Latest Patents

One of Pengcheng Xu's key patents is titled "Method for measuring activation energy of catalyst." This patent describes a novel approach that involves obtaining a resonant frequency change-time curve using an integrated self-heating resonant cantilever. The method converts this curve into a resonant frequency change-temperature curve, which is further transformed into a coverage-temperature curve. By performing first-order differentiation on the coverage-temperature curve, a coverage change rate-temperature curve is obtained. Relevant parameters corresponding to local minimum values are extracted from this curve, allowing for the calculation of a desorption rate constant and desorption activation energy of the catalyst. This method is advantageous due to its simplicity, speed, accuracy, low sample consumption, and cost-effectiveness.
