A Bioinspired OH-Sponge Catalyst Enables Ultrawide-Voltage and Durable Electrosynthesis of Glycolic Acid from Plastic Waste

concentration, thus preventing Pt-oxidation and supplies active oxygen species enabling targeted conversion to GA. The resulting catalyst achieves an unprecedented GA selectivity of >95% over an ultrawide potential range of 0.5-1.5 V (vs RHE). It demonstrates exceptional durability, operating stably for over 2000 h in a half-cell and >650 h in a membrane electrode assembly. Techno-economic analysis indicates the process can yield a net profit of approximately $720 per ton of PET waste processed. This work provides a biomimetic design principle that simultaneously addresses the challenges of selectivity, stability, and operational flexibility, advancing the viability of electrochemical plastic upcycling.
