摘要
本文通过一种简便的制备方法合成了多孔石墨化碳负载的Fe环绕的Ru高度分散的新型催化剂。相比于单一的Ru/C和Fe/C催化剂,这一Ru被Fe隔离的复合催化剂表现出优越的氨分解活性。相关的表征结果表明,Fe不仅能够提高碳的石墨化程度,还能够使得Ru团簇在碳表面更加分散。Fe与Ru金属界面间的协同作用,也是这一催化剂高活性的重要原因之一。
Porous and graphitic carbon supported Fe-around-Ru hybrid catalysts were prepared by a simple method.These isolated Ru clusters showed significantly improved performance for NH_3 decomposition compared to that of single Fe-C and Ru/C catalysts.Characterizations disclosed that Fe species not only played as a graphitization catalysts,but also promoted Ru catalysis,generating a synergistic effects at bimetal interface.
