Calorimetric Methods for the Characterization of Porous Materials presents the calorimetric methods that can be used in the characterization of porous materials using chemical thermodynamics. Among these materials, catalysts, supports and adsorbents (such as Activated Carbon, Metal-Organic-Frameworks, SBA-15, Zeolites, Graphene, Graphite, Carbon Foams) are presented. In addition, the use of calorimetry in the study of catalytic reactions in different phases is presented, applicable to air and wastewater treatment, clean and renewable energies, green chemistry, as well as energy production and storage (CO2, CH4 and H2 at high pressure). The chapters summarize the basic concepts of thermodynamics and kinetics alongside the use of experimental techniques such as thermal analysis and calorimetry to answer practical questions. Information is given about different calorimetric methods that can be used in studies aimed at characterizing the physicochemical properties of adsorbents, supports and solid catalysts, as well as the processes related to the adsorption-desorption phenomena of the reactants and/or products of catalytic reactions. The thermodynamic and kinetic aspects of catalytic reactions are also shown to be effectively investigated by calorimetric methods to achieve a better understanding of the sequence of the elementary steps in catalytic reactions. Calorimetric Methods for the Characterization of Porous Materials is written for graduate level students and postdoc researchers in chemistry, chemical engineering, and materials science.
