本文介绍了一种结构化的铝阳极氧化铝微反应器的发展，表现出高催化活性的无水氨分解为氮气和氢气在中等温度下。修改，如调整的微反应器的几何特征，阳极氧化的催化剂载体的表面积的增强，钌前体的选择，和催化剂促进剂的应用程序的调整，每个都示出影响反应器的性能，以不同程度。该反应器在600°C下将99%的氨转化为相当于60W的氢气。这些数目足以值得认真考虑用于实际应用中，特别是在以氢为燃料的移动的装置中，其中单片结构是有利的。
This paper describes the development of a structured aluminum-anodized alumina microreactor that exhibits high catalytic activity for the decomposition of anhydrous ammonia to nitrogen and hydrogen at moderate temperatures. Modifications such as adjustments to the geometry of the microreactor features, surface area enhancement of the anodized catalyst support, choice of Ru precursor, and application of a catalyst promoter are each shown to affect the reactor performance to varying degrees. The reactor converts 99% of ammonia at 600°C into the equivalent of 60W of hydrogen. These numbers are sufficient for to merit serious consideration for use in practical applications, particularly in mobile devices fueled by hydrogen where monolithic structures are advantageous.
