Introduction to Metal Alloy Catalysts and Their Interface Phenomena, Structure, and Properties

This chapter explores the structural characteristics of interface phenomena in metal alloys and multimetallic materials. These alloyed metals exhibit enhanced catalytic activity across a range of technological applications, such as thermal catalysis, electrocatalysis, photocatalysis, and photoelectrocatalysis. This chapter explores the inherent structural properties located at the interfaces of metal alloys, covering important topics related to catalytic activity descriptors such as optical properties for light harvesting, the utilization of photon energy, electronic structure modifications, and electrochemical properties. These properties are examined from the perspective of interface design to enhance performance in practical applications. A thorough understanding of structural dynamics resulting from these metal alloy interfaces, which includes structural aspects such as morphology, size, and composition, offers unique design strategies for creating high-performance multimetallic materials with improved catalytic capabilities for various technological developments. Grasping the approach to designing these metal alloy-based material interfaces with precise parameter control is vital for achieving optimal structural properties and enhancing catalytic performance. This chapter provides the foundation for a fundamental understanding of structural dynamics, which is critical for overall comprehension of the application-oriented chapters in this book’s theme.
