Yb/Ho co-doping and rGO bridging enhance visible-to-NIR-light driven photocatalysis in an S-scheme Heterojunction

Key Points

• The aim is to overcome the challenges of limited light absorption and rapid electron-hole recombination in photocatalytic systems.
• Proposed co-doping of Yb and Ho to enhance light absorption.
• Utilized reduced graphene oxide (rGO) as a bridging material.
• Developed an S-scheme heterojunction for improved charge separation and transfer.
• Significant enhancement in light absorption from visible to near-infrared (NIR) regions.
• Reduced recombination rates of photogenerated electron-hole pairs.
• Improved photocatalytic efficiency compared to traditional methods.
