　　Abstract 

　　In recent years, organic polymeric photocatalysts have garnered considerable attention from scientists owing to their cost-effectiveness, adjustable bandgaps and energy levels, and promising performance in photocatalysis. Transforming traditional hydrophobic polymeric photocatalysts into nanoparticles with sizes less than 100 nm, known as polymer dots (Pdots), has demonstrated significantly enhanced photocatalytic activity. Employing a rational design approach to organic polymers stands as one of the strategies aimed at augmenting the photocatalytic efficiency for solar fuels production. Furthermore, the creation of heterojunction Pdots facilitates the efficient separation of photogenerated charges within Pdots and leverages energy transfer processes to enhance light harvesting efficiency. During my talk, I will delve into our research accomplishments, which include optimizing polymer structures for Pdots photocatalysis, understanding the working mechanism, exploring heterojunction Pdots systems, and investigating the applications of Pdots in bio-hybrid photocatalytic systems.
