摘要：

In this work three types of the surface formate, ionic, monodentate and bidentate species, are identified to be the main products of formic acid adsorption on Cu, CuCl, Cu2O and CuO at room temperature. Combined thermal analysis [differential thermal analysis (DTA), thermogravimetry (TG) and evolved gas analysis (EGA)] and FTIR studies have shown that the decomposition selectivity and activity are highly dependent on the electronic and structural properties of the surface formate. The ionic formate which gives the characteristic infrared bands at 1600 and 1320 cm-1 is found to exist on all the surfaces studied in the lower temperature range (
