Therefore a questionnaire was given to students in 9th, 10th and 11th grade pupils. Questions referred to what happens inside a catalyst with the incoming gases. The misconception of a filter or a further combustion engine could be localized. According to the students the catalyst is equipped with netting which slices the molecules.
