Quantitative Evaluation of Catalytic Reduction via Temperature-Programmed Reduction
Temperature-programmed reduction (TPR) is a versatile technique widely employed for the quantitative analysis of catalytic materials. In this method, the temperature of a catalyst sample is gradually increased while a reducing gas, such as hydrogen, is passed over it. The degree of hydrogen consumed at different temperatures provides valuable information about the distribution of the active sites present on the catalyst surface. TPR profiles can reveal crucial details regarding the reduction behavior of catalysts, including their reduction temperature. By analyzing the shape and position of the TPR peaks, researchers can gain insights into the morphology of the catalyst and its ability to facilitate catalytic reactions.
Quantitative analysis of TPR data is crucial for understanding the performance of catalysts. Several methods have been developed for the quantitative assessment of TPR results, including peak area integration and peak height correlation.
