英文摘要	Zn- and Na-modulated Fe catalysts were fabricated by a simple coprecipitation/washing method. Zn greatly changed the size of iron species, serving as the structural promoter, while the existence of Na on the surface of the Fe catalyst alters the electronic structure, making the catalyst very active for CO activation. Most importantly, the electronic structure of the catalyst surface suppresses the hydrogenation of double bonds and promotes desorption of products, which renders the catalyst unexpectedly reactive toward alkenes-especially C5+ alkenes (with more than 50% selectivity in hydrocarbons)-while lowering the selectivity for undesired products. This study enriches C-1 chemistry and the design of highly selective new catalysts for high-value chemicals.; Natural Science Foundation of China [21473003, 21222306, 21473229, 91545121]; 973 Project [2013CB933100]; SCI(E); EI; PubMed; ARTICLE; zhangqianwen@gmail.com; wxd@sxicc.ac.cn; dma@pku.edu.cn; 34; 9902-9907; 55
