Supraparticles, particles composed of individual nanoparticles, have attractive properties, but their applicability in real-world applications is often restricted by comparably small dimensions. Suprabeads, which supraparticles are fixed to a larger support bead with the help binder, been proposed address this challenge. These suprabeads retain unique functionalities both nanoparticles and while offering millimeter-sized dimensions for facilitated handling. Here, we investigate role binder formation functionalization suprabeads. First, focus on thermal, mechanical, chemical stabilities as function composition. Our results show that binders containing organic groups offer room-temperature curability, thermal stability resulting limited mechanical depends flexibility binder. Inorganic drastically increase temperature inherently more brittle. Second, demonstrate wetting supraparticle layer enables us tailor resultant suprabead functionality. While low degree embedding provides accessible supraparticles, induces tunable protection from environment. To highlight versatility concept, ideal material can be identified specific application, such ammonia indication or propane dehydrogenation.

Hierarchical porous zeolite particles featuring multiscale pore architectures have gained significant attention due to their enhanced mass transfer properties and superior adsorption capabilities. This study reports the first successful synthesis of hierarchical zeolites with integrated micropores, mesopores, macropores using a template-assisted spray process, addressing limitations conventional in adsorbing large organic molecules such as toluene. By employing poly(methyl methacrylate) (PMMA) (about 350 nm size) template, we achieved precise control over macropore formation, providing new level flexibility tailoring architectures. The effect PMMA/zeolite ratio on resulting macroporous structures toluene performance was systematically investigated. results revealed that exhibited significantly rate compared samples synthesized without PMMA template. improvement is attributed optimized structure, which facilitates efficient transfer. Importantly, this addresses critical gap literature by demonstrating integration into through an environmentally friendly implications for applications volatile compound removal. advancement design could enable more practical solutions industrial air purification environmental remediation.
