In this approach, the utilization of catalytic materials that possess the capacity to initiate the decomposition of the starting material and the subsequent release of hydrogen is of paramount importance. In this study, nickel\/cobalt-plated copper catalysts (NiCo\/Cu) are presented, comprising from 4 to 90 wt.% of cobalt as catalytic materials for hydrogen generation via sodium borohydride (NaBH4) hydrolysis reaction. The NiCo\/Cu catalysts were synthesized via electroless deposition from glycine-based baths, utilizing Ni2+ and Co2+ ions as metal sources and morpholine borane (MB) as the reducing compound. The catalytic performance in alkaline NaBH4 hydrolysis was found to correlate with the cobalt loading in the coating. The maximum rate of hydrogen production, which was determined to be 14.22 L min\u22121 gcat\u22121, was achieved at 343 K for a catalyst composed of 90 wt.% Co. The reaction proceeded with the activation energy of 52.5 kJ mol\u22121, while the catalyst exhibited high durability, preserving nearly 88% of its initial activity after five successive reaction cycles. The combination of nickel and cobalt, along with their synergistic effect and high efficiency in the borohydride hydrolysis reaction, makes them promising catalysts.<\/jats:p>","DOI":"10.3390\/ma19050852","type":"journal-article","created":{"date-parts":[[2026,2,25]],"date-time":"2026-02-25T12:35:17Z","timestamp":1772022917000},"page":"852","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Reusable NiCo\/Cu Catalysts for Sustainable Hydrogen Generation"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-7320-1053","authenticated-orcid":false,"given":"Gitana","family":"Valeckyt\u0117","sequence":"first","affiliation":[{"name":"Department of Catalysis, Center for Physical Sciences and Technology, Saul\u0117tekio Ave. 3, LT-10257 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9526-6383","authenticated-orcid":false,"given":"Zita","family":"Sukackien\u0117","sequence":"additional","affiliation":[{"name":"Department of Catalysis, Center for Physical Sciences and Technology, Saul\u0117tekio Ave. 3, LT-10257 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5880-0970","authenticated-orcid":false,"given":"Virginija","family":"Kepenien\u0117","sequence":"additional","affiliation":[{"name":"Department of Catalysis, Center for Physical Sciences and Technology, Saul\u0117tekio Ave. 3, LT-10257 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-7868-1876","authenticated-orcid":false,"given":"Raminta","family":"\u0160akickait\u0117","sequence":"additional","affiliation":[{"name":"Department of Catalysis, Center for Physical Sciences and Technology, Saul\u0117tekio Ave. 3, LT-10257 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u016brat\u0117","family":"Vai\u010di\u016bnien\u0117","sequence":"additional","affiliation":[{"name":"Department of Catalysis, Center for Physical Sciences and Technology, Saul\u0117tekio Ave. 3, LT-10257 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7555-4399","authenticated-orcid":false,"given":"Loreta","family":"Tama\u0161auskait\u0117-Tama\u0161i\u016bnait\u0117","sequence":"additional","affiliation":[{"name":"Department of Catalysis, Center for Physical Sciences and Technology, Saul\u0117tekio Ave. 3, LT-10257 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0483-0007","authenticated-orcid":false,"given":"Jolanta","family":"Stupakova","sequence":"additional","affiliation":[{"name":"Department of Physics, Faculcy of Fundamental Sciences, Vilnius Gediminas Technical University, Saul\u0117tekio Ave. 11, LT-10223 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4713-5650","authenticated-orcid":false,"given":"Eugenijus","family":"Norkus","sequence":"additional","affiliation":[{"name":"Department of Catalysis, Center for Physical Sciences and Technology, Saul\u0117tekio Ave. 3, LT-10257 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,25]]},"reference":[{"key":"ref_1","unstructured":"(2025, October 23).
