Key Points

To investigate the CO stretching frequencies on a Rh/Fe3O4 single-atom catalyst using high-resolution techniques.
Utilized high-resolution infrared spectroscopy to analyze CO stretching frequencies.
Employed near-ambient-pressure scanning tunneling microscopy to visualize the catalyst at the atomic level.
Successfully assigned CO stretching frequencies with site-resolved precision on the catalyst surface.

Implication

Model demonstrates site-resolved assignment of CO stretching frequencies in a single-atom catalyst, suggesting high effectiveness.

Abstract

A model Rh/Fe 3 O 4 (001) single-atom catalyst enables site-resolved assignment of CO stretching frequencies.
