Herein, a facile sodium dodecyl sulfate (SDS)-assisted hydrothermal strategy is employed to synthesize nanostructured NiMoO4 electrocatalysts with tailored morphology and enhanced electrocatalytic activity. Acting as a soft-template and structure-directing agent, SDS regulates the nucleation and growth of NiMoO4, resulting in a porous and interconnected nanostructure with abundant exposed active sites. The optimized NiMoO4-SDS-2 electrode exhibits outstanding OER performance, requiring an overpotential of only 428.5 mV to achieve a current density of 100 mA cm\u22122, together with a Tafel slope of 62.4 mV dec\u22121, demonstrating accelerated reaction kinetics. Electrochemical impedance spectroscopy and double-layer capacitance analyses reveal enhanced charge-transfer capability and a larger electrochemically active surface area, while long-term durability tests confirm excellent operational stability under alkaline conditions. The enhanced catalytic performance is associated with SDS-induced morphology regulation, improved active-site accessibility, and favorable interfacial charge-transfer characteristics. This work demonstrates that surfactant-assisted soft-templating is an effective strategy for engineering high-performance NiMoO4-based electrocatalysts and provides valuable insights into the rational design of advanced transition metal oxide catalysts for efficient and durable alkaline water oxidation.<\/jats:p>","DOI":"10.3390\/molecules31183227","type":"journal-article","created":{"date-parts":[[2026,9,14]],"date-time":"2026-09-14T09:34:01Z","timestamp":1789378441000},"page":"3227","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["SDS-Assisted Morphology Regulation of NiMoO4 for Efficient Alkaline Water Oxidation"],"prefix":"10.3390","volume":"31","author":[{"given":"Mrunal","family":"Bhosale","sequence":"first","affiliation":[{"name":"School of Chemical Engineering, Yeungnam University, Gyeongsan 38541, Gyeongsanbuk-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"software","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"}]},{"given":"Pritam J.","family":"Morankar","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Yeungnam University, Gyeongsan 38541, Gyeongsanbuk-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"methodology","vocabulary":"credit"},{"role":"software","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"given":"Sahil S.","family":"Magdum","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Yeungnam University, Gyeongsan 38541, Gyeongsanbuk-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"formal-analysis","vocabulary":"credit"}]},{"given":"Aditya A.","family":"Patil","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Yeungnam University, Gyeongsan 38541, Gyeongsanbuk-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"formal-analysis","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2026-5287","authenticated-orcid":false,"given":"Chan-Wook","family":"Jeon","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, Yeungnam University, Gyeongsan 38541, Gyeongsanbuk-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2207196","DOI":"10.1002\/smll.202207196","article-title":"Synergistic effect of N-NiMoO4\/Ni heterogeneous interface with oxygen vacancies in N-NiMoO4\/Ni\/CNTs for superior overall water splitting","volume":"19","author":"Li","year":"2023","journal-title":"Small"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"765","DOI":"10.1038\/s41561-022-01043-9","article-title":"Orange hydrogen is the new green","volume":"15","author":"Osselin","year":"2022","journal-title":"Nat.
