Hydrolysis of ammonia borane provides a reliable pathway for hydrogen production, while suitable catalysts are indispensable to make the hydrolysis reaction reach a considerable rate. In the present work, a series of TiO₂-supported RuCo catalysts have been fabricated by coprecipitation and subsequent reduction of Ru³⁺ and Co²⁺ on the surface of TiO₂ nanoparticles. Transmission electron microscopy and elemental mapping have verified the good distribution of metal species in the catalysts. The fabricated catalysts have shown excellent performance for catalyzing ammonia borane hydrolysis, especially in alkaline solutions with 0.5 M NaOH. For Ru₁Co₉/TiO₂ in which Ru/Co molar ratio is 1:9, the active energy of catalyzed ammonia borane hydrolysis is 33.25 kJ/mol, and a turnover frequency based on Ru as high as 1408 mol_H2/(mol_Ru·min) is obtained at 25 °C. Moreover, when different types of TiO₂ substrates are used, anatase TiO₂-supported catalysts show better catalytic activity than their counterparts with rutile TiO₂ as substrate or mixture of anatase and rutile TiO₂ as substrate.

氨硼烷的水解提供了可靠的产氢途径，而必不可少的合适催化剂才能使水解反应达到相当高的速率。在本工作中，通过共沉淀并随后在TiO ₂纳米颗粒表面还原Ru ³⁺和Co ²⁺，制备了一系列TiO ₂负载的RuCo催化剂。透射电子显微镜和元素图谱已经证明了催化剂中金属种类的良好分布。制备的催化剂显示出优异的催化氨硼烷水解的性能，尤其是在含0.5 M NaOH的碱性溶液中。对于Ru ₁ Co ₉ / TiO ₂其中Ru / Co摩尔比为1：9，催化的氨硼烷水解的活性能为33.25 kJ / mol，并且在25时获得的Ru转化频率高达1408 mol _H2 /（mol _Ru ·min） ℃。此外，当使用不同类型的TiO ₂底物时，与以金红石TiO ₂为底物或以锐钛矿和金红石TiO _2的混合物为底物的锐钛矿TiO ₂负载的催化剂相比，它们显示出更好的催化活性。
