An electrooxidation strategy mediated by reactive oxygen species is proposed to realize the transformation of styrene to benzaldehyde on a Pt anode, with a high selectivity of 89% and faradaic efficiency of 28.8%. Isotopic labelling, electron paramagnetic resonance and radical scavenging experiments revealed that OH˙ and O˙ species, formed anodic water oxidation, play a crucial role in the selective formation of benzaldehyde.
提出了一种由活性氧介导的电氧化策略，以在铂阳极上实现苯乙烯向苯甲醛的转化，选择性高达89%，法拉第效率为28.8%。同位素标记、电子顺磁共振和自由基清除实验表明，阳极水氧化形成的OH˙和O˙物种在苯甲醛的选择性形成中起关键作用。
