On the characterization of acidic and basic surface sites on carbons by various techniques

Active carbons of different origins have been oxidized with H O and (NH ) S O and their oxygen surface complexes 2 2 4 2 2 8 have been characterized by TPD, classical titration following Boehm’s method and by neutralization calorimetry. The net enthalpies of neutralization, determined by immersion calorimetry into NaOH and HCl 2 N lead to 241.161.8 and 21… CONTINUE READING
