摘要：
Fresh fruit not rotting vegetables: Ethylene released from fruits and vegetables accelerates their spoiling even in refrigerators. To oxidatively remove traces of ethylene from a gas mix, supported metal nanoparticles were tested. A Pt catalyst supported on mesoporous silica gave complete conversion of 50 ppm ethylene even at 0 °C. IR experiments suggest the facile oxidation of CO over Pt on the silica supports is the key to the catalytic activity. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
