tpd (temperature programmed desorption)

How Can TPD Data Be Analyzed?


The analysis of TPD data involves several steps:
Peak identification: Identifying peaks in the TPD spectrum corresponding to different desorbed species.
Quantitative analysis: Calculating the area under the peaks to determine the amount of gas desorbed.
Activation energy calculation: Using models such as the Redhead equation to estimate the desorption activation energy.
Comparative analysis: Comparing TPD spectra from different catalysts or under different conditions to draw conclusions about catalytic behavior.
