a decreasing trendno p-value reported

The highest Q st value of the best-performing NKCS-3 is only 19.19 kJ/mol. It is notable that as the CO 2 adsorption capacity increases, the Q st value shows a decreasing trend, indicating that the surface of the adsorbent material prepared in this study has heterogeneity.
