WebDec 17, 2013 · In graphite, each carbon atom is strongly bonded to three neighboring carbon atoms in a plane and the planes of atoms are loosely bonded to each other. The degradation of diamond to graphite is a simple case of the atoms internally rearranging and relaxing to a lower energy state. WebThis study surprisingly found that graphite can mediate direct electron transfer from organics (e.g., sulfamethoxazole (SMX)) to KMnO 4, resulting in high KMnO 4 utilization efficiency, rather than reductive sites of graphite-induced conversion of KMnO 4 to highly reactive intermediate Mn species.
