The decomposition of HCOOH on Pd surfaces over a potential range of practical relevance to hydrogen production and fuel cell anode operation was probed by combining high-sensitivity in situ surface-enhanced IR spectroscopy with attenuated total reflection and thin-layer flow cell configurations. For the first time, concrete spectral evidence of CO(ad) formation has been obtained, and a new main pathway from HCOOH to CO(ad) involving the reduction of the dehydrogenation product of HCOOH (i.e., CO(2)) is proposed.
通过结合高灵敏度的原位表面增强红外光谱与衰减全反射和薄层流动池配置，研究了在对制氢和燃料电池阳极操作具有实际意义的电势范围内 HCOOH 在 Pd 表面上的分解。首次获得了 CO(ad)形成的具体光谱证据，并提出了一条从 HCOOH 到 CO(ad)的新的主要途径，该途径涉及 HCOOH 的脱氢产物（即 CO2）的还原。
