Loading gold on TiO 2 to prepare heterogeneous catalysts and use XRD, SEM-EDS, TEM and Raman to test the structure of the catalysts. The aerobic oxidation of aqueous methanol to produce formic acid was studied using gold catalysts. The results show that Au nanoparticles are highly dispersed on the TiO 2 supporter with 4.4nm average particle sizes. By proper selection of the reaction conditions about temperature, pressure, amount of base and catalysts and time, yield of 51.4% of formic acid could be achieved at moderate temperatures and pressures. The preliminary mechanism of the oxidation pathway was also studied that the dehydrogenation of methanol to produce formaldehyde happened at first and following the continuous oxidation to formic acid. The CO 2 as the major byproductwas produced from the intermediate.
