New reactor design improves plastic feedstock synthesis using oxygen and electricity
✦AI Summary

Researchers at Seoul National University have developed a new reactor design that improves the synthesis of plastic feedstocks by controlling local pH levels near electrodes. This method significantly increases the efficiency and selectivity of producing lactones and epoxides.

Why it matters

This advancement could lead to more sustainable and efficient production of essential materials used in plastics, electronics, and pharmaceuticals.

Controlling local pH maintains the supply of reactive oxygen species and reduces product degradation, thereby improving reaction efficiency and selectivity. (Bottom) Reactor design incorporating narrow electrode spacing and electrolyte flow, illustrating how increasing the flow rate reduces local pH deviations near the electrodes.
