Herein, an S-scheme heterojunction consisting of S-doped TiO2 nanotubes and g-C3N4 was successfully constructed via an annealing-assisted interfacial engineering strategy. Comprehensive band structure analyses using Mott\u2013Schottky measurements, valence band X-ray photoelectron spectroscopy, and Kelvin probe force microscopy confirmed the formation of an S-scheme heterojunction between S-TiO2 and g-C3N4. The experimental results revealed a favorable band alignment and the establishment of an interfacial built-in electric field between S-TiO2 and g-C3N4, facilitating S-scheme charge transfer across the heterointerface and preserving highly reactive electrons and holes with strong reduction and oxidation capabilities, respectively, thereby promoting the generation of \u00b7O2\u2013 and \u00b7OH radicals. As a result, the optimized g-C3N4\/S-doped TiO2 nanotube photocatalyst achieved an NO removal efficiency of 74.6%, higher than those of pristine S-TiO2 (43.4%) and g-C3N4 (53.4%), while also suppressing NO2 intermediate formation compared with previously reported TiO2- and g-C3N4-based heterojunctions. This work provides insight into the synergistic role of band alignment, interfacial built-in electric field, and S-scheme charge transfer in boosting photocatalytic NO removal performance.<\/jats:p>","DOI":"10.1021\/acsami.6c13087","type":"journal-article","created":{"date-parts":[[2026,10,6]],"date-time":"2026-10-06T20:01:36Z","timestamp":1791316896000},"source":"Crossref","is-referenced-by-count":0,"title":["Interfacial Built-In Electric Field-Driven S-Scheme g-C3N4\/S-Doped TiO2 Heterojunction for Boosting Photocatalytic NO Abatement"],"prefix":"10.1021","author":[{"given":"Pho Thi","family":"Le","sequence":"first","affiliation":[{"name":"Vietnam National University Ho Chi Minh City (AMTI) , , Linh Xuan Ward , ,","place":["Ho Chi Minh City, Vietnam, 70000"]},{"name":"University of Science , , ,","place":["Ho Chi Minh City, Cho Quan Ward, Vietnam, 70000"]},{"name":"Vietnam National University Ho Chi Minh City , Linh Xuan Ward , ,","place":["Ho Chi Minh City, Vietnam, 70000"]},{"name":"Thu Dau Mot University , 6 Tran Van On Street, Phu Loi Ward , ,","place":["Ho Chi Minh City, Vietnam, 70000"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thach Khac","family":"Bui","sequence":"additional","affiliation":[{"name":"HUTECH University , , 475A Dien Bien Phu Street, Thanh My Tay Ward , ,","place":["Ho Chi Minh City, Vietnam, 70000"]},{"name":"HUTECH University , , 475A Dien Bien Phu Street, Thanh My Tay Ward , ,","place":["Ho Chi Minh City, Vietnam, 70000"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nhat Quang Minh","family":"Tran","sequence":"additional","affiliation":[{"name":"Vietnam National University Ho Chi Minh City (AMTI) , , Linh Xuan Ward , ,","place":["Ho Chi Minh City, Vietnam, 70000"]},{"name":"Vietnam National University Ho Chi Minh City , Linh Xuan Ward , ,","place":["Ho Chi Minh City, Vietnam, 70000"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tin Chanh Duc","family":"Doan","sequence":"additional","affiliation":[{"name":"Vietnam National University Ho Chi Minh City (AMTI) , , Linh Xuan Ward , ,","place":["Ho Chi Minh City, Vietnam, 70000"]},{"name":"Vietnam National University Ho Chi Minh City , Linh Xuan Ward , ,","place":["Ho Chi Minh City, Vietnam, 70000"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9739-0372","authenticated-orcid":true,"given":"Ali","family":"Anus","sequence":"additional","affiliation":[{"name":"Inha University , , 100 Inha-ro, Michuhol-gu , ,","place":["Incheon, Republic of Korea, 22212"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1447-4536","authenticated-orcid":true,"given":"Sungjin","family":"Park","sequence":"additional","affiliation":[{"name":"Inha University , , 100 Inha-ro, Michuhol-gu , ,","place":["Incheon, Republic of Korea, 22212"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8697-7095","authenticated-orcid":true,"given":"Viet Van","family":"Pham","sequence":"additional","affiliation":[{"name":"HUTECH University , , 475A Dien Bien Phu Street, Thanh My Tay Ward , ,","place":["Ho Chi Minh City, Vietnam, 70000"]},{"name":"HUTECH University , , 475A Dien Bien Phu Street, Thanh My Tay Ward , ,","place":["Ho Chi Minh City, Vietnam, 70000"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,10,7]]},"reference":[{"key":"2026100616013204800_cit1","doi-asserted-by":"publisher","DOI":"10.1126\/sciadv.add2365","article-title":"High urban NOx triggers a substantial chemical downward flux of ozone","volume":"9","author":"Karl","year":"2023","journal-title":"Sci.
