Abstract

In this work, we use experimental and theoretical techniques to study the origin of the boosted hydrogen evolution reaction (HER) catalytic activity of two pyridyl-pyrrolidine functionalized C₆₀ fullerenes. Notably, the mono-(pyridyl-pyrrolidine) penta-adduct of C₆₀ has exhibited a remarkable HER catalytic activity as a metal-free catalyst, delivering an overpotential (η₁₀) of 75 mV vs. RHE and a very low onset potential of −45 mV vs. RHE. This work addresses fundamental questions about how functionalization on C₆₀ changes the electron density on fullerene cages for high-performance HER electrocatalysis.

了解加合物功能化对C60纳米笼析氢反应的影响。

在这项工作中，我们利用实验和理论技术研究了两种吡啶基-吡咯烷官能化 C60 富勒烯增强氢进化反应催化活性的原因。值得注意的是，C60 的单（吡啶基-吡咯烷）五加合物作为一种无金属催化剂表现出了显著的氢进化反应催化活性，与 RHE 相比，过电位 (η10) 为 75 mV，起始电位非常低，为 -45 mV。这项研究解决了有关 C60 功能化如何改变富勒烯笼上电子密度以实现高性能 HER 电催化的基本问题。

期刊介绍： Nanoscale Horizons stands out as a premier journal for publishing exceptionally high-quality and innovative nanoscience and nanotechnology. The emphasis lies on original research that introduces a new concept or a novel perspective (a conceptual advance), prioritizing this over reporting technological improvements. Nevertheless, outstanding articles showcasing truly groundbreaking developments, including record-breaking performance, may also find a place in the journal. Published work must be of substantial general interest to our broad and diverse readership across the nanoscience and nanotechnology community.
