摘要
高分子负载金属催化剂由于催化活性好、稳定性高、反应后容易和产物分离、易于从反应体系中分离回收和重复使用等原因,近年来成为了人们的研究热点之一。纤维素是自然界中储量最丰富的天然高分子,其在大多数有机溶剂中稳定,且其比表面积大,结构中含有大量羟基,可参与许多反应。本文以自然界中储量丰富、无毒、可降解、可再生的天然高分子纤维素为载体,按照纤维素负载金属催化剂制备方式的不同,综述了纤维素负载Pd、Ag、Au、Cu等金属催化剂的制备及其在有机反应中的应用。
Most of the polymer-supported metal catalysts have obvious advantages such as high catalytic activity,easy separation and purification of product after reaction and easy recovery and reuse several times without any remarkable loss in catalytic activity.Cellulose is one of the most abundant natural polymer on earth.It is stable in most organic solvents,has high surface area and hydroxyl functional groups that are capable of chelating to metal ions and particles thereby providing required stability.In addition,it is biodegradable,non-toxic and available at low price.In this paper,synthesis of cellulosebased metal catalysts and their applications in organic transformation were summarized.
