摘要：

A nitrogen overlayer (N(a)) was synthesized on Pd(100) by catalytic reduction of NO by CO or H2 in the total pressure range of 10-7-101 Torr at crystal temperatures higher than 500 K. The process of the formation of N(a) was monitored by AES, LEED, HREELS and TDS. N(a) formed a c(2 × 2) superlattice, and desorbed at 600-700 K. N(a) was hydrogenated by gas-phase H2. HREELS revealed the reversible formation of NHx(a) species on the surface. © 1990.
