Outline of Final Research Achievements |
Surface chemistry of the edge carbons are relevant to a variety of reactions and carbon active sites are key topics for catalytic reactions such as oxygen reduction reaction and hydrolysis of cellulose. Herein, oxidized carbon black and boron-doped diamond powder are used as model catalyst. Carbon black is treated with each of three different oxidizing agents to introduce oxygen-containing functional groups and the resulting oxidized carbon blacks are used as a model catalyst for the hydrolysis of cellulose. This study reveals carboxyl groups and phenol groups, act as catalytic sites with almost equal activity, as long as they are present on the external surface. Moreover, the interaction between the active phase and the boron-doped diamond powder support determines the performance of oxygen reduction reaction when modified with FePc or Fe-C3N4 species as it strongly influences the charge transfer between the support and the active sites.
