Key Findings of the Study:

• The CdS/CeO2 nanocomposite (1:1) demonstrated a 53.73% degradation efficiency for methyl orange dye under visible light irradiation.
• The heterostructured CdS/CeO2 composite effectively separated photoinduced electrons and holes, enhancing photocatalytic performance.
• The composite maintained moderate reusability, with only a 33% performance reduction after four successive cycles.
• The research highlights the synergetic effect of CdS and CeO2 in improving charge separation and extending light absorption into the visible spectrum.

How Does This Technology Work? The nanocomposite works through an advanced oxidation process (AOPs), utilizing hydroxyl radicals (•OH) and superoxide radicals (•O2-) to break down pollutants. The CdS component facilitates visible light absorption, while CeO2 nanoparticles aid in electron transfer, improving degradation efficiency.

External Perspective on Nanotechnology for Water Purification: According to the American Chemical Society (ACS), semiconductor-based photocatalysis is a promising avenue for addressing environmental pollutants. The ability to harness solar energy for water purification aligns with global efforts toward sustainable wastewater treatment.
