Abstract

Kinetic studies of photo- and photoelectro-catalysis fixation of CO₂ are rare. Herein, a typical CO₂ reduction addition to trans-stilbene is studied. Through Tafel analyses, the reaction rate-determining step (RDS) is identified as the first step of an anion free radical generation from the substrate, and the reaction order is 0.5.
