The chemistry of formate on Cu/ZnO catalysts has been an active area of interest because of the controversy regarding the synergistic effects between Cu and ZnO. Surface formate has been suggested as an intermediate for the CO/CO{sub 2}/H{sub 2} hydrogenation reaction to form methanol on copper-based catalysts. Bowker et al. proposed that formate could be easily formed on the surface of polycrystalline copper metal at 305 K from codosing of CO{sub 2}/H{sub 2}, and the rate-determining step of the CO{sub 2} hydrogenation reaction was the hydrogenation and hydrogenolysis of the formate. Klinger and Rathke observed that formate of alkali metal converted into methanol and methyl formate in the presence of PbO. Methanol was also produced from carbon monoxide and water via in situ generation of formate. Herein, the authors have investigated the hydrogenation of copper formate/ZnO mixture, copper formate and zinc formate, focusing on the synergistic effects between copper and ZnO in the CO{sub 2} hydrogenation to methanol. 13 refs., 1 fig., 1 tab.
