Study on synergistic effects of 4f levels of erbium and black phosphorus/SnNb 2 O 6 heterostructure catalysts by multiple spectroscopic analysis techniques

This is the authors' abstract. We don't add key points for this paper.

Visible-light-driven CO 2 photoreduction performance can be improved by utilizing the synergistic effect of BPEr/SNOEr heterostructures, Er single atoms and the Er 4f energy level to facilitate light absorption.
