Sammanfattning:Title screen
WS2−ZnO nanostructured materials are of great interest inthe area of green energy due to their potential application for hydrogengeneration. In the present work, we report an efficient method to produceWS2−ZnO nanoheterostructures through electrospark erosion of zincgranules in aqueous solutions of hydrogen peroxide, with the simultaneousaddition of nanostructured WS2. WS2−ZnO nanostructures prepared withthis synthesis method were carefully characterized by XRD, TEM, BET,FTIR, UV−vis, and Raman spectroscopy analyses to establish theirchemical compositions and morphology. According to the XRD analysis,the resulting electrospark erosion products represent heterostructurescontaining individual phases of hexagonal tungsten disulfide and zinc oxide.The crystallite sizes varied from 4.3 to 66.7 nm for both phases. Thiscorrelated with the TEM measurements. Cyclic voltammetry (CV) andelectrochemical impedance spectroscopy (EIS) showed that the WS2−ZnOnanostructure decorated electrodes displayed improved conductivity, photocurrent density (by 2.564 mA/cm2), and hydrogen gasevolution under light conditions in contrast to the dark experiments. The investigation confirmed the potential of the WS2−ZnOnanostructures for efficient hydrogen generation for green energy applications
