This work presents the catalytic application of nanostructured nanorod (NR)- and nanowire (NW)–La2O3 catalysts systematically prepared by hydrothermal methods on hydrogen production from NaBH4 solvolysis reactions (hydrolysis/methanolysis). These fresh and spent nanostructured catalysts were characterized by advanced spectroscopic techniques. As a result of the solvolysis reactions of NaBH4 carried out in the presence of nanostructured La2O3 catalysts at 298 K, the methanolysis reaction and the NR-La2O3 catalyst were clearly prominent, with both 4.03 equivalents hydrogen and a hydrogen production rate of 6936 mLH2(gcat·min)−1 in 0.5 min (HPR0.5m). According to the zero-order law kinetic model, the activation energy of NR-La2O3 was found to be 31.07 kJmol−1. Storability tests showed that the NR-La2O3 catalyst had almost the initial activity even after 3 months. As a result, it was understood that the highly capable NR-La2O3 catalyst with its oxygen vacancies and adsorption capabilities could be a pioneer for many catalytic processes, especially NaBH4 methanolysis.
