The influence of cadmium precursors upon PdS/Zn1-XCXS photocatalysts efficiency in watersplitting reaction
Photocatalysts based on hexagonal cadmium sulfide have been hydrothermally synthesized using crystalline zinc sulfide as sulfide source, and metal nitrates, acetates, chlorides and sulfatesas cadmium sources. The powders have been characterized by X-Ray Diffraction (XRD), UV-VIS Diffuse Reflectance...

| Tartalmi kivonat: | Photocatalysts based on hexagonal cadmium sulfide have been hydrothermally synthesized using crystalline zinc sulfide as sulfide source, and metal nitrates, acetates, chlorides and sulfatesas cadmium sources. The powders have been characterized by X-Ray Diffraction (XRD), UV-VIS Diffuse Reflectance Spectroscopy (DSR)and Energy-Dispersive X-ray Spectroscopy (EDX). Further experiments of photocatalysis in aqueous solution of sulfide and sulfite for hydrogen evolution, were conducted. The samples were irradiated by monochromatic blue light, generated by an LED. From these experiments it was concluded that the presence of sulfate and acetate anions in the system results in more performantphotocatalysts than the presence of nitrate and especially chlorideanions. |
