Enhancement of photocatalytic degradation of dimethyl phthalate with nano-TiO2 immobilized onto hydrophobic layered double hydroxides: A mechanism study

► The reconstructed organic LDHs are consisted of the interconnecting nano-flakes. ► It is confirmed that organic LDHs/TiO2 composites are combined together by chemical bonds. ► The organic LDHs with flaky structure effectively enrich DPM onto the composite. ► The abundant external hydroxyl groups of organic LDHs promote the production of ·OH. ► TiO2 immobilized onto organic LDHs greatly enhances the photodegradation of DMP.
