Developing advanced oxygen storage materials that deliver high thermal stability is crucial to meeting increasingly stringent environmental regulations for three-way catalysts (TWCs). The surfactant, trialkylamine (N235, N (CnH2n+1), n = 8–10), was used to prepare the zirconium (Zr)-based ceria–zirconia–neodymia composites with loose morphology for the first time, and the effect of N235 on the properties of the ceria–zirconia–neodymia solid solution composites was investigated systematically. After thermal treatment at 1000 °C for 5 h in air, the obtained material (CZ/N235-1000) presented a high surface area of 31 m2 g−1 and had superior redox properties. As a support material in rhodium (Rh)-only TWCs, the prepared Rh/CZ/N235-f and Rh/CZ/N235-a demonstrated excellent catalytic performances. Particularly, after aging at 1000 °C for 5 h in air, the light off temperature (T50%) of nitrogen oxide and carbon monoxide for Rh/CZ/N235-a were 229 °C and 235 °C, respectively, and were much lower than those (278 °C and 280 °C) of Rh/CZ-a in which the support material was synthesized without N235. Therefore, this work provides a simple and scalable synthesis route for advanced oxygen storage materials.

Abstract A Pt-Rh three-way catalyst (M-DS) supported on CeO2-ZrO2-La2O3-Nd2O3 and its analogous supported catalyst (DS) were developed via a modified double-solvent method and conventional double-solvent method, respectively. The as-prepared catalysts were characterized by N2 adsorption-desorption, X-ray diffraction (XRD), CO-chemisorption, X-ray photoelectron spectroscopy (XPS) and hydrogen temperature-programmed reduction (H2-TPR). The preformed Pt nanoparticles generated using ethanol as a reducing agent on M-DS presented enhanced Pt dispersion regardless of aging treatment as confirmed by XRD and CO-chemisorption measurements. The textural properties and reduction ability of M-DS were maintained to a large extent after aging treatment. This result was consistent with those of the N2 adsorption-desorption and H2-TPR, respectively. Meanwhile, the XPS analysis demonstrated that higher Pt0 species and larger Ce3+ concentration could be obtained for M-DS. In the conversion of a simulated compressed natural gas (CNG) vehicle exhaust, both fresh and aged M-DS showed a significant enhancement in the activity and N2-selectivity. Particularly, the complete conversion temperature (T90) of CH4 over the aged M-DS catalyst was 65 °C lower than that over the aged catalyst by conventional double-solvent method.
