Studying the reactions between gaseous molecules are not only of great significance to promote the development of industry, agriculture and economy, but also play a special role in the construction of condensed chemistry. Under normal conditions, gaseous molecules exist in a dispersed state. Because the stability of the structure of gaseous molecules, in most cases, the reactions between them can only occur under the “activation” of the catalyst with a specific composition and structure. In this paper, we list five simple examples to illustrate that the occurrence, progress and results of gaseous intermolecular reactions are subject to or even completely determined by the characteristics, composition and multi-level structure of the catalysts with specific condensed matter state under reaction conditions. In addition, we also list another reaction route in this paper, that is, under extreme reaction conditions such as high pressure, ultra-low temperature, laser, plasma and supercritical, the electronic and geometric structures and “states” of a few gaseous molecules will change, resulting in the specific condensed matter chemical reactions.
