摘要：
The adsorption structure and thermal stability of phenylphosphonic acid (PPOA) on Au and Pt polycrystalline surfaces were investigated as a function of PPOA exposure and surface temperature, by infrared reflection absorption spectroscopy (IR-RAS) and a Kelvin probe (KP). The IR-RAS spectra of PPOA on Au and Pt were found to be similar. PPOA is adsorbed without molecule decomposition at 300 K on both surfaces. The molecularly adsorbed PPOA started to desorb at about 350 K, which is similar to the PPOA evaporation temperature. The surfaces studied were shown to be less active than Al, Ti, and Si surfaces with respect to interaction with phosphonic acid. (C) 2011 The Japan Society of Applied Physics
