2022, Chemical Physics ImpactCitation Excerpt :Depending on the position of the reduction peaks these peaks can be clarified as α (T> 280 °C), β (230 °C < T< 280 °C) and γ (T< 230 °C) ones. The broad reduction peak (α) at 284.7 °C can be attributed to the reduction of oxygen in rGO support [38]. The reduction peak (γ) of the undoped sample of Pt/rGO is appearing at around 209.5 °C, while the reduction peak (γ) of the N-doped Pt/N-rGO sample is located at 198.3 °C, indicating the adsorbed oxygen becomes more active.
Enhanced Catalytic Activity for CO Oxidation by Highly Active Pd Nanoparticles Supported on Reduced Graphene Oxide /Copper Metal Organic Framework
2021, Journal of the Taiwan Institute of Chemical EngineersCitation Excerpt :This enhancement of the catalytic activity in the presence of rGO due to graphene-based materials with functional groups and defects of different nature, play one of the major roles in catalysis, by activating oxygen dissociation and electron transfer between gas molecules and catalysts surface [66,67]. Moreover, plays a vital role in the dispersion of Pd NPs on the catalyst surface, resulting in higher number of Pd active sites compared with the catalyst without rGO [67,68]. We suppose, in this case, adsorbed CO molecules play the role of electron donors, forming positively charged radicals and easily interact with negatively charged oxygen radicals on the Pd-rGO-MOF surface.
Recent advances in catalytic systems in the prism of physicochemical properties to remediate toxic CO pollutants: A state-of-the-art review
2021, ChemosphereCitation Excerpt :Yan et al. performed CO oxidation over a graphene oxide supported cobalt oxide hybrid nanocatalyst (rGO-Co3O4). The rGO-Co3O4 catalyst has a uniform particle size, a large surface area, and a narrow distribution of pore sizes, which results in a maximum CO oxidation activity at 100 °C (2nd entry in Table 7) (Yan et al., 2018). Huan et al. prepared a ceria-promoted cobalt oxide catalyst (CeO2–Co3O4) for CO oxidation.
