| Abstract: | Nickel phosphide (Ni2P) is an emerging catalyst for hydrodesulfurization and other important environment- and energy-related catalytic reactions. To understand its high performance, the surface structure of a Ni2P (0 0 0 1) single crystal surface was investigated using dynamical LEED analysis. The obtained surface structure for Ni2P (0 0 0 1)-1 x 1 is a P-covered Ni3P2 structure (Ni3P_P structure) as opposed to the expected bulk terminated surface structures. This Letter discusses the driving force for the formation of the Ni3P_P surface, which involves the minimization of dangling bonds. |
