Electrochemical Synthesis of Zn-Al-based Layered Double Hydroxides Intercalated with 4-hydroxy-3-methoxy Cinnamic Acid as a UV-ray Absorbent

摘要

One-step electrochemical synthesis of Zn-Al-based layered double hydroxides intercalated with 4-hydroxy-3-methoxy cinnamic acid as a UV-ray absorbent (Zn-Al/HMCA LDH) was attempted in this study. Among various preparation conditions, it was confirmed that HMCA was intercalated into the interlayers of Zn-Al-based layered double hydroxide (Zn-Al LDH) by potentiometric electrolysis at -1.5 V for 1 h at RT. The Zn-Al/HMCA LDH films prepared on a Pt plate showed an excellent UV-ray absorption property.
