Recent advances in the development of photocatalytic NOx abatement

Abstract This chapter provides a recent aspect of photocatalytic technologies for environmental remediation, in particular, photocatalytic NOx abatement. In detail, a major emphasis is given on discussing the progress and development of photocatalytic NOx abatement. The photo-deNOx could be divided into three significant heads: photo-SCR (selective catalytic reduction), photooxidation, and photodecomposition. In this chapter, extensive attention has been given to the photocatalysts, their photocatalytic performance, and photomechanism. The overall conclusion is drawn with the potential future research direction in the development of photo-deNOx.
