IRAS Study of Adsorbed Formic Acid on a Chromium Oxide Film Grown on Cr(110)

Abstract

Decomposition of formic acid on O/Cr(110)-c(3×1) was studied by IRAS. Two types of formates were found: monodentate observed at 1727 and 1382 cm^-1 and bidentate at 1567 and 1359 cm^-1. Monodentate was decomposed to H₂ and CO₂ at 442 K, and to CO and H₂O at 574 K. Bidentate was decomposed to H₂ and CO₂ at 608 K.
