Abstract: The synthesis of the ZnO-In2S3/FTO semiconductor thin layer was accomplished, aiming to serve as a photocatalyst for degrading methyl orange dyes. ZnO photocatalyst synthesis on FTO was conducted through the current electrodeposition method using a potentiostat device, while the In2S3 coating on ZnO/FTO employed the spray pyrolysis method. The characterization of the sample was performed using XRD and SEM-EDX. The X-ray diffraction analysis revealed the presence of ZnO and In2S3 in the sample, with average crystal grain sizes of 34.28 nm and 41.24 nm, respectively. SEM characterization depicted the morphology of ZnO crystals resembling nanoflowers, while the pattern of agglomerates was identified as In2S3. The EDX data confirmed the presence of Zn, O, In, and S elements.To assess the photocatalytic activity of ZnO- In2S3/FTO, degradation tests against methyl orange were carried out using photocatalysis and photoelectrocatalysis methods under UV and tungsten ray irradiation. The results indicated a more significant decrease in methyl orange concentration under tungsten rays compared to UV lighting, observed in both photocatalysis and photoelectrocatalysis processes.
