Ftis Observation Of Twin Adsorbates Of Co On Rh Electrode In Acid Solution, Wenfeng Lin, Shigang Sun
Journal of Electrochemistry
Because of its great importance both in electrocatalysis and C1 chemistry applications, the adsorption of CO on metallic electrodes such as Pt, Pd, Au, Ag, RhF ̄[1~2], etc. has been extensively studied by in situ infrared spectroscopy Since 1981. In all these studies only three types of CO adsorbates, i. e. , linear (2 090~2 000 cm ̄(-1)), bridgrd (2 000~1 900 cm ̄(-1)) or multi-bonded (1900~1 800 cm ̄(-1)) species, were identified. A different absorbate, twin CO on rhodium ((Rh (CO)2) , does exist on the solid/gas interface of highly dispersed Rh or Rhn clusters[3~4] on supports,this species originating a doublet at 2100 …
