• oxidation of benzyl alcohol to benzaldehyde and in the epoxidation of propene with nitrous oxide. Moreover, in experimental and theoretical works [9], it was clearly shown that the partial substitution of copper with gold leads to a change in the physicochemical properties in many cases. For example, there

For instance, gases such as nitrous oxide or ethane have low critical values, but explosive mixtures can be generated
