NiAlZrW hydrodesulfurization catalysts derived from tungstate intercalated NiAlZr layered double hydroxides

Tungstate intercalated NiAlZr layered double hydroxides (LDHs) are synthesized by ion exchange method and their calcined oxides are used as HDS catalysts. Highly dispersed and amorphous NiWO4 species are formed on the catalysts. The introduction of Zr could facilitate the formation of NiWO4 and improve the reducibility by weakening the interaction between W and Al, leading to superior HDS activity.243
