Hypothesis
Can a dual-functional Cu2O/g-C3N4 heterojunction effectively detect and remediate water pollutants?
Conclusion
The Cu2O/g-C3N4-0.2 heterojunction shows high sensitivity and stability for water pollution detection and remediation.
Supporting Evidence
- The Cu2O/g-C3N4-0.2 MPH achieved a 98.3% degradation efficiency for methyl orange under visible light.
- It retained an 84.0% efficiency after four cycles and 93.7% after 216 days.
- The SERS sensor exhibited an enhancement factor of 2.43 × 10^6 for 4-ATP detection.
- The relative standard deviation for SERS intensity was below 15%, indicating high consistency.
Takeaway
This study created a special material that can both find and clean up dirty water, making it very useful for keeping our water safe.
Methodology
The Cu2O/g-C3N4 heterojunctions were synthesized and tested for SERS and photocatalytic performance under visible light.
