[Abstract]
Organic polymeric photocatalysts have been attracted scientists’ interests during past years due to their low-cost, tunable bandgaps and energy levels, and promising photocatalytic performance. Making the traditional hydrophobic polymeric photocatalyst into nano-particles with size less than 100 nm, so-called polymer dots (Pdots), has shown significantly enhanced photocatalytic activity. Rational design of organic polymers is one of strategies to improve photocatalytic performance for hydrogen production. Moreover, making heterojunction Pdots can efficiently separate photogenerated charges within Pdots as well as utilize energy transfer process to enhance the light harvesting efficiency. In this talk, I will discuss our research achievements in optimization of polymer structures on Pdots photocatalysis, study of photocatalytic mechanism in heterojunction Pdots systems and applications of Pdots in bio-hybrid photocatalytic systems.
