Encyclopaedia Of Surface , Interface Science & Catalysis : Chemistry & Applications ( 4 Volumes Set )
The world is facing unprecedented challenges in satisfying a rapidly growing demand for energy while reducing negative impacts on the global climate system and the environment. Any solution to these issues will necessarily involve the development of renewable energy sources, together with new strategies for efficient energy utilization and sustainable manufacturing processes. Interface science and catalysis already play an important role in all of these areas, but new catalysts provide improved reactivity and selectivity at dramatically reduced cost need to be developed to enable the required transformations of processes and economies on a global scale. Surface chemistry can be roughly defined as the study of chemical reactions at interfaces. It is closely related to surface engineering, which aims at modifying the chemical composition of a surface by incorporation of selected elements or functional groups that produce various desired effects or improvements in the properties of the surface or interface. Surface chemistry also overlaps with electrochemistry. Surface science is of particular importance to the field of heterogeneous catalysis. The adhesion of gas or liquid molecules to the surface is known as adsorption. This can be due to either chemisorption or by physisorption. These too are included in surface chemistry. The behaviour of a solution based interface is affected by the surface charge, dipoles, energies, and their distribution within the electrical double layer. Several modern methods probe the topmost 1–10 nm of surfaces exposed to vacuum. These include X-ray photoelectron spectroscopy, Auger electron spectroscopy, low-energy electron diffraction, electron energy loss spectroscopy, thermal desorption spectroscopy, ion scattering spectroscopy, secondary ion mass spectrometry, Dual polarization interferometry, and other surface analysis methods included in the list of materials analysis methods. Many of these techniques require vacuum as they rely on the detection of electrons or ions emitted from the surface under study. This book contains a brief review of absorption and catalysis, for practical purposes. It also presents some important information on adsorbents and catalysts.
