Cheaper component for greenhouse gas reduction catalyst

Scientists from China have replaced the tungsten oxide in a widely used greenhouse gas reduction catalyst with iron oxide, which improves the selectivity and reduces the cost of the catalyst.

Produced at any combustion site, nitrogen oxides (a mixture of NO and NO2) – common greenhouse gases – are found anywhere from industrial sites to car exhausts and are regulated by a number of international agencies. As such, several catalytic reactions can be used to reduce the amount of nitrogen oxides produced. One of the most common is selective catalytic reduction (SCR), which converts nitrogen oxides into N2 and H­2O using a reducing agent, commonly ammonia, and a catalyst.
