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
In this work, the heterogeneous photocatalyst (SiO 2 /Fe 3 O 4 /Ag 2 WO 4 ) that is composed of active nanomaterials precipitated onto mesoporous nanosilica was synthesized using multistep methods. The nanosilica was synthesized using the Stöber method. 10% Wt. of Fe 3 O 4 and Ag 2 WO 4 NPs were precipitated on the surface of nanosilica to produce supported SiO 2 /Fe 3 O 4 /Ag 2 WO 4 magnetic nanoparticles (MNPs). Different techniques were used to characterize the synthesized supported MNPs, including UV-DRS, XRD, VSM, BET, BJH, and FE-SEM. The photocatalytic degradation activity of synthesized supported MNPs was conducted through a batch reactor towards methylene blue dye (M.B) under visible light irradiation (40 W LED and 55 W Xenon lamps). The experimental results showed a high degradation efficiency (approximately 100%) related to SiO 2 /Fe 3 O 4 /Ag 2 WO 4 after 45 min of irradiation time. The SiO 2 /Fe 3 O 4 /Ag 2 WO 4 revealed high adsorption activity, where 60% of its removal efficiency was during the first 60 min of adsorption in the dark. The kinetics studies revealed that the photocatalytic activity of SiO 2 /Fe 3 O 4 /Ag 2 WO 4 was nearly 4.2 and 3.9 times higher than pure Ag 2 WO 4 and SiO 2 /Fe 3 O 4, respectively. The significantly improved photocatalytic activity of the SiO 2 /Fe 3 O 4 /Ag 2 WO 4 MNPs was attributed to their higher stability and specific surface area, in addition to a synergistic outcome between Ag 2 WO 4 and SiO 2 /Fe 3 O 4 that leads to efficient electron–hole pairs separation. The effects of several parameters were also examined for supported MNPs, including catalyst dose, initial concentration of M.B, pH, and H 2 O 2 addition. The reusability and recyclability study revealed that the synthesized SiO 2 /Fe 3 O 4 /Ag 2 WO 4 are highly stable and can be used with high feasibility for removal of different organic dyes from wastewater.
