In Situ Preparation And Immobilization Of Semiconducting Polymer Dots On Microbeads For Efficient And Stable Photocatalytic Hydrogen Evolution

Organic semiconducting polymers dots (Pdots) have recently shown efficient photocatalytic activity for hydrogen evolution in an aqueous phase. However, colloidal Pdots face problems of aggregation and precipitation during the photocatalytic reaction due to unavoidable collisions between particles, thus resulting in a short catalytic lifetime. In this work, in situ preparation of PFBT Pdots on the surface of microbeads is reported. Results indicate that, with this facile method and support of a template, the photocatalytic properties of PFBT Pdots can be highly enhanced.
