摘要

•Eu-doped ZnO at different Eu content were synthetized by SAS process.•Eu-doped ZnO provides novel defect sites and higher hydrophilicity.•Photocatalytic activity was assessed under UV light.•The optimal Eu content for crystal violet and ferulic acid degradation was 1 mol%.•A lower hydrophilicity induced a higher vanillin selectivity.
