Complex Hollow Bowl‐Like Nanostructures: Synthesis, Application, and Perspective

Abstract Contourable design and synthesis in nanomaterial morphology are among the most attractive fields in material science. Among the various nanomaterials, hollow bowl‐like nanomaterials have shown promising potential and achieved great success in many different domains, such as lithium‐ion batteries, supercapacitors, and electro‐ and photochemical catalysts. The unique physicochemical properties of hollow bowl‐like nanomaterials have attracted enormous interest from scientists worldwide. Here, recent researches into bowl‐like nanomaterials, including: (i) synthesis methods, such as the no‐template, no‐patchy template, and patchy template methods; (ii) applications in lithium/sodium/potassium ion‐based batteries, microwave absorption, water‐splitting reactions, and so on are reviewed; and (iii) the problems and challenges are also discussed.
