Understanding the effects of adduct functionalization on C60 nanocages for the hydrogen evolution reaction.
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.
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.
