Overcoming catalyst deactivation with in-situ electrochemical regeneration in packed-bed reactors enabling long-lived wastewater purification

Nature Communications, Published online: 10 August 2026; doi:10.1038/s41467-026-76638-6 A conductive packed-bed reactor integrates continuous catalytic oxidation with in-situ electrochemical regeneration. The system uses electrically switchable wettability to reduce foulant adhesion and enhance the conversion and separation of •OH-mediated polymeric products.
