CeF₃/Co₃O₄ Heterojunction Enabled Reconstruction Regulation for Selective and Efficient Electrocatalytic Cleavage of Lignin Cβ–O–4 linkage

Abstract

The efficient cleavage of Cβ–O–4 linkage is crucial for the high-value utilization of lignin. In this study, we developed a CeF3/Co3O4 heterojunction catalyst. The heterojunction facilitated the reconstruction to generate CoOOH, promoting O₂⁻ formation. Thus, it enabled efficient Cβ–O–4 cleavage for both lignin model compounds and native poplar lignin.
