摘要：

The effect of hydrogen adsorption on the Pd(110) surface structure at room temperature has been studied by scanning tunneling microscopy. Depending on the partial pressure of hydrogen two different reconstructions of Pd(110) have been observed: a (1 x 3) phase at hydrogen pressures in the 10(-9) mbar range and an additional (1 x 2) phase at p(H2) greater than or equal to 5 x 10(-8) mbar. Both reconstructions are found to be of the missing-row type. The evolution of the surface reconstructions has been followed in situ.
