Photocatalytic degradation of anionic and cationic dye by Zn/Al-CO3 layered double hydroxide 2d materials

Abstract

Accelerating thrust has been noticed for the last couple of years in the direction of new two dimensional materials for fruitful functional applications. Zn/Al layered double hydroxide (LDH) with intercalated anion carbonate as visible light response photo catalyst was fabricated by co-precipitation method. The as prepared LDH photo catalyst was characterized to reveal the structure and texture. The photo catalysis activity of the 2D materials was studied by degradation of an anionic dye methyl orange and a cationic dye methylene blue. It is found that Zn/Al-CO3 LDH has magnificent performance for the degradation of anionic dye and the efficiency is superior to the performance on cationic dye. The kinetics and mechanism of photo catalytic dye degradation of Zn/Al-CO3 LDH were also discussed. The work presents layered materials by facile synthesis and open up the opportunity for easy and cost effective water remediation.
