English
A two-step process combining selective adsorption with phase-transferred electrocatalytic regeneration using defect-engineered Fe-N-doped porous carbon removes emerging contaminants. Cathodically generated H2O2 is activated on Fe-N sites to produce •OH, restoring >90% adsorption capacity without oxidant or pH adjustment. For sulfamethoxazole, energy use was 0.034 kWh log−1 m−3 and CO2 emissions fell 96.9-99.4% versus conventional AOPs.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
水処理・浄化技術の省エネ・低炭素化は、日本の産業排水規制やカーボンニュートラル施策と接点があるが、SSBJ・有報・TCFD開示に直接資する内容ではない。製造業の環境負荷低減技術として参考価値はある。
In the global GX context
This sits in the water-treatment decarbonization space rather than disclosure frameworks like TCFD/ISSB/CSRD. It offers global readers a low-energy, low-carbon alternative to conventional AOPs, relevant to industrial water and pollution-control decarbonization but not to climate disclosure scholarship.

📄 Abstract（原文）
The sustainable management of trace emerging contaminants (ECs) is essential for safeguarding water resources and achieving global carbon-neutrality targets. To address the bottleneck of high energy-consumption and carbon emission caused by the non-selective oxidation of complex organics in conventional advanced oxidation processes (AOPs), we report a sustainable and low-carbon process for ECs removal through a two-step strategy combining selective adsorption and phase-transferred electrocatalytic regeneration using a defect-engineered Fe-N-doped hierarchical porous carbon. Carboxylate-assisted defect modulation constructed hierarchical porosity and enriched pyridinic-N-Fe sites, which not only selectively captured high ionization potentials (IP) contaminants through charge-transfer-driven interactions, but also activated the cathodically generated H2O2 on Fe-N sites to produce •OH to fulfill electro-Fenton (EF) regeneration, restoring over 90% of adsorption capacity without any oxidant addition or pH adjustment. Taking sulfamethoxazole (SMX) as sample EC, the continuous run of the process majority removed SMX with an ultra-low energy consumption (0.034 kWh log−1 m−3) that was only 4.6% and 2.1% of homogeneous EF and electro-oxidation, respectively, while the CO2 emissions reduced by 96.9-99.4% compared with conventional AOPs. Our approach achieves trace ECs purification through a reagent-minimized, cyclic adsorption-regeneration pathway, offering a more energy-efficient and cleaner alternative to conventional oxidation systems and opening new opportunities for sustainable and low-carbon water treatment. This study presents a sustainable, low-carbon strategy that removes emerging contaminants from water through selective adsorption and phase-transferred electrocatalytic regeneration, reducing energy use and carbon emissions.
