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
Ruthenium (Ru)- and iridium (Ir)-based nanomaterials have always been regarded as efficient electrocatalysts for oxygen evolution reaction (OER) in acidic electrolytes. Herein, we develop a facile dodecylamine-assisted hydrothermal synthesis for producing carbon-supported IrRu alloy nanoparticles with controllable Ir/Ru ratios and ultrafine sizes towards high-efficiency OER and overall water electrolysis. In this strategy, the dodecylamine that serves as a capping and reducing agent enables the final IrRu alloy nanoparticles to possess average sizes <3 nm and high degree of dispersion on carbon substrate. By combining high OER activity of Ru with high acidic robustness of Ir, the as-prepared IrRu/C nanoparticles at a suitable Ir/Ru ratio of 1/3 show good activity and durability for the OER electrocatalysis and overall water splitting. In specific, the IrRu/C catalyst exhibits the lowest overpotential of 302 mV at the current density of 10 mA cm and the highest mass activity of 120.5 mA mg at 1.532 V for OER in 0.5 M HSO electrolyte. In addition, a two-electrode acidic electrolyzer assembled with IrRu/C at anode and commercial Pt/C at cathode (Pt/C|| IrRu/C) exhibits a low cell voltage of 1.44 V for achieving the current density of 10 mA cm, along with a satisfied 20h durability.
