摘要：

Supported Fe-Ni nano-alloy catalysts were prepared by deposition-precipitation with urea. The impact of Fe-Ni composition on the reduction temperature, alloy structure and selective hydrogenation of butadiene performance were investigated by regulating Fe/Ni molar ratio. The results show that Fe-Ni composition can effectively reduce the reduction temperature of mono-metal catalysts Fe and Ni. As Fe molar fraction increases from 0 to 100%, the structure of metal phase gradually changes from face-centered cubic to body-centered cubic. During catalytic hydrogenation, the introduction of Fe has reduced the activity of Ni-based catalysts, but the selectivity to butenes is greatly improved. When Fe/Ni molar ratio is 25/75, the supported Ni3Fe phase of Ni-rich Fe2.-Ni7.-/Ti()2-R catalyst exhibits excellent catalytic activity for butadiene (Tlim% ^ 9 5 °C) and mono-olefin selectivity (> 9 3 %) . © 2024 Science Press.
