Photocatalytic reduction of CO2 into methanol and ethanol over conducting polymers modified Bi2WO6 microspheres under visible light

- Conducting polymers modified Bi2WO6 HHMS (CP/Bi2WO6) was successfully synthesized.
- The introduction of CP decreases the recombination of photogenerated e--h+ pairs.
- The PTh/Bi2WO6 exhibites good stability and recyclability for CO2 photoreduction.
- The possible photocatalytic mechanism was discussed and proposed.
