Solar-driven NOEDH offers a promising alternative, yet achieving both high activity and high ethene selectivity over noble metal-free catalysts without external heating remains unresolved. Here, we reported that Ti3+-O acid\u2013base pairs on reduced rutile TiO2 enabled highly efficient full-spectrum solar-driven photothermal NOEDH without any external heating. The optimally reduced TiO2 at 750 \u00b0C delivered an ethene production rate of 392.0 mmol g\u20131 h\u20131, which was 1107 times higher than that of pristine TiO2 without reduction pretreatment. The high activity with a C2H4 selectivity of 94.9% surpassed the thermodynamic equilibrium limit and outperformed previously reported systems. Comprehensive characterizations identified surface Ti3+ sites adjacent to lattice oxygen as Lewis acid\u2013base pairs that enhanced light absorption, promoted charge carrier separation, and directly participated in the C\u2013H bond cleavage. Photogenerated electrons also preferentially accumulated on the coordinatively unsaturated Ti3+-O sites, which weakened ethene adsorption, thereby accelerating product desorption and suppressing deep dehydrogenation and coke formation. The synergy between photogenerated hot carriers and localized photothermal heating lowered the apparent activation energy from 157.6 kJ mol\u20131 in the dark to 75.0 kJ mol\u20131 under illumination. This work establishes surface acid\u2013base pairs on noble metal-free catalyst as a powerful platform for sustainable light-driven alkane upgrading.<\/jats:p>","DOI":"10.1021\/jacs.6c08665","type":"journal-article","created":{"date-parts":[[2026,7,16]],"date-time":"2026-07-16T22:14:41Z","timestamp":1784240081000},"page":"31331-31342","source":"Crossref","is-referenced-by-count":1,"title":["Ti3+-O Acid\u2013Base\nPairs for Efficient\nSolar-Driven Photothermal Nonoxidative Ethane Dehydrogenation"],"prefix":"10.1021","volume":"148","author":[{"given":"Yuwen","family":"Sun","sequence":"first","affiliation":[{"name":"Chinese Academy of Sciences , , ,","place":["Shanghai, China, 201210"]},{"name":"University of Chinese Academy of Sciences , ,","place":["Beijing, China, 100049"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kun","family":"Gong","sequence":"additional","affiliation":[{"name":"Chinese Academy of Sciences , , ,","place":["Shanghai, China, 201210"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tianyu","family":"Li","sequence":"additional","affiliation":[{"name":"ShanghaiTech University , , ,","place":["Shanghai, China, 201210"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunlei","family":"An","sequence":"additional","affiliation":[{"name":"Chinese Academy of Sciences , , ,","place":["Shanghai, China, 201210"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiwen","family":"Sun","sequence":"additional","affiliation":[{"name":"Shanghai Yankuang Energy R&D Co., Ltd. , , ,","place":["Shanghai, China, 201203"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tiejun","family":"Lin","sequence":"additional","affiliation":[{"name":"Chinese Academy of Sciences , , ,","place":["Shanghai, China, 201210"]},{"name":"University of Chinese Academy of Sciences , ,","place":["Beijing, China, 100049"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4167-8630","authenticated-orcid":true,"given":"Liangshu","family":"Zhong","sequence":"additional","affiliation":[{"name":"Chinese Academy of Sciences , , ,","place":["Shanghai, China, 201210"]},{"name":"University of Chinese Academy of Sciences , ,","place":["Beijing, China, 100049"]},{"name":"Chinese Academy of Sciences , , ,","place":["Shanghai, China, 201210"]},{"name":"ShanghaiTech University , , ,","place":["Shanghai, China, 201210"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,7,16]]},"reference":[{"issue":"15","key":"2026073109212996900_cit1","doi-asserted-by":"publisher","first-page":"9970","DOI":"10.1021\/acscatal.1c02676","article-title":"Titanium\nSilicalite-1 Nanosheet-Supported Platinum\nfor Non-oxidative Ethane Dehydrogenation","volume":"11","author":"Pan","year":"2021","journal-title":"ACS\nCatal."},{"issue":"18","key":"2026073109212996900_cit2","doi-asserted-by":"publisher","first-page":"7994","DOI":"10.1039\/D1CS01036K","article-title":"Light Olefin\nSynthesis from a Diversity of Renewable and Fossil Feedstocks: State-of\nThe-art and Outlook","volume":"51","author":"Chernyak","year":"2022","journal-title":"Chem.
