Synergistic Effects of Electricity and Light for Efficient Iron-Catalyzed Recycling of Polystyrene Waste. [PDF]

Angew Chem Int Ed Engl
The synergistic interplay of electricity, light and earth‐abundant, nontoxic iron catalysis allowed for the efficient recycling of post‐consumer polymers into value‐added products. This robust depolymerization strategy was viable on multigram‐scale, where the cathodic hydrogen evolution reaction presents an attractive opportunity for a green hydrogen ...
