Abstract

In this study, a novel hierarchical visible-light responsive photocatalyst was delicately designed and synthesized by anchoring In2S3 flower-like nanostructures on non-woven carbon nanofibers (CNF) for the first time. The nanostructures of these CNF-In2S3 composites were fine tuned, with the aim to achieve the highest photocatalytic hydrogen production activity under visible light. The results indicated that the hierarchical CNF-In2S3-24h photocatalyst exhibited exceptionally high hydrogen evolution rate (ca. 390 μmol h-1), which was around 15 and 12 times higher than that of pure In2S 3 and commercial N-TiO2 nanoparticles, respectively. The prominent photocatalytic hydrogen production activity of the hierarchical CNF-In2S3-24h photocatalyt can be attributed to the excellent properties of enhanced light absorption and efficient charge separation, which are all derived from the special 3D hierarchical nanostructures.
