Abstract:
The design and engineering of material interfaces have revolutionized the field of photocatalysis, unlocking new possibilities for environmental remediation. This talk explores cutting-edge strategies to optimize interfacial properties, enhancing photocatalytic efficiency, selectivity, and stability for diverse applications such as water purification, CO2 reduction, green hydrogen generation and pollutant degradation. Key advancements include the development of heterojunction systems, such as Z-scheme and type-II structures, which facilitate efficient charge separation and improved redox activity. Interface engineering techniques, such as atomic-level doping, strain modulation, and surface functionalization, further tailor electronic and optical properties to extend visible light absorption and minimize charge recombination. The integration of up-conversion materials into semiconductor interfaces enables broader solar spectrum utilization, enhancing performance under real-world conditions. Despite ongoing challenges in scalability, recyclability, and selectivity, the fusion of artificial intelligence, hybrid systems, and novel materials such as covalent organic frameworks (COFs) points to a promising future for photocatalysis. These advancements underscore its potential as a cornerstone for sustainable environmental technologies.
