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.
