报告摘要：
As two most prominent institutions in southern China, Xiamen University and The Chinese University of Hong Kong (CUHK) have a lot in common. They have established the same level of academic prestige, and both campuses have breathtaking views. Interestingly, there is a genetic link between the two places. Soon after becoming the Head of CUHK’s United College in 2012, I found out that 20% of the College DNA could be traced to Xiamen University. By the way, I was born in a village just 50-min away from Xiamen. This is truly a homecoming visit for me, and I have many stories and photos to share.
Photocatalysis is an emerging technology for solar-induced chemical conversion and pollution treatment. The second part of my presentation will start with a historical review of the technology. This will be followed by the development of photocatalysts for a sustainable future. Photocatalysis can even help us understand the past. The original atmosphere of the Earth was rich in methane and ammonia, and that could be considered as sources of carbon and nitrogen. We have confirmed that a nitrogen-doped carbon photocatalyst could be obtained directly from NH3 and CH4 gases by plasma-enhanced chemical-vapor-deposition. This would suggest that photocatalysis might play an important role in the chemical evolution of the atmosphere. Besides the current state of development, the future prospects of photocatalysis will also be discussed.
