dc.description.abstract | In this study, we utilized calcination and simple impregnation methods to successfully
fabricate bare g-C3N4
(GCN) and x% Ag/g-C3N4
(x% AgGCN) composite photocatalysts with various
weight percentages (x = 1, 3, 5, and 7 wt.%). The synthesized bare and composite photocatalysts were
analyzed to illustrate their phase formation, functional group, morphology, and optical properties
utilizing XRD, FT-IR, UV-Vis DRS, PL, FE-SEM, and the EDS. The photodegradation rate of MO
under solar light irradiation was measured, and the 5% AgGCN composite photocatalyst showed
higher photocatalytic activity (99%), which is very high compared to other bare and composite
photocatalysts. The MO dye degradation rate constant with the 5% AgGCN photocatalyst exhibits
14.83 times better photocatalytic activity compared to the bare GCN catalyst. This photocatalyst
showed good efficiency in the degradation of MO dye and demonstrated cycling stability even in the
5th successive photocatalytic reaction cycle. The higher photocatalytic activity of the 5% AgGCN
composite catalyst for the degradation of MO dye is due to the interaction of Ag with GCN and the
localized surface plasmon resonance (SPR) effect of Ag. The scavenger study results indicate that
O2
•− radicals play a major role in MO dye degradation. A possible charge-transfer mechanism is
proposed to explain the solar-light-driven photocatalyst of GCN. | es |
