Selective formation of acetate intermediate prolongs robust ethylene removal at 0 °C for 15 days
Efficient ethylene (C(2)H(4)) removal below room temperatures, especially near 0 °C, is of great importance to suppress that the vegetables and fruits spoil during cold-chain transportation and storage. However, no catalysts have been developed to fulfill the longer-than-2-h C(2)H(4) removal at thi...

description | Efficient ethylene (C(2)H(4)) removal below room temperatures, especially near 0 °C, is of great importance to suppress that the vegetables and fruits spoil during cold-chain transportation and storage. However, no catalysts have been developed to fulfill the longer-than-2-h C(2)H(4) removal at this low temperature effectively. Here we prepare gold-platinum (Au-Pt) nanoalloy catalysts that show robust C(2)H(4) (of 50 ppm) removal capacity at 0 °C for 15 days (360 h). We find, by virtue of operando Fourier transformed infrared spectroscopy and online temperature-programmed desorption equipped mass spectrometry, that the Au-Pt nanoalloys favor the formation of acetate from selective C(2)H(4) oxidation. And this on-site-formed acetate intermediate would partially cover the catalyst surface at 0 °C, thus exposing active sites to prolong the continuous and effective C(2)H(4) removal. We also demonstrate, by heat treatment, that the performance of the used catalysts will be fully recovered for at least two times. |
