Identifying the impact of the covalent-bonded carbon matrix to FeN₄ sites for acidic oxygen reduction.

ABSTRACT: The atomic configurations of FeN_x moieties are the key to affect the activity of oxygen rection reaction (ORR). However, the traditional synthesis relying on high-temperature pyrolysis towards combining sources of Fe, N, and C often results in the plurality of local environments for the FeN_x sites. Unveiling the effect of carbon matrix adjacent to FeN_x sites towards ORR activity is important but still is a great challenge due to inevitable connection of diverse N as well as random defects. Here, we report a proof-of-concept study on the evaluation of covalent-bonded carbon environment connected to FeN₄ sites on their catalytic activity via pyrolysis-free approach. Basing on the closed π conjugated phthalocyanine-based intrinsic covalent organic p
