Harnessing single-atom catalysts for CO₂ electroreduction: a review of recent advances

Abstract

We use an alchemical furnace as the main concept, with three pillars representing the general synthesis strategies for SACs. The four “elixirs” within the furnace chamber represent the diverse regulation strategies for SACs in CO2RR applications.

Customizing catalyst surface/interface structures for electrochemical CO2 reduction

“…The incorporation of axial coordination, leading to the formation of a penta-coordinated structure, plays a pivotal role in regulating spin states and electronic properties, such as the d-band centers of the metal sites. 45 In this context, Chen et al successfully synthesized a Fe 1 N 4 –O 1 site with axial O coordination using a rapid pyrolysis and controllable activation strategy. 26 XAS and AC-HAADF-STEM confirmed this unique coordination structure.…”

Recycling and repurposing of waste carbon nanofiber polymers: a critical review

“…However, advanced nanomaterials, such as metal–organic frameworks (MOFs), covalent organic frameworks (COFs), and graphene, typically exist in forms like discrete powders or nanoparticles. 15–17 Their scalability, continuity, and stability often leave much to be desired when it comes to large-scale industrial applications. Carbon nanofibers (CNFs), integrating the advantages of fibrous and porous structures, occupy a unique niche within this context.…”
