Abstract: The mechanism of oxidation/reduction of different coalification surface in different electrochemical situations was studied using FTIR and Raman spectragrophy. Analysis of FTIR and Raman spectrum shows that when coal surface was modified with electrochemistry reduction, the functional groups containing oxygen reduce and the hydrophobicity increases.
