Immersion Calorimetry for the Characterization of PD Catalysts Supported on Activated Carbon

Immersion Calorimetry for the Characterization of PD Catalysts Supported on Activated Carbon

Activated carbons obtained from coconut peel were oxidized using hydrogen peroxide. Superficial characteristics of these carbons were determined through N2 and CO2 isotherms and functional groups were characterized by TPD. Finally, the microcalorimetry technique was used in order to obtain the immer...
