Self-supporting three-dimensional ZnIn2S4/PVDF–poly(MMA-co-MAA) composite mats with hierarchical nanostructures for high photocatalytic activity

This paper reports the fabrication of self-supporting three-dimensional ZnIn2S4/PVDF–poly(MMA-co-MAA) (ZIS/Polymer) composite mats with hierarchical nanostructures by a simple combination of an electrospinning technique and a hydrothermal process and their high photocatalytic activity. The character...
