Description

The photocatalytic degradation technique is one of the suitable ways of dealing with environmental pollutant decontamination. This study demonstrates the ability of graphitic carbon nitride (g-C_3N_4) nanocomposites containing tellurium (Te) and molybdenum disulfide (MoS_2) to photocatalytically destroy organic cationic methylene blue (MB) dye, which is primarily used in the textile industry. Using the alkali treatment approach, layered graphitic carbon nitride (g-C_3N_4) was created. Using MoS_2 and Te, several g-C_3N_4 nanocomposites were created using ultrasonic calcination techniques. After the MoS_2 and Te were immobilized individually, the composites underwent a methodical characterization process utilizing a variety of instruments, including XRD and SEM. Using a 2D layered nano-g-C_3N_4 substrate, the photo-catalytic degradation reaction of MB was observed, and a UV spectrophotometer was used to determine the absorbance of the MB dye. Using 0.2 % MoS_2/g-C_3N_4 and 5 % Te/g-C_3N_4, the photocatalytic degradation efficiency of the MB dye (10, 15, and 20 mg/L) solution was examined. In comparison to other produced nanocomposites, the 5 % Te/g-C_3N_4 composite was shown to have the highest photocatalytic activity in terms of dye degradation ability, and about 100 % of the MB dyes were degraded in less than 60 minutes. As the concentration of MB increased, the dye degradation efficiency of g-C_3N_4 nanocomposites steadily dropped, and the degradation rate of MB was around 1.5 mg/L.
