Abstract:It is a micro innovative design of CO reduction experiment of Fe2O3 ,which two branch test tubes are used respectively as the reaction vessel and as the device for testing CO2 and the collector vessel so that it makes possible to use less a- mount of dosage of chemicals in the experiment. The experiment reaction is rapid and full; the phenomenon is visible; the CO obtained in the action is not only the reactant, but also the energy provider of the experiment when it is kindled to recollect the tail gas, which makes it possible that in the whole process of the experiment no CO is directly discharged thus the energy con- sumption is reduced and the environment protected; the preparation of CO and its properties are both observed in one single experi- ment thus the integration of the two is realized; this innovative design makes the ideology of green chemistry education a reality.
