| dc.description.abstract | The preparation of WO3-ZnO composites through the solid state reaction has been conducted. The research stages
included mixing WO3 and ZnO solids with the addition of polyvinyl alcohol, drying, sieving and heating. WO3 and
ZnO solids before being composited and WO3-ZnO composites were characterized using X-Ray Diffraction
(XRD), Scanning Electron Microscope (SEM) instrument, and test the surface area using methylene blue
solution. The results of XRD characterization showed that the samples containing WO3 and ZnO also contained
ZnWO4 diffraction peaks. In SEM analysis, it can be observed that the size and shape of the particles was not
homogeneous. WO3-ZnO composite has a surface area of 110.7596 m2/g | en_US |
