Four novel two-dimensional porphyrin COFs (M-TP-COF, M = H, Co, Ni and Mn) with donor-acceptor dyads were fabricated and served as electrocatalysts for the oxygen reduction reaction (ORR). The ORR catalytic activity of M-TP-COF was tuned by changing the M atom in the center of the porphyrin backbone. The experimental structure-function relationship was in accordance with the results of density functional theory calculations based on the O-O*-OOH*-O*-OH*-OH route.
制备了四种具有供体-受体二元体系的新型二维卟啉共价有机框架材料（M-TP-COF，M = H、Co、Ni和Mn），并将其用作氧还原反应（ORR）的电催化剂。通过改变卟啉主链中心的M原子来调节M-TP-COF的ORR催化活性。实验得出的结构-功能关系与基于O-O*-OOH*-O*-OH*-OH路径的密度泛函理论计算结果一致。
