摘　　要：低浓度外源乙烯是造成采后果蔬品质劣变的主要原因之一。高效去除外源乙烯已成为解决上述问题的关键。目前,低温催化氧化技术是去除果蔬保鲜场景下低浓度外源乙烯最为安全、高效和经济的方法。本文重点关注了低温乙烯氧化催化剂在果蔬保鲜中的应用情况,分析了低温条件下乙烯催化氧化反应机理,归纳了各贵金属体系催化剂(Au、Ag和Pt基催化剂)的发展情况及趋势;结合催化剂失活问题,汇总了低温乙烯氧化催化剂条件下的失活原因并总结了相应解决策略。最后对低温乙烯催化剂未来发展进行展望,为开发稳定高效的低温乙烯氧化催化剂提供帮助及新思路。Low concentrations of exogenous ethylene are one of the major causes for the quality deterioration of postharvest fruits and vegetables.Efficient removal of exogenous ethylene is key to solving this problem.At present,low-temperature catalytic oxidation technology is the most safe,efficient and economical method for removing low concentrations of exogenous ethylene in fruit and vegetable preservation scenarios.This review article focuses on the application of lowtemperature ethylene oxidation catalysts in fruit and vegetable preservation,analyzes the mechanism of ethylene catalytic oxidation at low temperatures,and summarizes recent developments and future trends of various noble metal catalysts(Au,Ag,and Pt based catalysts).Moreover,based on the issue of catalyst deactivation,the reasons for the deactivation of lowtemperature ethylene oxidation catalysts at low temperatures are discussed and possible solutions to solve this problem are presented.Finally,we give an outlook on the future development of low-temperature ethylene catalysts in order to provide assistance and new ideas for the development of stable and efficient low-temperature ethylene oxidation catalysts.
