Bulk and supported nickel phosphides were prepared by thermal treatment of a mechanical mixing of nickel chloride and sodium hypophosphite in a flowing N2. The samples were characterized using thermogravimetric analysis, X-ray diffraction, and inductively coupled plasma. The effect of different aspects on the Ni2P formation was primarily investigated. A rational mechanism was proposed for the selective formation of Ni2P. SiO2-supported Ni2P exhibits excellent hydrodesulfurization (HDS) activity for dibenzothiophene (DBT).
Graphical AbstractA solid-phase reaction of sodium hypophosphite with bulk and supported metal salts (NiCl2 · 6H2O) provides a versatile route to nickel phosphides. SiO2-supported Ni2P exhibits excellent hydrodesulfurization (HDS) activity for dibenzothiophene (DBT).Figure optionsDownload full-size imageDownload as PowerPoint slideResearch Highlights►Bulk and supported nickel phosphides were prepared by thermal treatment of a mechanical mixing of nickel chloride and sodium hypophosphite. ►The operation is therefore simple and the conditions are mild. ►Other metal salts may be used in the method to synthesize corresponding metal phosphides. ►Supported Ni2P exhibits excellent hydrodesulfurization (HDS) activity for dibenzothiophene (DBT).
