WebApr 7, 2024 · The obvious change in the contrast in the amorphous carbon region indicates that the pyrolysis reaction occurred in the carbon portion, and it could have been catalyzed by a single-atom Au catalyst, thus demonstrating that single-atom Au and NPG co-catalyzed pyrolysis reactions. WebAn enzyme helps catalyze a reaction by decreasing the free energy of the transition state. As a result, more product will be made because more molecules will have the energy necessary for the reaction to occur and the reaction will occur at a faster rate.
