Abstract Achieving high NO conversion and N 2 selectivity in selective catalytic reduction of by CO (CO‐SCR) a wide operating temperature window, particularly the presence O concentration, remains big challenge. Herein, guided density functional theory (DFT) calculations, catalyst is rationally developed with dual active centers consisting both Co single‐atoms (SAs) CoO x nanoclusters (NCs) co‐anchored on Ce 0.75 Zr 0.25 support (CZO), which show above 99.7% 100% at 250–400 °C under 5 vol% . DFT calculation experimental results confirm strong interaction among SAs, NCs, CZO support. SAs enhance adsorption accompany oxygen vacancies (OVs) formation CZO, while NCs promote to nitrate intermediate breakage NO bond OVs, thus synergistically boosting formation.

The conversion of H2S to high-value-added products is appealing for alleviating environmental pollution and realizing resource utilization. Herein, we report the reduction nitrobenzene aniline using waste as a "hydrogen donor" over catalyst FeCeO2−δ with abundant oxygen vacancies (Ov), especially an asymmetric vacancy (ASOv). electron-rich nature ASOv sites facilitates electron transfer electron-deficient nitro group, promoting adsorption activation Ph–NO2 through elongation cleavage N–O bond. Benefiting from formation sites, resulting achieves impressive 85.6% 81.9% Ph–NH2 selectivity at 1.5 MPa 90 °C, which surpasses that pure CeO2 flower rod morphologies. In situ FT-IR measurements combined density functional theory calculations have elucidated plausible reaction mechanism rate-limiting step in hydrogenation by H2S.

The mechanisms of NO reduction by CO over nitrogen-doped graphene (N-graphene)-supported single-atom Ni catalysts in the presence O2, H2O, CO2, and SO2 have been studied via density functional theory (DFT) modeling. catalyst is represented a single atom bonded to four N atoms on N-graphene. Several alternative reaction pathways, including adsorption site, direct CO, decomposition N2O followed N2, formation active oxygen radical O*, O* were hypothesized energy barrier corresponding each steps was calculated using DFT. most probable pathway found be that adsorbed site decomposes Langmuir-Hinshelwood mechanism form subsequently leaving an (O*) surface, which then reduced CO. large results strong resistance SO2, water vapor. activation N2 larger than those illustrating step rate-controlling step.
