Key Points

The study aims to explore the synthesis of Au/g-C3N4 photocatalysts to improve their efficiency in water purification under visible light.
Developed a simple, scalable deposition technique for Au on g-C3N4
Analyzed the photocatalytic activity of various Au/g-C3N4 catalysts
Investigated the role of gold nanoparticle distribution on catalyst performance
Au/g-C3N4 catalysts exhibited significantly enhanced photocatalytic activity
Optimal catalysts showed a bimodal distribution of small gold nanoparticles
Reactive species involved included O2- and photogenerated holes, with minimal contribution from •OH

Abstract

• The synthesis method for depositing Au is crucial for the photocatalytic activity • Au/g-C 3 N 4 catalysts prepared by a simple, scalable deposition technique are the most active catalysts • Addition of Au enhanced electron-hole separation in the graphitic carbon nitride • The most active catalysts were thought to have a bimodal distribution of small gold nanoparticles • The reactive species were O 2 •- and photogenerated holes, with • OH playing a minor role
