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.

Nanoporous metals have garnered significant attention in catalysis due to their unique three-dimensional interconnected network structure and pronounced localized surface plasmon resonance (LSPR) properties. In this study, nanoporous Au–Ag shells with varying pore sizes (8, 10, 12, 18 nm) were synthesized, catalytic efficiencies systematically evaluated. The conversion of p-nitrothiophenol (PNTP) dimercapto-azobenzene (DMAB) was used investigate the influence size on reaction kinetics surface-enhanced Raman scattering (SERS) effects. Experimental results reveal that a 12 nm exhibit relatively high efficiency. Furthermore, tuning enables modulation LSPR near-infrared region. These findings highlight critical role determining photocatalytic performance metallic materials provide valuable insights for design optimization highly efficient photocatalysts.
