This project develops an innovative fabrication strategy for advanced photocatalyst thin films used in sustainable energy conversion reactions (including H2 generation, C2 – C3 hydrocarbon production). By combining heterostructure materials, plasma treatment, and advanced synthesis process, it develops novel photocatalytic devices with outstanding properties, resulting in superior energy conversion performances. The project also harnesses solar-driven chemistry conversion, contributing to the acceleration of green energy production technology and addressing both global energy crisis and environmental issues.
