Allotropic Carbon Nanoforms as Advanced Metal-Free Catalysts or as Supports
Figure 3
Representative example of an ideal time conversion plot for the phenol disappearance in the catalytic Fenton degradation by H2O2 using Au-DNP as catalyst in the dark in the absence of buffers. The reaction is initiated at neutral pH, exhibiting an induction period. Once the reaction starts, there is a decrease in the pH value up to 3.5 due to the formation of polycarboxylic acids that accelerates the reaction.
