Presence of water with CO + O2 plummets the catalytic activity because of the change in the electronic nature from predominantly oxide (without water in feed) to a Co3O4 surface covered by a few intermediates. However, at ≥375 K, the Co3O4 surface recovers and regains the oxidation activity, at least partially, even in the presence of water. This is fully supported by the changes observed in the work function of Co3O4 under wet (H2O + CO + O2) conditions compared with dry (CO + O2) conditions. This study focuses on the comparative CO oxidation rate on Co3O4 NR surfaces and highlights the changes in the electronic structure that occur in the catalyst during the CO oxidation reaction.</p>10aCatalyst10aNano Structures10aPower X-Ray Diffraction10aspectra10aWater Vapor1 aJain, Ruchi1 aGnanakumar, Edwin, S.1 aGopinath, Chinnakonda, S.  uhttps://library.ncl.res.in/content/mechanistic-aspects-wet-and-dry-co-oxidation-co3o4-nanorod-surfaces-nap-ups-study
