| Abstract |
Controlling industrial effluent and treating it with improvised technologies continues to be a dominant research topic in the scientific community. In this study, the concepts of circular-economy and control-of-waste-by-waste were applied to the synthesis of a photocatalyst composite composed entirely of waste resources, namely waste rust (Fe2O3) and seashells (CaO). The ratio of these two waste materials was optimized to yield a composition 10% Fe2O3/90% CaO (10-FC) that was effective in decolorizing 85% of methylene blue in 60 min, with a formal quantum efficiency of 0.27% in direct sunlight. The heterogeneous photocatalyst was characterized by UV-Vis/NIR, SEM and XRD and is proposed to follow Langmuir-Hinshelwood kinetics and Z-scheme mechanism of charge transfer. Here, waste products were integrated and utilized to create a resource that is recommended for the treatment of dye effluent using a renewable energy source. This research aims to identify elements present in waste dumps and create a valuable resource from them to promote sustainable practices. |
