Abstract

Leather by-product wastes are significant ecosystem pollutants. Consuming these wastes to prepare valuable products is a noble target. In this work, a trial to consume chrome shavings to prepare finegrade manganese oxide nanoclusters via a low-cost co-precipitation method was achieved. The coprecipitation was enhanced by developing the nanomaterial over chrome shaving leather waste. Manganese acetate purified powder was used as a starting material. The synthesised nanoclusters of manganese oxide were characterised by means of X-ray diffraction. The fine-grade prepared sample has been investigated by Scanning Electron Microscope (SEM) and Differential Thermal analysis. The crystalline size of the synthesised manganese oxide nanoparticle was obtained from X-ray diffraction, the sizes of particles ranged from 100 to 300nm. Therefore, the study establishes a scientific basis for the use of chrome shavings as a primary surface in the co-perception process for obtaining metal oxide nanoparticles.
