Abstract
Photocatalytic CO2 reduction with perovskite can effectively address both energy and environmental issues. Nevertheless, it remains challenging to prepare photocatalysts with suitable hollow tubular structures in rational. Herein, the La1-xSrxCo1-δFeδO3 nanofiber with a hollow tubular structure was fabricated through an electrospinning method. The hollow nanofiber structure was constructed by doping Sr atoms in the A-site and Fe atoms in the B-site of LaCoO3 perovskite. The characterization of TEM proved that the hollow tubular structural La1-xSrxCo1-δFeδO3 nanofiber exhibited an external diameter of about 95 nm and an internal diameter of about 50 nm. The hollow tubular structural La1-xSrxCo1-δFeδO3 nanofiber showed superior carrier separation ability which could exhibit significant advantages for photocatalytic CO2 reduction. The CH3OH generation rate over the optimized La0.8Sr0.2Co0.7Fe0.3O3 nanofiber could reach 5.25 µmol⋅g−1⋅h−1. This work highlighted an electrospinning strategy to build a hollow tubular structural La1-xSrxCo1-δFeδO3 nanofiber for enhancing photoreduction CO2.
