Photoreforming of PET waste via single-atom catalysts

Single-atom catalysts (SACs) can play a decisive role in the photochemical upcycling of plastic waste. In this issue of Chem Catalysis, Lu and co-workers present an efficient Cu/TiO₂ SAC for the photoreforming of polyethylene terephthalate (PET) into organic acids, alongside the generation of H₂.
