Abstract
This work reports the study of n-butanol thermodesorption from Eu(1, 3 and 5%)-incorporated MCM-41 samples, which was done to verify the thermogravimetric (TG) method for estimation of adsorption properties such as the specific surface area and the volume of primary mesopores for nanoporous materials. The materials studied were synthesized under hydrothermal conditions using a surfactant templating route. The high-resolution TG/1st DTG/2nd DTG curves were obtained in the range from room temperature to 300 °C with heating rate of 5 °C/min in flowing nitrogen. The values of the mesopore volume and specific surface area obtained from the TG data are in good agreement with those evaluated from low-temperature nitrogen adsorption isotherms. In addition, this study shows the importance of the 1st DTG and 2nd DTG curves in the evaluation of the mesopore volume and specific surface area for ordered mesoporous materials.
