Nanoscale AgI-WO3 binary photocatalyst: Synthesis, brief characterization, and investigation of its photocatalytic activity

A mechanistic study of the photocatalytic activity of AgI–WO3 in an experimentally designed approach toward methylene blue photodegradation

“…After completely drying this solution at 100 °C, it was calcined at 500 °C for 2 h, and powdered to obtain WO 3 NPs. 49,51–53…”

“…After centrifuging the suspension, the solid material was dried for a day. Then, it was thoroughly washed with water and sintered at 250 °C for 5 h. 49,52–54…”

“…The binary AgI/WO 3 catalysts with varied AgI : WO 3 mole ratios were prepared by thoroughly hand-mixing aliquot amounts of each as-synthesized AgI and WO 3 semiconductors (at the expected mole ratio value) in an agate mortar for 20 min. 49…”

“…Comparing the values obtained with that of the corresponding blank MB solution ( A 0 ) gave C / C 0 (corresponding to A / A 0 based on the Beer–Lambert law) or degradation percentage of MB ( D % = ([ A − A 0 / A 0 ]) × 100 = ([ C − C 0 / C 0 ]) × 100). 49…”

“…The first part of the work focused on a brief characterization of the samples and kinetic study of the MB photodegradation. 49…”
