摘　　要：Catechol-formaldehyde resin(CFR)is very attractive for H_(2)O_(2) production via the catalytic process.However,the H2O2 formation is accompanied by the oxidation of catechol groups to o-benzoquinone groups on CFR,which will cause irreversible damage to CFR and greatly limit its long-term stable catalytic activity.Herein,CdS/CFR composite photocatalyst with a core-shell structure was synthesized by hydrothermal method.The photogenerated electrons of Cds are used as a powerful driving force for the reversible redox conversion between catechol groups and o-benzoquinone groups on the CFR.
