| Abstract |
Discarded zinc-carbon batteries were effectively recycled into magnetically retrievable nanostructures which can perform dual roles as adsorbent and Fenton-like catalysts. The developed nanostructures were made exclusively from various components of spent zinc carbon batteries. The otherwise thrown-away discarded zinc-carbon batteries were thus given a novel role in water treatment. The adsorbent/catalyst design consists of MnO2 and Fe3O4 cores surrounded by a shell of mesoporous ZnO. The adsorption and Fenton-like catalytic performance of the developed nanostructures were studied in detail by employing Methylene blue (MB), Rhodamine B(RB), Methyl orange (MO), and Congo red (CR) as the model pollutants. Various factors influencing the adsorption and catalytic activity were investigated and a detailed mechanism was thereby proposed for the degradation of model pollutants. Thus, a novel approach of Fenton-like catalyst synthesis was introduced emphasizing the principles of the circular economy. The spent zinc-carbon battery-derived adsorbents/Fenton-like catalysts are found to be highly effective, affordable, easy to use, and easy to regenerate. |
