摘　　要：接触起电(contact electrification,CE)或摩擦起电(triboelectrification)是两种材料之间通过物理接触产生电荷的现象.本文将介绍基于接触起电过程中电子转移原理的两个新兴领域——接触起电诱导的界面光谱学(contact electrification induced interface spectroscopy,CEIIS)和接触电致催化学(contact-electro-catalysis,CEC).CEIIS是两种材料在接触起电过程中所产生的特征辐射.这种特征光谱传递了有关界面上能量结构的大量信息,开启了一种与界面接触起电相对应的光谱学.接触电致催化学(CEC)是利用机械振动,在接触起电过程中惰性介质之间产生电子转移,从而直接发生催化反应,而无需使用常规催化剂.这种新的催化原理不仅扩大了催化材料的选择范围,而且开创了一个新的催化领域.Contact electrification(CE)or triboelectrification is a phenomenon in which electrical charges are generated through physical contact between two materials.Here,we will introduce two emerging fields based on the principle of electron transfer in the process of contact electrification-contact electrification induced interface spectroscopy(CEIIS)and contact-electro-catalysis(CEC).CEIIS is the photon emission with atomic characteristics produced by two materials in the process of contact electrification.This characteristic spectrum conveys a wealth of information about the energy structure at the interface,opening a spectroscopy corresponding to interfacial contact electrification.CEC is the use of vibration,in the process of contact electrification electron transfer occurs between the mediators to directly catalyze the reaction without the use of conventional catalysts.This new catalytic principle not only expands the selection range of catalytic materials,but also opens up a new field of catalysis.
