The inhibition of ethylene exposure is necessary for preserving the quality of postharvest fruit and vegetables.In this study,we report a rational design of Pd-based MFI composite adsorbents consisting of Pd-ZSM-5 and S-l zeolites with high ethylene adsorption capacity even in the humid environment.The effects of S-l incorporation on the morphology,apparent surface area,Pd nanoparticles distribution,and the hydrophobicity of the MFI composite were investigated in relation to their ethylene adsorption performance in dry and humid environments.Our finding reveals a synergistic effect between the Si-rich layer and Pd nanoparticles on moisture protection and ethylene capture,respectively,leading to an exceptional ethylene adsorption ability of S-1/Pd-ZSM-5 under high relative humidity.Compared with the conventional ZSM-5-supported Pd adsorbent,S-1/Pd-ZSM-5 exhibited a two-fold enhancement in ethylene removal in the presence of moisture(0.195 mmol/g vs.0.416 mmol/g).In particular,the secondary crystallization of S-1 achieved by 72 h of hydrothermal treatment gave an excellent confinement over the Pd-ZSM-5 structure.This novel design of S-1/Pd-ZSM-5 provides the valuable applicability of the composite zeolite for ethylene regulation in postharvest crops in the future.
