How does Temperature Programmed Reduction (TPR) work?
TPR is used to study the reduction behavior of metal oxides and other reducible materials. In TPR, a sample is exposed to a reducing gas mixture (commonly H₂) while the temperature is steadily increased. The reduction of the sample results in the consumption of the reducing gas, which is monitored by a detector. TPR helps identify reducible species, reduction temperatures, and the number of reducible sites. It is particularly useful for characterizing supported metal catalysts and mixed metal oxides.
