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
In this study, specific generation of 1 O 2 was achieved by activation of peroxymonosulfate (PMS) using N-doped porous carbon with Fe nanoparticles (NPC-Fe), synthesized by carbonizing MIL-88B(Fe) metal-organic frameworks modified with ionic liquid. Fe(II) in the catalyst was found to react with PMS to form •O2−, and Pyridinic N promoted the conversion of •O2− to 1 O 2. Consequently, the NPC-Fe/PMS reaction system could generate a large amount of 1 O 2 by the synergistic effect of Fe(II) and Pyridinic N. The system demonstrated excellent performance in a wide pH range for the degradation of contaminants represented by antibiotics. Additionally, the catalyst NPC-Fe had good stability and recyclability. This work provides novel insights for generating 1 O 2 by activation of PMS for environmental remediation.
