Abstract

Sodium borohydride (NaBH₄), a chemical storage material, is an efficient source for safe and effective hydrogen (H₂) storage. In this paper, NiMoO₄ nanorods-supported Co nanoparticles (Co/NiMoO₄) were successfully synthesized using the impregnation-reduction method, and their characterization was carried out using advanced analytical tools such as inductively coupled plasma-optical emission spectrometry (ICP-OES), powder X-ray diffraction (P-XRD), scanning electron microscopy (SEM), High-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), and N₂-adsorption–desorption. In the hydrolysis of NaBH₄, the Co/NiMoO₄ catalyst achieved an H₂ production rate (HGR) of 8572.97 mLg_cat^–1 min^–1 and a turnover frequency (TOF) of 1544.40 molH₂mol_Co^–1 h^–1. Moreover, the Co/NiMoO₄ catalyst exhibited significant stability, retaining 84.98% of its initial HGR efficiency and achieving a 94.90% conversion of NaBH₄ to H₂ after 5 catalytic cycles.

高效可回收的Co/NiMoO₄硼氢化钠水解制氢催化剂

硼氢化钠（NaBH4）是一种安全有效的储氢材料。本文采用浸渍还原法制备了NiMoO4纳米棒负载的Co纳米颗粒（Co/NiMoO4），并利用电感耦合等离子体发射光谱（ICP-OES）、粉末x射线衍射（P-XRD）、扫描电镜（SEM）、高分辨率透射电镜（HRTEM）、x射线光电子能谱（XPS）、n2吸附-脱附等先进分析工具对其进行了表征。在NaBH4的水解过程中，Co/NiMoO4催化剂的H2产率（HGR）为8572.97 mLgcat-1 min-1，周转频率（TOF）为1544.40 molH2molCo-1 h-1。此外，Co/NiMoO4催化剂表现出显著的稳定性，在5次催化循环后，保持了84.98%的初始HGR效率，NaBH4转化为H2的转化率达到94.90%。
