Aerobic substrate oxidation reactions catalyzed by a heterogeneous catalyst can be looked upon as two independent half-cell reactions, anodic substrate oxidation and the cathodic oxygen reduction reaction (ORR). In this context, Fe PANI/C, a well-known catalyst for the ORR, is chosen to validate this hypothesis, wherein the anodic reaction is hydrazine oxidation. Fe PANI/C shows excellent activity in terms of the electrochemical ORR and hydrazine oxidation in both alkaline aqueous and non-aqueous media and taken together the aerobic oxidation efficacy of hydrazine-like small organic molecules is correlated with the electrochemical outcomes.
由非均相催化剂催化的需氧底物氧化反应可被视为两个独立的半电池反应，即阳极底物氧化和阴极氧还原反应（ORR）。在此背景下，选择众所周知的ORR催化剂Fe PANI/C来验证这一假设，其中阳极反应为肼氧化。Fe PANI/C在碱性水溶液和非水溶液中的电化学ORR和肼氧化方面均表现出优异的活性，综合来看，类似肼的小有机分子的需氧氧化效率与电化学结果相关。
