1945年,依·凯·柴伏斯基在顺磁盐上发现了共振现象,即称顺磁共振。从本质上讲,这种现象是由未成对电子的自转磁矩所引起的,所以又称为电子自转共振(Electron Spin Resonance,简称ESR)。近四十年来,这一技术在物理、化学、生物、矿物等各个领域都有广泛的应用。同样在催化剂开发以及催化机理的探讨方面也得到了显著的效果。本文将简要介绍ESR在多相催化中的应用。纵观目前工业上所用的催化剂,基本上是由过渡金属元素所组成。它们具有共同的特点是,在催化反
In 1945, according to Kay Kay Fu Volkswagen found in the paramagnetic salt resonance phenomenon, called paramagnetic resonance. In essence, this phenomenon is caused by the unmag- ratized magnetic moment of rotation of an unpaired electron, so it is also called Electron Spin Resonance (ESR). In the past forty years, this technology has a wide range of applications in various fields such as physics, chemistry, biology and minerals. Also in the catalyst development and discussion of the catalytic mechanism has also been a significant effect. This article will briefly introduce the application of ESR in heterogeneous catalysis. Looking at the current catalyst used in industry, is basically composed of transition metal elements. They share the common feature of being catalyzed
