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
The interdiction recombination of electron and hole and enhancement visible light absorption is important parameters for boosting efficiency wastewater photodegradation treatment. For this purpose, the various amount of activated carbon (AC)/Chitosan in the form of composite CaFeO-AC/Chitosan were synthesized by solid state method. The structural properties analysis from the X-ray diffraction (XRD) spectra, the existing functional group, and optical properties from the analysis of Fourier transform infrared (FTIR) spectra, and the energy bandgap and photocatalyst performance analysis from the Ultraviolet–visible (UV–Vis) spectra. The band gap energy of the composite CaFeO-AC/Chitosan decreases with increasing the amount of AC/Chitosan in the composite. Photodegradation was carried out using fipronil simulated pesticides wastewater, for 5% AC/Chitosan-CaFeO degraded about 76.95% in 60 min irradiation indicated a high stable photocatalyst, may be due to high crystallite size, distance between two optical phonon, adsorption capacity, and kinetic rate constant. These finding suggest for using chitosan and activated carbon in future for increase the efficiency photocatalyst of fipronil wastewater which were working by suppressing recombination of the charge (electron and hole).
