Abstract
A method for measuring activation energy of a catalyst is disclosed, which includes obtaining a resonant frequency change-time curve using an integrated self-heating resonant cantilever (), converting the resonant frequency change-time curve into a resonant frequency change-temperature curve, converting the resonant frequency change-temperature curve into a coverage-temperature curve, obtaining a coverage change rate-temperature curve by performing first-order differentiation on the coverage-temperature curve, obtaining relevant parameters corresponding to local minimum values from the coverage change rate-temperature curve, and substituting the relevant parameters into calculation formulas to obtain a desorption rate constant of the catalyst and a desorption activation energy of the catalyst. It can be seen that the present disclosure simply requires programmed heating in terms of operating on the samples, which is fast and convenient. In addition, the method also has other advantages, such as, accurate measurement results, low consumption of samples, and low price.
