Preparation of Hierarchical Porous Zeolite Particles with Multiscale Pore Architectures through a Template-Assisted Spray Process for Enhanced Toluene Adsorption Rate

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: April 1, 2025

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.

Fabrication of hydrophobic activated carbon via chemical vapor deposition using silane coupling agents for the adsorption of benzene in humid conditions

Journal of Physics Conference Series, Journal Year: 2025, Volume and Issue: 3008(1), P. 012022 - 012022

Published: May 1, 2025

Abstract The competitive adsorption between water molecules and volatile organic compounds (VOCs) significantly reduces the efficiency of activated carbon (AC) for VOCs in humid environments. To enhance selectivity VOC adsorption, AC was hydrophobically modified using silane coupling agents (SCA) as a modifier ammonia curing agent via chemical vapor deposition. hydrophobicity textural properties modified-AC (AC/SCA-x) were characterized SEM-EDS, FT-IR, static contact angle measurements, Brunauer-Emmett-Teller (BET) surface area analysis. Results showed that SCA condense with oxygen-containing functional groups on surface, forming hydrophobic coating enhanced its hydrophobicity. As amount increased, AC/SCA-x improved, while specific pore volume decreased. Dynamic experiments, benzene representative VOC, demonstrated breakthrough time unmodified reduced by 54.8% relative humidity rose from 0% to 90%. In contrast, AC/SCA-0.5 decreased only 22.6% under same conditions, 40.9% longer than AC. After three cycles at 90% humidity, maintained 234 minutes, saturated capacity 20.9% lower initial value, demonstrating excellent regeneration capability durability. This study provides promising approach improving performance high-humidity

Adsorbing and recycling alcohols acids from industrial wastewater is of great significance in treatment; establishing the possible quantitative relationship alcohol-acid adsorption capacity with struct0ures adsorbents exploring key factors determining their performance very important challenging environment science. To solve this difficult problem, C1-5 alcohols, C2-4 acids, Fischer-Tropsch synthesis (FTS) on zeolites similar hydrophobicity pore structures (β MFI), hydrophilicity but different (Y MOR), significant differences (MOR vs. β MFI) was systematically investigated. It found that: (1) For materials structures, increased correlates enhanced capacities for acids. (2) hydrophobicity, a higher content ultramicropores leads to (3) Between structure it that ultimately plays decisive role capacities. The behavior FTS exhibits consistent trend, β-zeolite demonstrating highest (contact angle 105°) greatest wastewater, achieving 103 mg/g. Following five adsorption-desorption cycles, retained without degradation, indicating excellent stability reusability. findings identify critical provide solid foundation design development high-performance adsorption.
