Photocatalytic and antibacterial performance of iron oxide nanoparticles formed by the combustion method

The present study deals with the synthesis, characterization, and testing of the antimicrobial and photocatalytic activities of hematite ore type iron oxide (alpha-Fe2O3) nanoparticles (NPs) formed by the combustion method that makes use of urea as a fuel. The physicochemical analysis of the formed...
