摘要

为了通过“Au-S”相互作用调节金属卟啉修饰金电极的微环境，测试了一系列具有不同金属中心（金属效应）和酰胺键（亲水性和高偶极子moment）的酰胺键金属卟啉。重要的是，这些电极在宽pH范围的介质中表现出显著的加速、可调和稳定的电化学催化析氢（HERs）性能。特别是具有双酰胺键的金电极3- ni - sam，具有较高分子亲水性和极性的金属卟啉衍生物表现出最满意的HER性能。并比较了键、金属中心和对映异构体的影响。

Microenvironment modulation of amide-bonded Metalloporphyrins functionalized gold electrodes for accelerating Electrocatalyzed hydrogen evolutions

To modulate the microenvironment of metalloporphyrin modified gold electrodes through “Au-S” interactions, a series of amide-bonded metalloporphyrins with different metal-centers (metal effect) and amide-bonds (hydrophilicity and high dipole moment) were tested. Importantly, these electrodes exhibited significantly accelerated, tunable and stable electrochemically catalyzed hydrogen evolution (HERs) performances over a wide pH range medias. Especially, the gold electrode3-Ni-SAM with a doubly-amide bonds, the metalloporphyrin derivative with higher molecular hydrophilicity and polarity has performed the most satisfied HER performances. Also, the influence of the linkages, metal centers and enantiomeric isomers were also compared.
