| Summary: | This study revolves around assessing the effectiveness of a ternary heterostructure,TiO2/ZnS/g-C3N4 (1:1:1 w/w mixture), synthesized through a facile hydrothermal process for the simultaneous degradation of both single and mixed
pollutants under visible light. The advanced microscopic and spectroscopic techniques(FESEM, TEM, FTIR, UVDRS, BET) employed confirmed its enhanced photocatalytic performance. The UV–Vis DRS analysis unveiled the synthesized
heterostructure’s superior band gap energy of 2.81 eV compared to pristine TiO2,
leading to enhanced light absorption within the visible spectrum. Under visible
light exposure, the ternary TiO2/
ZnS/g-C3N4 heterostructure exhibited impressive
efficacy, removing approximately 90% of 10 mg/L of Rhodamine B (RhB) within
180 min. Furthermore, its remarkable performance extended to mixed pollutants,
wherein it concurrently achieved substantial degradation of 82.7%, 78.2%, and
62.2% for RhB, methyl orange (MO), and 2-chlorophenol (2CP), respectively, in
a comparable timeframe. Notably, only a marginal reduction from 89.9 to 86.6%
was observed in RhB degradation after four recycling cycles, attesting to the
inherent stability and recycling potential of the ternary structure. The synthesis
and application of the ternary TiO2/
ZnS/g-C3N4 heterostructure highlight its significant
potential for practical wastewater treatment, particularly due to its dual
capability of effectively degrading both single and mixed pollutants. The study’s
findings highlight the promising role of this heterostructure in addressing contemporary
challenges in environmental remediation. |
