On the basis of the characterization of typical catalysts by activityevaluation,TPR,XRD and TEM,the effects of nickel content and promoterssuch as MgO,La_2O_3,
Bond-Order Conservation-Morse Potential(BOC-MP)approach hasbeen used to study the decomposition of methanol(CH_3OH)onFe(111),Pd(111),Pt(111)and Cu(111)surfaces
