•PdS/ZnS NPs are synthesized in-situ and incorporated in PVAc NFs.•The immobilization strategy did not affect the photocatalytic activity of NPs.•The mat can be reused and reveal the same photocatalytic efficiency. Effective PdS/ZnS NPs doped PVAc hybrid electrospun nanofiber mat is introduced as an efficient and reusable photocatalyst. The NPs were synthesized in situ by addition of (NH4)2S to PVAc/ZnAc/PdAc solution. Fabrication of good morphology nanofibers containing PdS/ZnS NPs was achieved by simple, effective, low cost and high yield technology; electrospinning of PVAc/PdS/ZnS colloid. Besides the effective photocatalytic activity, the introduced immobilization strategy of NPs is considered an acceptable methodology to solve the problems of secondary pollution of nanostructural photocatalyst. Overall, the introduced mat can be used as low cost, efficient, and reusable healthily safe photocatalyst to overcome the aforementioned problem.
