Over the last decade, significant effort has been devoted to the applications of hierarchically structured porous materials owing to their outstanding properties such as high surface area, excellent accessibility to active sites, and enhanced mass transport and diffusion. The hierarchy of porosity, structural, morphological and component levels in these materials is key for their high performance in all kinds of applications. The introduction of hierarchical porosity into materials has led to a significant improvement in the performance of materials. Herein, recent progress in the applications of hierarchically structured porous materials from energy conversion and storage, catalysis, photocatalysis, adsorption, separation, and sensing to biomedicine is reviewed. Their potential future applications are also highlighted. We particularly dwell on the relationship between hierarchically porous structures and properties, with examples of each type of hierarchically structured porous material according to its chemical composition and physical characteristics. The present review aims to open up a new avenue to guide the readers to quickly obtain in-depth knowledge of applications of hierarchically porous materials and to have a good idea about selecting and designing suitable hierarchically porous materials for a specific application. In addition to focusing on the applications of hierarchically porous materials, this comprehensive review could stimulate researchers to synthesize new advanced hierarchically porous solids.

“…Similarly, a structured vanado-silicate compound has been produced using PS and F127 as hard/soft directing agents to form a macroporous-mesoporous catalyst for cyclooctene epoxidation. 98 Immobilisation of a chiral Co(III)-(PF 6 ) salen complex onto silica possessing 550 nm macropores from PS and 6 nm mesopores from P123 has also be used in chiral epoxidation. 99 A composite SBA-16 3DOM silica support, 100 produced from PMMA and F127 directing agents and an inverse carbon replica, 101 has been used to support chiral cobalt complexes.…”

“…342 Implementation of catalytic materials exhibiting hierarchical and interconnected macromesoporous networks such as CBPM can enhance both internal mass and heat transfer and active site dispersion and accessibility, particularly for such low temperature, liquid phase chemistry as selective transformations of organic molecules. Higher catalytic activity of CBPM systems over their purely mesoporous counterparts has been demonstrated in selective oxidation, [356][357][358] Suzuki coupling, 359 and epoxidation reactions. 404 For example, Parlett et al investigated the effect of support architecture on Pd-catalyzed aerobic selective oxidation of sterically challenging allylic alcohols over hierarchically ordered macro/mesoporous silica systems fabricated using pluronic (P123) and polystyrene (PS) colloids as respective meso-and macropore directing agents ( Figure 25).…”

Nature evolved a variety of hierarchical structures that produce sophisticated functions. Inspired by these natural materials, colloidal self-assembly provides a convenient way to produce structures from simple building blocks with a variety of complex functions beyond those found in nature. In particular, colloid-based porous materials (CBPM) can be made from a wide variety of materials. The internal structure of CBPM also has several key attributes, namely porosity on a sub-micrometer length scale, interconnectivity of these pores, and a controllable degree of order. The combination of structure and composition allow CBPM to attain properties important for modern applications such as photonic inks, colorimetric sensors, self-cleaning surfaces, water purification systems, or batteries. This review summarizes recent developments in the field of CBPM, including principles for their design, fabrication, and applications, with a particular focus on structural features and materials' properties that enable these applications. We begin with a short introduction to the wide variety of patterns that can be generated by colloidal self-assembly and templating processes. We then discuss different applications of such structures, focusing on optics, wetting, sensing, catalysis, and electrodes. Different fields of applications require different properties, yet the modularity of the assembly process of CBPM provides a high degree of tunability and tailorability in composition and structure. We examine the significance of properties such as structure, composition, and degree of order on the materials' functions and use, as well as trends in and future directions for the development of CBPM.
