Sodium hypophosphite is a promising green source for generating clean elemental hydrogen without pollutants. This study presents the development of an efficient heterogeneous catalyst, Ru/g-CN (Ru/GCN), for hydrogen generation from sodium hypophosphite. The Ru/GCN catalyst demonstrates excellent activity under mild reaction conditions and maintains its effectiveness over multiple cycles without significant loss of activity. This easily separable and recyclable heterogeneous catalyst is straightforward to operate, non-toxic, eco-friendly, and provides a cost-effective alternative to the extensive use of expensive noble metals, which have limited industrial applications. The Ru/GCN catalyst was characterized using various material characterization and spectral methods, including powder X-ray diffraction (PXRD), Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), transmission electron microscopy (TEM), scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS), and X-ray photoelectron spectroscopy (XPS). Hypophosphite, combined with the catalytically active and recyclable Ru/GCN catalyst, forms a system with high potential for industrial-scale hydrogen production, suggesting promising avenues for further research and application.
次磷酸钠是一种很有前景的绿色氢源，可用于生产无污染的纯净元素氢。本研究展示了一种用于从次磷酸钠制氢的高效非均相催化剂Ru/g-CN（Ru/GCN）的开发。Ru/GCN催化剂在温和的反应条件下表现出优异的活性，并且在多个循环中保持其有效性，活性没有明显损失。这种易于分离和可回收的非均相催化剂操作简便、无毒、环保，并且为广泛使用的昂贵贵金属提供了一种经济有效的替代方案，而贵金属的工业应用有限。使用各种材料表征和光谱方法对Ru/GCN催化剂进行了表征，包括粉末X射线衍射（PXRD）、傅里叶变换红外光谱（FTIR）、热重分析（TGA）、透射电子显微镜（TEM）、带有能量色散X射线光谱的扫描电子显微镜（SEM-EDS）和X射线光电子能谱（XPS）。次磷酸盐与具有催化活性且可回收的Ru/GCN催化剂相结合，形成了一个具有工业规模制氢高潜力的体系，为进一步的研究和应用指明了有前景的方向。
