Photocatalytic Degradation of Rhodamine-B and Water Densification via Eco-Friendly Synthesized CrO and Ag@CrO Using Garlic Peel Aqueous Extract.

The purification and densification of wastewater play an important role in water recycling, especially if the materials used in water recycling are other types of recycled waste. Therefore, considering this view in this study, the biosynthesis of silver-decorated chromium oxide nanoparticles utilizing a wasted (garlic) peel extract is investigated. The aqueous extract of garlic peel (GPE) was treated with silver nitrate, chromium nitrate, and a mixture of silver nitrate and chromium nitrate to synthesize silver nanoparticles (Ag-garlic), chromium oxide nanoparticles (CrO-garlic), and silver-decorated chromium oxide nanoparticles (Ag@CrO-garlic), respectively.
