In this paper, CuO hollow microspheres with different shell thickness and porosity have been synthesized using carbonaceous saccharide microspheres as templates according to a modified literature method. These CuO hollow microspheres were characterized and their catalytic properties in the hydrolytic dehydrogenation of ammonia borane (NH₃BH₃, AB) were examined. A kinetic study indicated that a maximum hydrogen generation rate of 294 mL H₂ min⁻¹ (g catalyst)⁻¹ can be achieved at 45 ± 0.2 °C in the present system, which is comparable with that for other reported Cu based catalysts.

氧化铜空心球：氨硼烷的水解脱氢合成及催化应用

本文采用改进的文献方法，以碳糖微球为模板，合成了壳厚度和孔隙率不同的CuO空心微球。对这些CuO空心微球进行了表征，并研究了它们在氨硼烷（NH ₃ BH ₃，AB）水解脱氢中的催化性能。动力学研究表明，在本系统中，在45±0.2°C的条件下，可以实现294 mL H ₂ min ^-1（g催化剂）^-1的最大氢生成速率，这与其他报道的基于Cu的催化剂相当。
