Abstract:
Formic acid derived from biomass is known to be used for hydrogen production over Pd catalysts. We studied effects of preparation variables, structure of the carbon support, surface functional composition on the state of Pd and catalytic properties of the samples in the vapor-phase decomposition of formic acid. In all catalysts derived from Pd acetate, metal particles visible by conventional TEM had similar sizes, but the adsorption capacity towards CO responded strongly to N-doping of the carbon surface. Moreover, a decrease in the CO/Pd values was accompanied by a significant increase in the reaction rate. Taking account of XPS and atomic resolution HAADF/STEM data, the trends observed were assigned to a larger fraction of single electron-deficient Pd atoms in the N-doped samples, which do not adsorb CO, but interact with formic acid giving hydrogen. This was confirmed by extended DFT studies. The obtained results are valuable for the development of Pd catalysts on carbon supports for different processes.
