Abstract With the increasing use of polylactic acid (PLA), more attention is turning to its post‐treatment. Current methods such as natural decomposition, composting, and incineration are limited by significant carbon dioxide emissions resource waste. Here, an efficient electrocatalytic conversion approach presented transform PLA waste into high‐value chemicals, particularly potassium acetate (AA‐K). By combining experimental theoretical calculation, a high‐performance catalyst Ni(Co)OOH developed, which exhibits current density 403 mA cm⁻ 2 at 1.40 V (vs RHE) with 96% Faraday efficiency for AA‐K in electrooxidation lactate (LA‐K, product degradation KOH). Through situ spectroscopy techniques functional theory calculations, structural regulation catalyst, reaction pathways elucidated. Further experiments demonstrate superior catalytic performance industrial‐scale tandem system. In h electrolysis, 320 g produces 232 L H₂, yielding 1200 97% purity after neutralization drying. The system demonstrates high (approaching 97%) diverse real forms, including powder, cups, fibers, cloth. This research provides scalable sustainable upcycling.

The rational design of heteroatomic sites with synergistic electronic modulation remains a critical challenge for achieving bifunctional oxygen electrocatalysis in sustainable energy technologies such as fuel cells and metal-air batteries. Herein, triatomic Fe2BiN5 configuration embedded nitrogen-doped carbon (Fe2BiN5/C) atomically dispersed FeN2-BiN-FeN2 vacancy-rich structures is synthesized via pyrolysis etching strategy. architecture endows Fe2BiN5/C exceptional activity, delivering high reduction reaction half-wave potential 0.918 V an evolution overpotential 245 mV at 10 mA cm-2, surpassing Pt/C RuO2. In situ X-ray absorption fine structure Raman spectroscopy reveal dynamic structural during electrocatalysis, where Fe acts the primary active center Bi regulating electron distribution long-range interactions, thereby optimizing adsorption/desorption energetics intermediates. theoretical calculations further elucidate that Bi-induced p-d orbital coupling leads to alteration d-orbitals level, downshift d-band center, weaken binding strength oxygen-based intermediates, reduced barrier electrocatalysis. This work provides understanding site p-block metal modulators transition-metal atoms toward enhanced catalysis.
