In this paper, we propose a simple and feasible method for synthesizing bulk and supported nickel phosphides from oxide precursors. The new approach uses a low hydrogen flow speed and is not affected by the heating rate. The results indicate that Ni2P can be synthesized at 600 degrees C from its oxide precursors with a mole ratio of Ni/P = 2/1. The hydrodesulfurization activity results indicate that the direct-reduction method shows excellent performance in the synthesis of supported catalysts. (c) 2012 Elsevier Inc. All rights reserved.
