A reasonable construction of hybrid heterogeneous photocatalysts possessing fast charge separation and transfer visible light utilization ability is great significance for enhancing achieving highly efficient photochemical conversion. In this study, a series ZnS/SnS2 heterojunction were prepared by morphology-controlled strategy, the regulation heterostructure was realized photodegradation methyl violet (MV) under light. The results show that as-prepared consists morphological microparticles exhibits nanoparticle/nanosheet interspersed structure. multi-touch interface constructed heterostructures can significantly shorten carrier transport path greatly promote action local electric field at semiconductor/semiconductor interface. Exposed dual-crystal planes SnS2 coupled with ZnS enrich active sites enhance performance pure material. degradation rate MV over optimal material (ZnS/SnS2-50) exceeds 91.4% within 90 min irradiation, which about 62 times compared pristine ZnS.

Recently, the preparation of smart multifunctional hybrid nanoparticles has captured significant interest in versatile areas, including medicine, environment, and food, due to their enhanced physicochemical properties. The present study focuses on synthesis Fe-doped NiO by coprecipitation method using sources nickel (II) acetate tetrahydrate iron (III) nitrate nonahydrate. prepared are characterized X-ray diffraction, Fourier transform infrared spectroscopy, UV–visible field-emission scanning electron microscopy, transmission photon spectroscopic analysis. XRD results clearly confirm face-centered cubic structure polycrystalline nature synthesized Fe-NiO nanoparticles. Tauc plot analysis revealed that bandgap energy decreased with increasing concentration Fe dopant from 2% 8%. XPS samples exhibited existence elements, Fe, Ni, O, absence any surplus compounds. FE-SEM TEM analyses proved formation nanostructured few spherical mostly unevenly shaped particles. Further, photocatalytic efficiency were identified cationic dye rhodamine B (Rh-B). 8% doped achieved 99% Rh-B degradation within 40 min visible-light irradiation. Hence, exemplified have acted as a noticeable photocatalyst degrade dye.
