study employed a fullereneextractionresidue as a starting material to construct WGLs. The oxidation of the material at 600 °C exposed the WGLs by removing the surrounding amorphous moieties. Transmission electron microscopy (TEM) observations revealed the formation of WGLs by oxidation treatment at
maximum specific ORR activity after 1 h of oxidation time. WGLs were found to lower the heat of adsorption for O2 and to increase the occurrence of heterogeneous electron transfer.

diamond phase, nitrogen, boron, phosphorus, sulfur, and transition metals like iron and cobalt. Such WGLs can be obtained from fullerene-related materials. We selected a commercial carbon, Nanom Black, which is a fullereneextractionresidue from a fullerene soot prepared by a combustion method [40]. The
