Abstract Nanoscience and technology play an amazing role in environment-related issues. In current years, researchers are in motion towards the eco-friendly, simple, sustainable and cost-effective green chemical methods for synthesizing materials rather than toxic chemical methodology. This article describes a non-hazardous method for synthesizing iron oxide using a flower extract of Avicennia marina. UV–Vis absorption spectrum of iron oxide nanoparticles (FeO-NPs) display a peak in the region of 295–301 nm. The FTIR spectrum of FeO-NPs shows bands at 3354 cm−1, 1630 cm−1, 1380 cm−1 and 610 cm−1. The size and morphology of FeO-NPs were explored using scanning electron microscopy (SEM) and atomic force microscopy (AFM), respectively. From the SEM results, the average size of FeO-NPs is seen to be in the range of 30–100 nm. The grain size of FeO-NPs was studied by XRD. Electrochemical studies were carried out to assess the redox behavior of FeO-NPs. The prepared nanoparticles are used in industrial, dye degradation and control the environment pollution.
