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
Coconut shell activated carbon (AC) was successfully functionalized with diaminocyclohexane groups. The functionalized AC was used as a carrier to complex metal ions for preparation of the supported Pd, Pd–B and Pd–Ni–B. Pd or its alloy particles were highly dispersed on the functionalized AC and have a narrow size distribution of 2–5 nm. Amorphous structure of Pd–B and Pd–Ni–B were confirmed by the X-ray diffraction (XRD). X-ray photoelectron spectroscopy (XPS) showed that some of the electrons were transferred from B to Pd, which makes Pd electron-enriched. Hydrogen temperature programmed desorption (H 2 -TPD) tests indicated that desorption peaks of the amorphous alloys shifted to higher temperatures with respect to Pd/C, indicating that hydrogen was more strongly bonded to the amorphous alloys. Their catalytic performances were evaluated in hydrogenation of nitroaromatic compounds. In hydrogenation of p -chloronitrobenzene ( p -CNB), the Pd–Ni–B nanoalloys on the functionalized AC displayed a TOF value of 8316/h, and p -CNB conversion of 98.6% with a p -chloroaniline ( p -CAN) selectivity of 94.6%. The highly active hydrogenation property of the Pd–Ni–B/C was further confirmed in reduction of α-nitronaphthalene. In addition to reduction of –NO 2 groups, partial aromatic rings were also hydrogenated over the Pd–Ni–B/C. The substrate conversion was 99.6% together with a highest TOF value of 88/h.
