Crystalline α-FE2O3 nanoparticles and method of making and use thereof in photodegradation of organic pollutants, as a photocatalyst and as an antibacterial composition

Abstract

Crystalline α-Fe2O3 nanoparticles prepared by ultrasonic treatment of a solution of an iron (III)-containing precursor and an extract from the seeds of a plant in the family Linaceae. The crystalline α-Fe2O3 nanoparticles have a spherical morphology with a diameter of 100 nm to 300 nm, a mean surface area of 240 to 260 m2/g, and a type-II nitrogen adsorption-desorption BET isotherm with a H3 hysteresis loop. The crystalline α-Fe2O3 nanoparticles have a band gap of 2.10 to 2.16 eV and a mean pore size of 7.25 to 9.25 nm. A method for the photocatalytic decomposition of organic pollutants using the crystalline α-Fe2O3 nanoparticles. An antibacterial composition containing the crystalline α-Fe2O3 nanoparticles.
