Abstract
A series of Bi2O2CO3/g-C3N4@PAN nanofibers were fabricated to evaluate their activities in photocatalytic hydrogen production. Their phase, microstructure and compositions were confirmed by the XRD, SEM, TEM, elemental mapping and XRS results. Their photophysical and photochemical properties were revealed by the UV–vis DRS and emission spectra, photocurrent response and LSV curves. The activities and stabilities were evaluated by the photocatalytic hydrogen production and cycling experiments under the simulated sunlight irradiation. The results indicate that the formation of heterojunction between Bi2O2CO3 and g-C3N4 benefits to the separation of photo-produced electrons and holes, which leads to the enhancements of activity in photocatalytic hydrogen production process.
