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
Rationally designed and synthesized non-noble metal-based multifunctional electrocatalysts with outstanding activity and durability for oxygen evolution reaction (OER), hydrogen evolution reaction (HER), and oxygen reduction reaction (ORR) are critical to the commercialization of energy-related devices. Herein, two trifunctional electrocatalysts composed of Ni-NiMO (M = Mn or Fe) supported on N-doped carbon nanotubes (NCNT) were in situ synthesized by pyrolysis of NiMn- and NiFe-based precursors, respectively, under a NH/Ar atmosphere. The hybrids exhibit robust trifunctional catalytic performance for HER, OER and ORR in an alkaline electrolyte. Especially, NCNT/Ni-NiMnO exhibits excellent performance for zinc-air batteries with a high specific capacity of 502 mA h g and a maximum power density of 105 mW cm, comparable to that of the Pt/C-based zinc-air battery. This study provides a feasible strategy for preparing highly efficient trifunctional electrocatalysts by in situ coupling metal/metal spinel oxide composites with high conductivity nanocarbon.
