One-pot synthesis of ternary Ag2CO3/Ag/AgCl photocatalyst in natural geothermal water with enhanced photocatalytic activity under visible light irradiation

- Ag2CO3/Ag/AgCl composite was synthesized in geothermal water by a one-pot method.
- Geothermal water served as the source of chlorine and carbonate.
- Ag2CO3/Ag/AgCl exhibited the enhanced photocatalytic activity and stability.
- The efficient charge carrier separation is attributed to the Z-scheme construction.
