Regulation on Ce-Bi2MoO6 Band structure for CO2 photoreduction performance enhancement

Key Points

• The aim is to improve CO2 photoreduction performance by regulating the band structure of Ce-doped Bi2MoO6.
• Developed Ce-doped Bi2MoO6 as a photocatalyst for CO2 reduction.
• Assessed photocatalytic activity under visible light.
• Analyzed electronic properties through band structure evaluation.
• Ce doping enhanced the electron-hole separation efficiency.
• The band gap of Bi2MoO6 decreased, allowing for better visible light absorption.
• The reduction potential of photogenerated electrons increased due to elevated conduction band position.
• The introduction of more oxygen defects provided additional sites for CO2 adsorption and activation.
