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 nanofiber with fiber morphology was a key parameter that can effectively overcome the electron–hole fast recombination issue and enhance the activity of photocatalyst under the visible light irradiation. In this work, MoO nanofibers and MoO submicron rods are fabricated through a simple electrospinning method with polyvinyl pyrrolidone/ammonium molybdate as a source to obtain the composite fibers. The composite fibers were treated to various calcination temperatures in order to obtain MoO fibers and MoO rods. The resultant samples were calcined at 350 °C and 550 °C respectively. The diameter ranges from 150 to 250 nm are obtained for lower temperature 350 °C and after the calcination of MoO nanofibers at 550 °C the rods of submicron sizes were formed. Further to study the optical absorption and photocatalyst properties, UV–Vis spectrophotometer was used for the analysis and the band gap energy for the prepared sample from Tauc plot was found to be 3.135 eV. The synthesized MoO rods (i.e.) annealed MoO nanofibers at 550 °C exhibited strong photocatalytic degradation of methylene orange up to 94% in the presence of sunlight without using any oxidizing agents. Graphic Abstract: The photocatalytic degradation of 94% was recorded for annealed MoO nanofibers in presence of sun light without using any oxidizing agents. [Figure not available: see fulltext.]
