Among the various postsynthesis treatments of colloidal nanocrystals that have been developed to date, transformations by cation exchange have recently emerged as an extremely versatile tool that has given access to a wide variety of materials and nanostructures. One notable example in this direction is represented by partial cation exchange, by which preformed nanocrystals can be either transformed to alloy nanocrystals or to various types of nanoheterostructures possessing core/shell, segmented, or striped architectures. In this review, we provide an up to date overview of the complex colloidal nanostructures that could be prepared so far by cation exchange. At the same time, the review gives an account of the fundamental thermodynamic and kinetic parameters governing these types of reactions, as they are currently understood, and outlines the main open issues and possible future developments in the field.

“…Recent advances in ligand-assisted loading methods have fostered a renewed interest in stabilizing the valence state of Pt species (that is, PtO); [13] the regulation of cluster sizes enables the control over their electronic and physical properties. [16] Moreover, knowledge of the effects of cluster size is highly desirable, since it has been shown that clusters smaller than 1 nm in diameter are active in photocatalytic water reduction reaction on CdS nanorods. [17,18] In addition, for other systems (e.g., gold particles on TiO 2 ), the size of the metal particles has been found to have an effect on their photocatalytic activity.…”

“…So far, the literature regarding site-selective deposition has been demonstrated on CdSe, CdS, and CdSe/CdS core/shell nanorods with the deposition of various metals, including Au [3,5,41,45,47], Pt [42,48,49], PtCo [42], PtNi [42], Pd, Ag 2 S [41], Co [50], PdO, and Pd 4 S [51]. Thermal-or photochemical-assisted metal deposition can lead to the formation of different metallic patterns on to the semiconductor surface.…”

This chapter will address the development of colloidal synthesis of hybrid metalsemiconductor nanocrystals and their application in the field of photocatalysis. Despite the plethora of examples of different-shaped metal-semiconductor nanostructures that have been reported, metal-tipped semiconductor nanorods are perhaps the most intensively studied, and their use as a photocatalyst will be the focus of the chapter. First, we will discuss different wet-chemical synthesis techniques to control the synthesis of these metal-semiconductor hybrid structures. Afterward, we will discuss their unique physicochemical properties that are a combination of semiconductor and metal properties. Finally, we will showcase several examples from the literature demonstrating the possible application of these unique hybrid structures in photocatalysis.ductors were found to be good photocatalysis, as shown by Costi et al., where redox-based reactions were enhanced by the fact that photogenerated charges in the semiconductor component could be transferred to the metal tip [3]. Such hybrid nanostructures combine different material components into a single nanoparticle and provide a powerful strategy for modifying the properties of nanoparticles. Colloidal metal-tipped semiconductor hybrid nanomaterials were first realized by Banin's group in 2004, where they demonstrated that gold nanocrystals preferentially nucleate and grow at the tips of CdSe nanorods rather than at the sides of the nanorods (Figure 1) [4,5]. These synthetic techniques opened up new possibilities for designing hybrid structures via epitaxial growth between a noble metal and semiconductors in colloidal solution. This can be seen in Figure 2, where TEM images are shown for a few hybrid structures, including Au-CdSe [6,7], Au-ZnSe [8], Au-Bi 2 S 3 [9], Au-SnS [10], and Au-CZTS [11].
