This book provides microscopic insights into chemical properties of
NO on metal surfaces. NO/metal systems have been studied
intensively to understand heterogeneous catalysis to detox exhaust
NOx gas. The identification and componential analysis of various
and mixed chemical species of NO adsorbed onto the surfaces have
been significant challenges faced by conventional experimental
techniques, such as vibrational spectroscopies. The author
investigated "individual" NO molecules on Cu surfaces using
low-temperature scanning tunneling microscopy (STM). STM not only
provides information on the geometric, electronic, and vibrational
properties at the single-molecule level; it is also able to
manipulate molecules on surfaces to induce chemical reaction.
Exploiting those techniques, the author chemically identified
individual NO-related species on the surfaces and discovered new
reaction processes for NO reduction, which provides microscopic
insights into the catalytic mechanisms. The author also visualized
wave functions of electrons in a valence orbital of NO and
demonstrated that the wave functions are modified by the formation
of covalent bonding or hydrogen bonding. This is, namely, "the
visualization of quantum mechanics in real space," which is
certainly worth reading. Furthermore, the book demonstrates that
direct observation of valence orbitals helps to elucidate the
reactivity of molecules adsorbed onto surfaces. This innovative
approach to studying molecular properties will contribute to
further development of STM and its related methods.
