Title
Preparation of ZnS-AgIn5S8/fluoropolymer fiber composites and its photocatalytic H2 evolution from splitting of water under similar sunlight irradiation
Abstract

This paper presented the preparation of ZnS-AgIn5S8/fluoropolymer fiber composites and their performance for H2 evolution from splitting of water under similar sunlight irradiation. The scanning electron microscopy (SEM) images showed that ZnS-AgIn5S8 particles were loaded on the fiber surface by hydrothermal synthesis. The average rate of H2 evolution of ZnS-AgIn5S8 powders slightly decreased, while the average rate of H2 evolution of ZnS-AgIn5S8/fluoropolymer fiber composites increased from the first to the third run. The average rate of H2 evolution using ZnS-AgIn5S8/fluoropolymer fiber composites as catalyst was 2.0 times higher than that of ZnS-AgIn5S8 powders in the third run.

Graphical abstractZnS-AgIn5S8 were successfully loaded onto the surface of the poly(HFBA-co-MAA)/PVDF to prepare ZnS-AgIn5S8/fluoropolymer fiber composites by hydrothermal method. The average rate of H2 evolution using the ZnS-AgIn5S8/fluoropolymer fiber composites as the catalyst achieved 4.8 mL/h.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► ZnS-AgIn5S8/polymer fiber composites have been successfully prepared. ► The composites showed high stability for H2 evolution under Xe lamp irradiation. ► The composites showed higher photocatalytic activity than that of powders. ► The H2 evolution using the ZnS-AgIn5S8 composites as catalyst achieved 4.8 mL/h. ► We report a new composites photocatalyst prepared by hydrothermal method.
