We have prepared the amphiphilic molecular catalyst [Co^III(L^OC₁₈)(pyrr)₂]ClO₄ (1), where L^OC₁₈ is the deprotonated form of N,N′-[4,5-bis(octadecyloxy)-1,2-phenylene]dipicolinamide. Species 1 can be anchored onto a carbon black support to yield the assembly [email protected], which can catalyze water oxidation at an affordable onset overpotential of 0.32 V, with a current density of 10 mA/cm² at 0.37 V. Moreover, [email protected] displays TOF = 3850 h^–1. A mechanism is proposed based on the experimental and density-functional-theory-calculated data.

两亲分子钴催化剂在炭黑上的固定化，以进行配体辅助水氧化

我们制备了两亲性分子催化剂[Co ^III（L ^{OC ₁₈}）（pyrr）₂ ] ClO ₄（1），其中L ^{OC ₁₈}是N，N '-[4,5-双（十八烷基氧基）- 1,2-亚苯基]二吡啶甲酰胺。种类1可以锚定在碳黑载体，得到装配[电子邮件保护]，其可在一个合理的发病超电势0.32的V催化水的氧化，用10毫安/平方厘米的电流密度²在0.37 V.此外，[电子邮件保护]显示TOF = 3850 h ^–1。根据实验和密度泛函理论计算的数据，提出了一种机理。
