A pore excuse for selectivity: The two-electron oxygen reduction reaction (ORR) selectivity is independent of the micropore surface fraction (f_micro) in a rotating ring-disk electrode (RRDE) but correlates negatively to f_micro in a flow cell (FC). The inconsistency results from the different reaction microenvironments in the RRDE to and the FC.

孔结构对氮掺杂碳材料中双电子氧还原反应的影响：旋转环盘电极与流通池

选择性的孔借口：双电子氧还原反应 (ORR) 选择性与旋转环盘电极 (RRDE)中的微孔表面分数 ( f _micro ) 无关，但与流通池 (FC) 中的f _micro负相关）。这种不一致是由于 RRDE to 和 FC 中不同的反应微环境造成的。
