Nanoparticles of the semiconductor Cu2Zn(1-x)Fe(x)SnS4 with different mole fractions of iron (x(Fe)) were synthesized by the decomposition of molecular precursors in oleylamine. The composition, structure, optical, and magnetic properties of the nanoparticles are reported. The parent (Cu2ZnSnS4) zinc material is usually reported as kesteritic and the corresponding iron phase as stannitic; with different site occupancies and tetragonalities. In the small ca. 8-10 nm particles prepared, the smooth variation in lattice parameters and other measured properties suggest that the phase change, with composition, may be absent. SQUID magnetometry suggests that the iron containing samples are ferromagnetic at 5 K and paramagnetic at 300 K.

“…For example, depending on the crystalline quality of the AlN substrate ZnO deposited films show an epitaxial growth [19,20]. Extensive studies have been reported on ZnS nanostructures doped with different transition metal ions (such as Co, Mn, Ni, Fe) prepared by different techniques [21][22][23][24]. Depending on the type of dopant ion, the doped materials exhibit different luminescent, electronic and magnetic properties.…”

Zinc sulfide (ZnS) and zinc sulfide/lead sulfide (ZnS/PbS) nanorods were grown on glass substrates using a thermal evaporation method. The morphology of the prepared samples has been studied by transmission electron microscopy (TEM), field-emission scanning electron microscopy (FE-SEM) and Scanning Electron Microscopy (SEM). Both differences and similarities in morphology between the samples have been discovered. In the ZnS/PbS sample, ZnS nanorods were formed with diameter less than 50 nm and length between 2000 and 3000 nm. The pure ZnS sample has dense structure and its thickness was about 200 nm. Samples were studied in detail using energy-dispersive X-ray spectroscopy (EDX). The surface chemical compositions of the samples were confirmed by means of X-ray photoelectron spectroscopy (XPS). The determination of the crystal structure using the X-ray diffraction revealed that two phases of ZnS, blende and wurtzite, are present in the sample after adding Pb, while only blende is identified in the pure ZnS sample.

Photocorrosion inhibition of sulphide‐based nanomaterials for energy production through photocatalytic water splitting

Summary To overcome the energy shortage and environmental pollution, sunlight is considered an ideal source to solve these problems. Photocatalyst water splitting for H2 production by using solar energy is a favourable technology to deal with the energy shortage, global warming and environmental pollution. During the last few years, sulphide‐based nanomaterial photocatalysts have attained considerable attention due to their comparatively narrow bandgap energy, show excitation in the visible region, at a wavelength of about 600 nm, and thus demonstrate high photocatalytic activities. But semiconductor photocatalysts are easy to be photocorroded due to sensitivity in visible light. The photocorrosion hinder their photocatalytic performance. In order to overcome photocorrosion effects, some modifications in the photocatalysts' surface are required, for example adjusting the metal sulphide structure, depositing anti‐photocorrosion layers or nanoparticles on the surface of semiconductors, which inhibit the photocorrosion attack and sustain the stability. In this review, we discuss progress in the structure, preparation methods, H2 evolution rate, photocorrosion inhibition and energy and environmental applications of different sulphide‐based nanomaterial photocatalysts.
