Application of palladium nanoparticle‐decorated <scp><i>Artemisia abrotanum</i></scp> extract‐modified graphene oxide for highly active catalytic reduction of methylene blue, methyl orange and rhodamine B

Abstract

A green palladium‐based catalyst supported on Artemisia abrotanum extract‐modified graphene oxide (Pd NPs/RGO‐ A. abrotanum ) hybrid material has been used as a recoverable and heterogeneous nanocatalyst for the catalytic reduction of various dyes, including methylene blue, methyl orange and rhodamine B, in the presence of NaBH 4 as reducing agent in aqueous medium at room temperature. With the help of UV–visible spectroscopy, the catalytic reactions were investigated. According to the results, these reactions followed the pseudo‐first‐order rate equation.
