“…5 shows the XRD patterns of NH 2 –Al 2 O 3 , Ru/Al 2 O 3 and Ru/NH 2 –Al 2 O 3 . NH 2 –Al 2 O 3 exhibited diffraction peaks at 2 θ = 37.5°, 45.7°, and 66.6°, which were attributed to the (311), (400) and (440) lattice planes of γ-Al 2 O 3 (JCPDS 50-0741), 32 indicating that the crystal structure of Al 2 O 3 had no obvious change after silylation modification. For supported Ru catalysts, Ru/Al 2 O 3 showed characteristic peaks of Ru at 2 θ = 42.2°, 43.4°, and 77.9°, corresponding to the (002), (101), and (103) lattice planes of Ru (0), while no obvious diffraction peaks of Ru were detected in the XRD curve of Ru/NH 2 –Al 2 O 3 , indicating high dispersion of Ru on Ru/NH 2 –Al 2 O 3 .…”

Pt-based alumina catalysts doped with varying niobium contents (i.e., 0, 1.20, 2.84, and 4.73 wt%, denoted as Pt/Nb–Al2O3) were synthesized via stepwise impregnation for catalytic CO oxidation. The effective incorporation of Nb species without altering the fundamental properties of the Al2O3 support was confirmed by the characterization using XRD, Raman, and TEM. Pt metallic particles were uniformly deposited on the niobium-doped alumina (Nb–Al2O3) support. H2-TPR and CO–TPD analyses were performed to reveal the influence of niobium doping on catalyst reduction and CO adsorption properties. The results consistently demonstrate that the doping of niobium affects reducibility and alleviates the competitive adsorption between CO and O2 during the CO reaction. Particularly, when compared to both undoped and excessively doped Pt/Al2O3 catalysts, the catalyst featuring a 2.84 wt% Nb content on Pt1.4/Nb2.8–Al2O3 displayed the most promising catalytic performance, with a turnover frequency of 3.12 s−1 at 180 °C. This superior performance can be attributed to electron transfer at the Pt/NbOx interface.
