CeF3/Co3O4 heterojunction enabled reconstruction regulation for selective and efficient electrocatalytic cleavage of the lignin Cβ–O–4 linkage

Abstract

The efficient cleavage of the C_β–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 reconstruction to generate CoOOH, promoting O₂⁻ formation. Thus, it enabled efficient C_β–O–4 cleavage for both lignin model compounds and native poplar lignin.
