Partial thermal atomization of residual Ni NPs in single-walled carbon nanotubes for efficient CO₂ electroreduction.

ABSTRACT: CO₂ electroreduction (CO₂RR) is an important solution for converting inert CO₂ into high value-added fuels and chemicals under mild conditions. The decisive factor lies in the rational design and preparation of cost-effective and high-performance electrocatalysts. Herein, we first prepare a novel f-SWNTs-650 catalyst via a facile partial thermal atomization strategy, where the residual Ni particles in single-walled carbon nanotubes (SWNTs) are partially converted into atomically dispersed NiN₄ species. CO₂RR results show that the competitive evolution hydrogen reaction (HER) predominates on pristine SWNTs, while f-SWNTs-650 switches the CO₂ reduction product to CO, achieving a CO faradaic efficiency (FE_CO)
