Abstract This chapter deals with the basics of surface chemistry such as the difference between interface and surface, the relationship between interface and Chemistry Notes for classChapterSurface Chemistry. Some of the most important chemicals are produced industrially by means of reactions that occur on the surfaces of solid catalysts.
