What Information Can Be Obtained from TPR Profiles?
The TPR profile, which is a plot of hydrogen consumption versus temperature, provides valuable information about the catalyst. Peaks in the TPR profile correspond to different reduction events occurring at specific temperatures. The position, shape, and number of these peaks can reveal the presence of various reducible species, their interaction with the support, and the strength of the metal-oxygen bonds. Additionally, the hydrogen consumption can be quantified to determine the extent of reduction.
