A novel method for preparing Ni2P/Al2O3(L) catalysts in an N2 atmosphere by decomposition of hypophosphites was proposed, and Ni2P/Al2O3(T) catalyst was synthesized by the temperature programmed reduction method in a H2 atmosphere for comparison. These prepared catalysts were washed with deionized water to remove impurities. The X-ray diffraction, N2-adsorption specific surface area measurements, CO uptake, and X-ray photoelectron spectroscopy were applied to characterize these catalysts. The activities of the Ni2P/Al2O3 catalysts prepared with the two different methods were tested in the dibenzothiophene hydrodesulfurization reaction.

氮气氛下次磷酸盐制备Ni2P/Al2O3加氢脱硫催化剂

提出了一种在N2气氛下通过次磷酸盐分解制备Ni2P/Al2O3(L)催化剂的新方法，并在H2气氛中通过程序升温还原法合成Ni2P/Al2O3(T)催化剂以进行对比。这些制备的催化剂用去离子水洗涤以除去杂质。X 射线衍射、N2 吸附比表面积测量、CO 吸收和 X 射线光电子能谱用于表征这些催化剂。在二苯并噻吩加氢脱硫反应中测试了两种不同方法制备的Ni2P/Al2O3催化剂的活性。
