摘要: Periodic mesoporous organosilica nanoparticles (PMO SiNPs) were developed for the targeted capture of specific volatile organic compounds (VOCs). The removal kinetics adsorbing VOCs fast and maximum could be achieved within less than 30 min. PMO SiNPs removed >99% at a low sorbent dose (i.e. >0.5 mL analyte per g SiNPs). They also showed good recyclability maintained reasonable efficiencies after five cycles 77% 65% hexanal butyric acid vapors, respectively).
