However, achieving high HANs selectivity under ambient conditions remains challenging. Here we report a facet-engineered Cu electrocatalyst that enables selective hydrogenation of HNBs to HANs. Using p-chloronitrobenzene (p-CNB) as a model pollutant, the Cu catalyst achieves complete p-CNB removal with a 98.9% p-chloroaniline (p-CAN) selectivity. Mechanistic studies reveal that the outstanding performance of Cu originates from an optimal balance between moderate H* generation and facile desorption of the p-CAN product, which promotes efficient \u2212NO2 to \u2212NH2 reduction while effectively suppressing the over-dechlorination of p-CAN. Furthermore, it is found that the Cu(111) facet is intrinsically more active than Cu(200) and Cu(220), attributable to its higher p-CAN desorption ability. Guided by these insights, a Cu(111)-enriched electrode is rationally engineered, exhibiting an ultrahigh Faradaic efficiency of 99.4%. Finally, a tandem device integrating an electrolyzer and an extraction-distillation separation unit is developed, enabling the efficient recovery of high-purity p-CAN product. This study demonstrates a sustainable electrochemical pathway for converting hazardous pollutants into valuable chemicals, advancing low-carbon wastewater treatment and resource recovery.<\/jats:p>","DOI":"10.1021\/acs.est.6c07852","type":"journal-article","created":{"date-parts":[[2026,9,3]],"date-time":"2026-09-03T09:40:57Z","timestamp":1788428457000},"page":"25858-25868","source":"Crossref","is-referenced-by-count":0,"title":["Near-Quantitative\nElectrochemical Upcycling of Halonitrobenzenes\nin Wastewater to Valuable Haloanilines over Facet-Engineered Copper\nCatalysts"],"prefix":"10.1021","volume":"60","author":[{"given":"Xueyu","family":"Liao","sequence":"first","affiliation":[{"name":"East China Normal University , , ,","place":["Shanghai, China, 200241"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fuqiang","family":"Liu","sequence":"additional","affiliation":[{"name":"East China Normal University , , ,","place":["Shanghai, China, 200241"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yinhao","family":"Dai","sequence":"additional","affiliation":[{"name":"East China Normal University , , ,","place":["Shanghai, China, 200241"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9712-0513","authenticated-orcid":true,"given":"Yuankui","family":"Sun","sequence":"additional","affiliation":[{"name":"East China Normal University , , ,","place":["Shanghai, China, 200241"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0041-2817","authenticated-orcid":true,"given":"Alicia Kyoungjin","family":"An","sequence":"additional","affiliation":[{"name":"The Hong Kong University of Science and Technology , , Clear Water Bay , , ,","place":["Kowloon, Hong Kong Special Administrative Region, China, 999077"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7001-6900","authenticated-orcid":true,"given":"Irene M.
