ABSTRACT

Bond-Order Conservation-Morse Potential (BOC-MP) method is used in order to carry
out the calculation. One of the best catalysts for methanol synthesis in catalytic
reduction of CO2 with H2O is Cu/ZnO/Al2O3 whose surface is supported by with some
amount of Pd or Ga. Reduction of CO2 with H2O on Cu will result in methanol
formation; while on Ni will lead to methane formation. In the mechanism of methanol
synthesis from CO2+ H2O on Cu, the formate (HCOO) hydrogenation step is ratedetermining
step and in the mechanism of methane synthesis on Ni, carbon
hydrogenation is rate-determining step. The kinetic of proposed mechanism is
investigated.
