Abstract:
Over the past century the science of surfaces has undergone an enormous progress. The atomic and electronic structure, reactivity, and dynamics of many material surfaces have been uncovered. Several Nobel prizes have marked the great accomplishments of our predecessors, from I. Langmuir in 1932 to G. Ertl in 2007. This progress has been fostered and propelled by the continuous development of powerful techniques that have provided atomic and molecular level details of surfaces, adsorption and desorption phenomena, vibration and electronic spectra, electron diffraction and real space imaging by the Scanning Tunneling Microscope. The nature of many techniques has constrained Surface Science to ultra-high vacuum environments. And yet practical surfaces are surrounded by gases and liquids at ambient conditions of pressure and temperature. Under these conditions the surfaces are covered with dense layers of adsorbed molecules. The last two decades have witnessed the development of many new techniques that can operate under ambient conditions, and that can provide spatial and spectroscopic resolution similar to that of vacuum techniques. This new observation window has revealed previously unknown phenomena arising from the adsorption of molecules that interact weakly with the surface that therefore are present in sufficient concentrations only in equilibrium with the gas phase. At relevant ambient temperatures, room temperature and above, many kinetic processes that are frozen at the low temperatures required in vacuum environments are unlocked. In this lecture I will review the physics and chemistry of surfaces with dense layers of adsorbates and new phenomena that derive from this, including hydrogen dissociation reactions on Pd and Ru, dense layers of CO, CO2 and H2 and their effect on the structure of metal surfaces. Prospects for similar studies of the solid-liquid interface, a new frontier in the field, and their impact in environmental science, electrochemistry and energy storage will also be discussed. Finally I will discuss the potential of ultrafast techniques to study dynamic processes with the hope of determining elusive reaction transitions states.
