SAM (self-assembled monolayer)-based Photocatalytic Chip from Immobilized Polytriazoles

A third-generation photocatalytic chip can play an essential role in sunlight-driven dye degradation, hydrogen production, etc. Choice of active substances, as well as fabrication methods, are important for practical utilization of the materials. In this paper, we reported devising a photocatalytic chip using immobilized polytriazoles of diketopyrrolopyrrole (DPP) and zinc oxide for the first time. For immobilization, the self-assembled monolayer (SAM) formation techniques were utilized with superior results. Different methods confirmed efficient immobilization and high grafting density for the SAM technique. Computational models suggested favorable energy parameters for the active materials. Photocatalysis was studied for the degradation of multiple polluting dyes under standard environmental conditions using immobilized polytriazoles.
