Development of Hybrid Photocatalytic Systems Integrating CdS QDs and Metal Complexes

For more than 20 years, quantum dots have provided profound insights into the quantum mechanical principles governing light–matter interactions at the nanoscale. In the field of solar fuels production, quantum dots have become an essential platform for studying quantum-controlled photocatalysis owing to their tunable electronic structures enable precise control of charge separation and redox properties. On the other hand, transition metal complexes have been utilized both as photosensitizers and as catalysts for the photocatalytic conversion, due to their favorable photochemical and electrochemical properties, highly tunable reactivity and selectivity, and structural flexibility. This project focuses on developing a hybrid system integrating CdS quantum dots and metal complexes to promote visible-light-driven hydrogen evolution and CO2 conversion in fully aqueous media. By optimizing the preparation method of hybrid photocatalyst, we aim to control the catalytic activity and stability toward hydrogen evolution and CO2 reduction. By improving solar-to-fuel conversion efficiency, this research directly tackles the global dependence on fossil fuels and the associated carbon emissions, addressing both energy security and climate change mitigation challenges that affect modern societies and industries. Furthermore, collaborations with international partners would enable both institutions to exchange advanced methodologies and strengthen their research capacity for solar fuel production.
