Heterogeneous Catalysts for Environmental Purification

Abstract

In this chapter, the basics and applications of heterogeneous catalysts for environmental purification, especially for groundwater purification is described. First, it is introduced that catalysts are deeply involved in our lives and as key materials in supporting modern society by taking some practical applications. Then, basic knowledge of the reaction mechanism over a solid catalyst is outlined to facilitate understanding of the catalytic reaction for groundwater purification. Finally, the catalytic reaction for the purification of groundwater polluted with nitrate is described in detail as an example of how solid catalysts are developed. Later, remaining issues and prospect for practical applications of the catalytic purification of groundwater are given.
