The adsorption kinetic behavior at 0, 20, 60, and 100 °C on the ZSL sample for N 2 O is presented in Figure 3.These results show that the adsorbed amount and the adsorption rate diminish with increasing temperature, as in the case of the ZAPS sample. It can be seen that the adsorbed amounts of N 2 O on the ZSL sample is lower than that on the
