Enhanced catalytic performance of atomically dispersed Pd on Pr-doped CeO2 nanorod in CO oxidation

Fabrication and catalytic properties of nanorod-shaped (Pt–Pd)/CeO2 composites

“…The catalytic activity of (Pt 0.1 -Pd 0.2 )/CeO 2 also surpasses that of the state-of-the-art CeO 2 -based catalysts reported in the literature, as shown in Table S1. [41][42][43][44][45] † Fig. 9a explores the inuence of O 2 concentration in the feed gas on the catalytic performance of (Pt 0.1 -Pd 0.2 )/CeO 2 .…”

Recent advances in hydrothermal synthesis of facet-controlled CeO2-based nanomaterials

“…CeO 2 shows excellent performance in the process of CO catalytic oxidation due to its unique oxygen storage and release performance and morphology controllability. 76 The generation and elimination of oxygen vacancies in CeO 2 are directly accompanied by the release and storage of oxygen, 77 mainly determined by the type, size, and distribution of surface defect oxygen vacancies. 78 In addition, the change in oxygen vacancy concentration is dependent on particle size.…”

Recent progresses on single-atom catalysts for the removal of air pollutants

“…Heteroatom-doping can adjust the property of supports to improve the activity of SACs ( Zhou X. et al, 2022 ; Meng et al, 2022 ). The CO oxidation activity of Pd/CeO 2 can be enhanced after Pr doping ( Deng et al, 2022 ), which reduces the formation energy of oxygen vacancies around Pd sites, promotes the dissociation of O 2 and reaction rate of CO oxidation. Hydrogen reduction treatment is an effective path to tune the properties of supports.…”

“…CeO 2 is regarded as an outstanding substrate because of its high redox ability and oxygen storage/release properties ( Tan et al, 2020 ; Deng et al, 2022 ). CeO 2 supported PGM single-atoms (such as Pt ( Maurer et al, 2020 ), Au ( Zhao et al, 2019 ), Pd ( Kim et al, 2021 ), and Rh ( Jeong et al, 2020a )) have been widely explored and used for CO oxidation due to their excellent activity, particularly Pt single-atoms loaded on CeO 2 ( Table 1 ).…”
