Titration by Oxygen of the Spill-over Hydrogen Adsorbed on Ceria–Zirconia Supported Palladium–Rhodium Catalysts

Determination of dispersion of precious metals on CeO2-containing supports

“…As the preliminary experiment, temperature-programmed reduction (TPR) was carried out to determine the reduction condition. The TPR curves of the CeO 2 or CeO 2 -ZrO 2 supports consisted of lowand high-temperature peaks assigned to reductions of the surface and bulk of the supports, respectively [9][10][11][12][13][14][15][16][17][18]. Results of the TPR of Pt/CeO 2 with various Pt contents are shown in Fig.…”

Fabrication of supported Pd–Ir/Al2O3 bimetallic catalysts for 2‐ethylanthraquinone hydrogenation

“…20,21 Such hybrid materials may offer opportunities for synergistic inter-metallic interactions that lead to improvement in catalytic performance. [22][23][24] Pd-based bimetallic catalysts such as Pd-Au, [25][26][27][28] Pd-Ru, 29,30 and Pd-Rh 31,32 have been extensively studied as hydrogenation catalysts. The combination of Pd with Ir has attracted particular attention.…”

The effect of Nd on the properties of ceria–zirconia solid solution and the catalytic performance of its supported Pd-only three-way catalyst for gasoline engine exhaust reduction

“…The reducibility of supported TWCs is an important factor influencing its catalytic performance and H 2 -TPR is a common technique to investigate the reducibility of samples [47][48][49]. The results of consecutive TPR profiles of the supports and the catalysts are presented in Figs.…”
