Key Points

The aim is to create a ternary photocatalyst that efficiently degrades Sudan Red III under visible light using a double Z-scheme charge transfer pathway.
Constructed a ternary heterojunction comprising g-C3N4, BiOI, and Ag2CrO4.
Studied the photocatalytic activity under visible light.
Investigated the charge transfer mechanism and degradation efficiency.
The CBA photocatalyst achieved over 90% degradation of Sudan Red III within 120 minutes (95% CI).
Demonstrated a significant enhancement in photocatalytic efficiency compared to individual components (p<0.01).
Established a successful double Z-scheme mechanism, improving charge separation and utilization.

Implication

Study reports the fabrication of a novel ternary heterojunction photocatalyst, showing effective degradation of Sudan Red III under visible light, indicating its potential for wastewater treatment.

Abstract

This study reports the successful fabrication of a novel ternary heterojunction photocatalyst, denoted as CBA (g-C3N4/BiOI/Ag2CrO4), featuring a double Z-scheme charge transfer pathway aimed at the effective degradation of the...
