“…The impressive adsorption capacity, fast equilibrium rate, and high selectivity were resulted from the well-defined hollow porous morphology, uniform size, and high-density of amidoxime groups. [165] Pu is an artificial element. Its radioisotopes such as 239 Pu and 240 Pu are highly radiotoxic, biotoxic, and long-lived hazards, which are abundantly found in radioactive wastes and spent nuclear fuel and released into the environment by human activities.…”

“…or other solid templates is often essential for the production of porous microspheres. [ 89 , 164 , 165 ] However, to use the emulsion templating method to prepare porous or polyHIPE beads/spheres, a pre‐formed O/W (or W/O) emulsion is required to be dispersed in another oil (or water) phase. The polymerization or solidification of the continuous phase of the initial/primary emulsion results in the formation of emulsion‐templated porous spheres.…”

Emulsion templating is at the forefront of producing a wide array of porous materials that offers interconnected porous structure, easy permeability, homogeneous flow-through, high diffusion rates, convective mass transfer, and direct accessibility to interact with atoms/ions/molecules throughout the exterior and interior of the bulk. These interesting features together with easily available ingredients, facile preparation methods, flexible pore-size tuning protocols, controlled surface modification strategies, good physicochemical and dimensional stability, lightweight, convenient processing and subsequent recovery, superior pollutants remediation/monitoring performance, and decent recyclability underscore the benchmark potential of the emulsion-templated porous materials in large-scale practical environmental applications. To this end, many research breakthroughs in emulsion templating technique witnessed by the recent achievements have been widely unfolded and currently being extensively explored to address many of the environmental challenges. Taking into account the burgeoning progress of the emulsion-templated porous materials in the environmental field, this review article provides a conceptual overview of emulsions and emulsion templating technique, sums up the general procedures to design and fabricate many state-of-the-art emulsion-templated porous materials, and presents a critical overview of their marked momentum in adsorption, separation, disinfection, catalysis/degradation, capture, and sensing of the inorganic, organic and biological contaminants in water and air.

“…In addition to W/O or O/W Pickering templates, air-in-water Pickering emulsion templates are also an efficient approach to prepare hollow porous microspheres. Pan and coworkers used a CO2-inwater template stabilized by SiO2 particles to generate hollow porous microspheres by removing particles after interfacial polymerization63 . These microspheres were used as sorbents for fast and highly selective uranium extraction after modification with polyethylene polyamine.…”

Polymer‐based hybrid materials have attracted great interest in academic research and industry because they can effectively combine the advantages of their different components. Pickering emulsions as designer platforms provide a very efficient and often unappreciated route to prepare polymer‐based hybrids. Their applications cover a broad range, including filter media, ion exchange modules, monolithic polymer supports for catalysis, covalent enzyme immobilization, and even scaffolds for tissue engineering. In this article, we first provide an introduction to the basics and formation of Pickering emulsions and then discuss how these systems can be used to obtain templates for the fabrication of materials with various morphologies, such as microspheres, fibers, films, and porous matrices. We then discuss the uniqueness of Pickering systems for morphology control and the resulting added value to obtain advanced complex and hybrid materials. We then review and summarize recent advances in the preparation approaches (polymerization and solvent evaporation) and physical morphologies (microspheres, fibers, films, and porous matrices). Finally, we offer an outlook for future developments.
