Abstract
Novel self-assembled architectures have received significant interest in nanoscience and nanotechnology. A large variety of nanostructures involving optimized sizes, morphologies, and compositions are indeed playing major roles in the development of advanced functional materials for several emerging applications. However, the use of nanoparticles (NPs) as building blocks and their assembly into functional architectures is of special relevance for realistic development and represents a rapidly growing branch of research. (1-4) New features arise naturally during the assembly of these architectures, including the emergence of collective behavior due to the interactions between disparate electronic, magnetic, and chemical phenomena. These assembled architectures offer desirable combinations of high internal reactive surface areas and straightforward molecular transport through broad “highways” leading to their surfaces. Porous nanomaterials can be branched out into three different categories according to their pore size: microporous (pore size <2 nm), mesoporous (2 nm < pore size <50 nm), and macroporous (pore size >50 nm) systems. Abundant morphologies are also obtained in monoliths exhibiting hierarchical structures that combine micro-, meso-, and macropores. Micro- and mesopore provide high surface areas while macrospore guarantees accessibility to the surface. (5, 6) To date, significant efforts have been made to design novel hierarchically porous nanostructures using intelligent approaches, which are of significant importance in achieving high-performance applications. For example, the past two decades have witnessed a remarkable drive for the development of ordered mesoporous silicas (7, 8) and their derived ordered mesoporous carbons, (9, 10) mesoporous metals, (11, 12) mesoporous metals oxide, (13, 14) and even polymer nanostructures, (15) most of them being obtained from nanocasting pathway. Of related interest are hierarchically porous nanostructures, both ordered and disordered, leading to a synergistic effect with advanced properties. (16-18) A typical example is that porous graphene materials have recently attracted vast interests due to their large surface areas, unique porous structures, diversified compositions, and excellent electronic conductivity. These unordinary features allow porous graphene materials to serve as advanced electrode materials in high-performance electrochemical energy storage and conversion devices. (19, 20) Moreover, metal–organic frameworks consisting of ordered networks can be constructed from metal cations coordinated to organic molecules, which have recently emerged as a new class of crystalline porous materials.
