Synthesis of MoO3 microrods via phytoconsituents of Azadirachta indica leaf to study the cationic dye degradation and antimicrobial properties

Abstract

This work is to report an environmental benign route for the fabrication of MoO3 (MO) microrods using leaf extract of Azadirachta indica. The optical, structural, compositions and specific surface area properties of the MO microrods were characterized by UV-DRS, PL, FT-IR, XRD, SEM, EDX, and BET technique. Methylene blue (MB) dye was used to assess the photocatalytic activity of Azadirachta indica leaves modified MoO3 (AzI-MO) microrods under visible irradiations. Controlling various parameters such as AzI-MO dosage, initial MB concentration, and pH value of (cationic dye) MB solution can lead to the enhancement of the photocatalytic degradation of the microrods. The pseudo-first order kinetics was followed by AzI-MO. The antimicrobial performance of MO and AzI-MO were tested, and it shows tremendous activity against gram positive, gram negative and fungal strain.
