Tunable synthesis of OH − -doped Bi x O y I z nanoparticles for enhanced visible-light photocatalytic degradation of water pollutants

Key Points

• The aim is to investigate how pH and temperature during synthesis affect the photocatalytic performance of BiOI-based nanoparticles.
• Synthesis of BiOI nanoparticles under varying pH conditions and temperatures
• Assessment of photocatalytic performance on water pollutants
• Formation of Bi p(OH)q(NO3)r for creating heterojunctions
• Higher pH synthesis leads to improved photocatalytic effectiveness
• Synthesis at elevated temperatures enhances the formation of the BiOI heterojunction
• BiOI flowerballs exhibit a superior ability to degrade visible-light pollutants
