove harmful substances from exhaust fumes at much lower temperatures.



The AIST scientists, together with NGK Insulators, have developed a platino-alumina agent that can oxygenate and purify harmful and volatile organic compounds contained in exhaust emissions.



The new agent can reduce the reaction temperature by about 100oC compared to conventional ones, while increasing heat resistance by 200oC.



The group hopes to market the platino-alumina agent, which uses inexpensive aluminium hydroxide as a raw material and is produced in a cost-efficient and simple freeze-dry process.
