Advanced electrochemical synthesis of multicomponent metallic nanorods and nanowires: Fundamentals and applications

Multisegmented Metallic Nanorods: Sub‐10 nm Growth, Nanoscale Manipulation, and Subwavelength Imaging

“…Although the fabrication of MS‐M‐NRs has achieved great success, it remains challenging for construction of a complete library of MS‐M‐NRs. A more detailed overview on the fabrication of MS‐M‐NRs can be found elsewhere …”

Microemulsion-Based One-Step Electrochemical Fabrication of Mesoporous Catalysts

“…The direct synthesis of mesoporous materials requires the use of templates or porogen agents (pore directors) to define the pore. To date, these strategies have been classified as endotemplate (soft-templating approach), exotemplate (hard-templating approach), and template-free approach ( Figure 1) [1][2][3][4][5][6][25][26][27][28][29]. Here, we summarize the principal advantages, disadvantages, and resulting materials of each approach: Figure 1.…”

“…The combination of soft-and hard-templating approaches, also known as multiple-templating strategy, is a powerful tool for the creation of complex and hierarchical porous materials, with different properties and enhanced capability and competitiveness for several applications, being particularly useful in heterogeneous catalysis [1,5,[21][22][23]41,42]. The multi-templating approach can be adopted for two different reasons: (i) for the generation of multiple porosity, i.e., to obtain porous materials with various well-defined porous shapes or sizes; or (ii) for the fabrication of porous materials with a desired shape (e.g., mesoporous nanowires or nanorods synthesized using a hard-template as a shape director and a soft-template as a porogen agent).…”

“…The synthesis and design of mesoporous materials is one of the hottest topics being researched in the fields of materials science and heterogeneous catalysis, as they extend the horizon for developing advanced technology to meet the most relevant global challenges (e.g., energy sources, water decontamination, and others) to people, the planet and, prosperity [1][2][3][4]. According to the definition of the International Union of Pure and Applied Chemistry (IUPAC), mesoporous materials are nanoporous materials, ordered or disordered, with pores of diameters ranging from 2 to 50 nm [5,6]. Their potential to eliminate or at least dramatically curb pollution from industrial, chemical, and biological processes, especially for ordered mesoporous materials, is understood based on the enlarged surface area, large pore volumes, relatively low density, chemical functionalities, and permeability properties, among others [7][8][9].…”

“…These special characteristics, which are more relevant in well-ordered mesoporous materials, have attracted intensive research interest in the development of many new mesoporous solids since the discovery of the first hexagonally ordered MCM-41 (Mobil Composition of Matter No. 41) in 1992 by the Mobil Oil Corporation [1][2][3][4][5][6][7][8][9][10][11]. However, the history of ordered mesoporous materials dates back to 1969, when the synthesis of an ordered mesoporous material was first described in a patent literature.…”
