Heterogeneous chemistry

Heterogeneous chemistry describes reactions between compounds in different aggregation phases. Heterogeneous chemical reactions take place e.g. between gases and solid ENMs. Some reactions take place  only under the influence of radiation, and reaction products may be released in gas phase or be absorbed to aerosols.
