Here, we report a redox-driven strategy for the direct conversion of gold (Au) ions from electronic waste into spatially organized Au\/MXene nanoarchitectures and electrocatalytic membranes. Ti3C2Tx MXene nanosheets exhibit an Au uptake capacity of 3720 mg g\u20131 at 1 ppm, together with high selectivity in the presence of excess competing metal ions. Mechanistic studies reveal that the Au capture is coupled with spontaneous interfacial redox conversion, where \u223c91% of Au(III) ions are reduced in situ into metallic Au nanoparticles on the MXene surface. Importantly, performing the recovery process in a dispersed colloidal state enables recovery-induced interlayer assembly, producing homogeneous Au distributions throughout the MXene framework after vacuum-assisted membrane formation. In contrast to surface-confined deposition in conventional filtration architectures, the interlayer nanoarchitecture preserves ion-transport pathways and maximizes catalytic accessibility. We further show that ultratrace Au concentrations promote the formation of highly dispersed confined Au domains, enabling efficient electrocatalytic membranes despite substantially lower gold loading. The resulting membranes function directly as flexible binder-free electrodes without additional refining, metal stripping, or catalyst deposition steps. This work establishes a recovery-as-fabrication strategy in which dissolved metal ions are directly transformed into functional nanoarchitectures through coupled redox reduction, confined nucleation, and interlayer assembly.<\/jats:p>","DOI":"10.1021\/acsami.6c14687","type":"journal-article","created":{"date-parts":[[2026,10,12]],"date-time":"2026-10-12T07:01:53Z","timestamp":1791788513000},"page":"56333-56342","source":"Crossref","is-referenced-by-count":0,"title":["Recovery-Induced Spatial Engineering of Au\/MXene Nanoarchitectures for Direct Ion-to-Electrode Conversion"],"prefix":"10.1021","volume":"18","author":[{"given":"Fei","family":"Li","sequence":"first","affiliation":[{"name":"National University of Singapore , ,","place":["Singapore, 117544"]},{"name":"National University of Singapore , ,","place":["Singapore, 117575"]},{"name":"Tsinghua University , , ,","place":["Shenzhen, China, 518055"]},{"name":"University of New South Wales , , , ,","place":["Sydney, New South Wales, Australia, 2052"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qian","family":"Wang","sequence":"additional","affiliation":[{"name":"National University of Singapore , ,","place":["Singapore, 117544"]},{"name":"National University of Singapore , ,","place":["Singapore, 117575"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Artemii","family":"Ivanov","sequence":"additional","affiliation":[{"name":"National University of Singapore , ,","place":["Singapore, 117544"]},{"name":"National University of Singapore , ,","place":["Singapore, 117575"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Jiang","sequence":"additional","affiliation":[{"name":"National University of Singapore , ,","place":["Singapore, 117544"]},{"name":"National University of Singapore , ,","place":["Singapore, 117575"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianhong","family":"Wei","sequence":"additional","affiliation":[{"name":"Tsinghua University , , ,","place":["Shenzhen, China, 518055"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hang","family":"Li","sequence":"additional","affiliation":[{"name":"Tsinghua University , , ,","place":["Shenzhen, China, 518055"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vasyl G.","family":"Kravets","sequence":"additional","affiliation":[{"name":"Manchester University , , ,","place":["Manchester, United Kingdom, M13 9PL"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4109-2672","authenticated-orcid":true,"given":"Alexander N.","family":"Grigorenko","sequence":"additional","affiliation":[{"name":"Manchester University , , ,","place":["Manchester, United Kingdom, M13 9PL"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hengrui","family":"Chen","sequence":"additional","affiliation":[{"name":"National University of Singapore , ,","place":["Singapore, 117544"]},{"name":"National University of Singapore , ,","place":["Singapore, 117575"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-0437-507X","authenticated-orcid":true,"given":"Hong","family":"Huo","sequence":"additional","affiliation":[{"name":"National University of Singapore , ,","place":["Singapore, 117544"]},{"name":"National University of Singapore , ,","place":["Singapore, 117575"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Altantuya","family":"Ochirkhuyag","sequence":"additional","affiliation":[{"name":"National University of Singapore , ,","place":["Singapore, 117544"]},{"name":"Mongolian Academy of Sciences , , ,","place":["Ulaanbaatar, Mongolia, 13260"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Su","sequence":"additional","affiliation":[{"name":"Tsinghua University , , ,","place":["Shenzhen, China, 518055"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kostya S.","family":"Novoselov","sequence":"additional","affiliation":[{"name":"National University of Singapore , ,","place":["Singapore, 117544"]},{"name":"National University of Singapore , ,","place":["Singapore, 117575"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0273-2064","authenticated-orcid":true,"given":"Daria V.","family":"Andreeva","sequence":"additional","affiliation":[{"name":"National University of Singapore , ,","place":["Singapore, 117544"]},{"name":"National University of Singapore , ,","place":["Singapore, 117575"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,10,12]]},"reference":[{"key":"2026102609062717000_cit1","doi-asserted-by":"publisher","first-page":"16174","DOI":"10.1073\/pnas.2000606117","article-title":"Precious metal recovery from electronic waste by a porous porphyrin polymer","volume":"117","author":"Hong","year":"2020","journal-title":"Proc.
