The photocatalytic process was carried out in a closed reactor equipped with visible lamps (grow LED 10 watt). To identify crystal structure, morphology and composition of composite WO 3 /TiO 2 /SiO 2 , the characterization performed using Scanning Electron Microscopy-Energy Diffraction-X (SEM-EDX). The results of characterization using SEM-EDX showed that composites have a non-uniform pore morphology. The photocatalytic test showed the optimum material weight at 0.15 gram with percent degradation of Rhodamine B dyes of 85.10%. UR - http://jurnal.kimia.fmipa.unmul.ac.id/index.php/JA/article/view/943
