Abstract
Visible light-mediated reactions have emerged as sustainable synthetic strategies due to mild conditions and high selectivity. In this talk, I will describe a photothermal depolymerization approach that is general to numerous polymers with high selectivity. We identified a bio-derived porous carbon material as a high-surface-area photothermal agent that does not require direct incorporation into polymer resin. Using low carbon loadings, we successfully depolymerized a wide range of polymers. This method was broadly applicable to post-consumer plastics without preprocessing and is readily scalable, demonstrating the versatility of this closed-loop chemical recycling approach. In addition, I will discuss photo-redox mediated ring-opening metathesis polymerization.
