Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Highly dispersed platinum (Pt) nanoparticles are deposited on CeO nanorods via atomic layer deposition (ALD) to improve the catalytic activity towards the NO-CO reaction. For comparison, CeO nanosphere and CeO nanorod loaded Pt nanoparticle catalysts fabricated by ALD and incipient wetness impregnation (IWI) are studied. The size distribution of Pt nanoparticles of Pt/CeO nanosphere (Pt/CeO-NS) and Pt/CeO nanorod (Pt/CeO-NR) catalysts prepared by ALD is quite narrow and uniform (3.05 ± 0.42 nm for Pt/CeO-NSs, and 3.05 ± 0.38 nm for Pt/CeO-NRs) compared to that of the Pt/CeO-NS catalyst prepared by incipient wetness impregnation. The combination of XPS, H-TPR, XAFS and in situ DRIFTS characterization techniques confirms that the strong interaction between Pt nanoparticles and CeO nanorods leads to the decrease of the CO poisoning effect on Pt and activation of oxygen around the interfaces. As a result, the full conversion of NO takes place at a relatively low temperature of ∼200 °C, revealing that the activity of the ALD prepared Pt/CeO-NR catalyst is greatly enhanced.
