As global concerns over energy consumption and environmental pollution escalate, the need for sustainable energy sources becomes paramount. Solar energy and hydrogen are identified as clean alternatives with significant potential in reducing greenhouse gas emissions and combating climate change. Solar-driven water splitting to generate hydrogen and oxygen presents a promising avenue to limit the reliance on fossil fuels. The utilization of nanoscale semiconductors, particularly quantum dots (QDs), has emerged as a key focus for enhancing the efficiency of photocatalytic systems in water splitting processes. The unique properties of QDs, such as quantum confinement effects and tunable electronic and optical characteristics, make them highly effective in light harvesting and charge carrier dynamics. By leveraging the advantages of QDs and their composites, researchers aim to achieve higher solar-to-hydrogen efficiency, thereby advancing the field of renewable energy. Recent developments highlight the synthesis of QDs for solar light-assisted water splitting applications, emphasizing the importance of efficient photocatalysts in achieving sustainable hydrogen production. The review article underscores the significance of integrating quantum dots into photocatalytic systems and discusses the latest progress in this area, paving the way for innovative solutions in the realm of clean energy technologies.
