Dynamic processes on solid surfaces enable catalytic reactions to occur efficiently and selectively. By facilitating the breaking and formation of chemical bonds, surfaces act as catalysts, guiding the reactant molecules through a choreographed sequence of steps, leading to the desired end products. Unraveling the intricate mechanisms behind catalysis has inspired the development of novel catalysts with enhanced efficiency and selectivity.

Probing the Surface: Tools of the Trade

The ability to observe and manipulate chemical processes on solid surfaces requires powerful microscopic and spectroscopic tools. Researchers harness techniques like scanning tunneling microscopy (STM),atomic force microscopy (AFM),and X-ray photoelectron spectroscopy (XPS) to investigate the atomic and molecular-scale interactions occurring on surfaces.

STM allows scientists to visualize individual atoms and molecules with unprecedented resolution. This technique involves passing a fine-tipped probe over a surface, detecting variations in electrical current that reveal the topography of the sample.

AFM complements STM by providing a three-dimensional view of the surface, enabling researchers to measure mechanical and adhesive properties of molecules. This technique involves scanning a sharp tip across the sample while measuring the van der Waals forces between the tip and the surface.

XPS enables researchers to probe the chemical composition of surfaces by measuring the energy levels of emitted electrons. By analyzing the binding energies, scientists can deduce the nature of atoms and molecules present on the surface and gain insights into the dynamic processes unfolding.

Breaking Barriers: Insights Into Reaction Pathways

The fundamental understanding of dynamic chemical processes on solid surfaces extends beyond static representations. Scientists employ computational modeling, such as density functional theory (DFT),to simulate reactions on surfaces. By utilizing powerful algorithms, researchers can predict reaction pathways, identify reaction intermediates, and estimate reaction kinetics.

Such simulations have proven instrumental in elucidating the intricacies of catalytic reactions, shedding light on kinetic barriers and the influence of surface morphology on reactivity. With the aid of computational approaches, scientists can design efficient catalysts tailored to specific reactions and explore novel reaction mechanisms.

In this book, the author determines that a surface is itself a new material for chemical reaction, and the reaction of the surface provides additional new materials on that surface. The revelation of that peculiarity is what makes this book different from an ordinary textbook, and this new point of view will help to provide a new impetus when graduate students and researchers consider their results. 
The reaction of surface atoms provides additional new compounds, but these compounds cannot be detached from the surface. Some compounds are passive, but others work as catalysts. One superior feature of the surface is the dynamic cooperation of two or more different functional materials or sites on the same surface. This fact has been well established in the preferential oxidation of CO on platinum supported on a carbon nanotube with Ni-MgO at its terminal end. The Pt and Ni-MgO are perfectly separated, but these two are indispensable for the selective oxidation of CO in H₂, where the H₂O molecule plays a key role. The reader will understand that the complexity of catalysis is due to the complexity of the dynamic processes on the surface.
