Abstract:Dual-atom catalysts (DAC) are deemed as promising electrocatalysts due to the abundant active sites and adjustable electronic structure, but the fabrication of well-defined DAC is still full of challenges. Herein, bonded Fe dual-atom catalysts (Fe 2 DAC) with Fe 2 N 6 C 8 O 2 configuration were developed through onestep carbonization of a preorganized covalent organic framework with bimetallic Fe chelation sites (Fe 2 COF). The transition from Fe 2 COF to Fe 2 DAC involved the dissociation of the nanoparticles… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
