| Abstract | ||
| In order to have a sustainable and a clean environment, green chemistry is crucial in today's society. The creation and improvement of iron oxide nanocatalysts for the effective reduction of organic dyes in aqueous solutions is presented in this study. The iron oxide nanocatalysts were prepared using clove and green coffee extract and characterized using advanced techniques such as XRD. The XRD analysis shows the formation of hematite and magnetite forms of iron oxide after calcination at 550 °C. The samples which prepared without calcination have amorphous structures. By producing hydrogen from NaBH4, which was utilized in the reduction of organic dyes (Methylene blue and Remazol red), the sample's catalytic activities were assessed. The results confirmed that iron oxide which prepared using green coffee extract and calcined at 550 °C has the highest reduction activity compared with the other studied catalysts according to its small crystal size and high surface area. Also, the iron oxide has good stability and durability after multiple runs for reduction of remazole red dye | ||
