WebN2 adsorption/desorption isotherms of the WO3 samples calcined at 400°C and 500°C are shown in Figure 2. The isotherm (Figure 2 (a)) of WO3-DDA calcined at 400°C could be classified as type IV, characteristic of mesoporous materials[26,43]. In this isotherm, the adsorption amount gradually increased in a range of P/P0 = 0.4 to 0.85, which ... WebNov 15, 2010 · On the basis of the N(2) adsorption isotherms at the two temperatures (77.4 K, 87.3 K), the isosteric heat of adsorption (differential adsorption enthalpies), the differential adsorption entropies, and the integral adsorption entropies of N(2) molecules have been evaluated between θ (coverage)=0.05 and θ=1.50.
