X-ray photoelectron spectroscopy (XPS) is generally considered an important and key technique for surface characterization. This technique provides a total elemental analysis of any solid surface which is vacuum stable or can be made vacuum stable by cooling. XPS is generally regarded as being the most quantitative, the most readily interpretable, and the most informative technique with regard to chemical composition. Previous researchers have used XPS to characterize the surface of coal and associated components. The major elements such as C and O as well as the trace elements in the surface layer have been successfully determined using XPS. However, so far XPS experimental results have not been related to the hydrophobic character of the coal surface. During this quarter, research efforts have been made to characterize the XPS characteristics of the coal surface in terms of its hydrophobic character.
