Metric Options: Counts1 Year3 YearSelecting 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
The effect of the addition of a wide range of rare earth elements (Sc, Y, La, Er and Gd) on the catalytic behavior of Rh/AlO base catalyst in the ethanol steam reforming (ESR) reaction was investigated. Physical-chemical properties of Rh-REO-AlO materials have been evaluated by H chemisorption, XRD, BET, TPR, IR spectroscopy and TPO. It was established that the catalytic behavior of the Rh/AlO base catalyst is widely improved by the promotion with rare earth (RE) elements. It has been shown that the RE elements do not have an important impact on the oxidation state and the dispersion of the metallic centers but greatly alter the acid-base properties of the support. It was demonstrated that the catalytic performances of Rh-REO-Al O catalysts are mainly due to the increase of the support basicity and to the rearrangement of acid sites. The presence of a new type of Lewis acid sites (LAS) of weak strength on Rh-REO-Al O materials leads to decrease the production of coke precursor (CH). Finally, the most basic support leads to the highest hydrogen yield and to the less stable coke. © 2008 American Chemical Society.
