摘要

成功制备了钕(Nd)或钇(Y)修饰的大块Ni2P催化剂(Nd-Ni2P或Y-Ni2P)，并对其在苯并呋喃加氢脱氧中的催化性能进行了研究。用x射线衍射、N2吸附-解吸、CO吸附和x射线光电子能谱对催化剂进行了表征。Nd或Y的加入，特别是Nd的加入，可以增加催化剂的表面积，促进形成更小、更分散的Ni2P颗粒。Nd-Ni2P催化剂的苯并呋喃加氢脱氧活性最高，为95.3%，无o产物收率为74.6%，分别比Ni2P催化剂提高了25.3%和35.4%。

The effect of neodymium and yttrium on benzofuran hydrodeoxygenation performance over a bulk Ni2P catalyst

Neodymium (Nd)- or yttrium (Y)- modified bulk Ni2P catalysts (Nd-Ni2P or Y-Ni2P) have been successfully prepared and their catalytic performance in benzofuran hydrodeoxygenation have been investigated. The as-prepared catalysts were characterised by X-ray diffraction, N2 adsorption–desorption, CO uptake and X-ray photoelectron spectroscopy. The addition of Nd or Y, especially Nd, can increase the surface area of the catalysts and promote the formation of smaller and more highly dispersed Ni2P particles. The Nd-Ni2P catalyst showed the highest benzofuran hydrodeoxygenation activity of 95.3% and the O-free products yield of 74.6%, which gives an increase of 25.3% and 35.4% when compared with that found for Ni2P.
