This paper presents an alternative method for the preparation of bulk and supported nickel phosphide by the heat treatment of a mixed salt precursor (nickel chloride and sodium hypophosphite) in a static protecting gas atmosphere up to 300 degrees C. After reduction at 500 degrees C. a Ni2P/MCM-41 catalyst exhibits good hydrodesulfurization activity for dibenzothiophene with a turnover frequency at 330 degrees C of 1.1 x 10(-3) s(-1).
