Abstract: ABSTRACT The treatment of contaminated wastewater with organic dyes is an important issue to decrease environmental pollution. In this manner, hot melt Adhesives glue gun stick (HMA) and Fe 2 O 3 ‐In 2 O 3 /HMA nanocomposite sheets were prepared via the solution casting technique and assessed for their ability to degrade the carcinogenic Eosin B dye under UV light irradiation. The HMA and Fe 2 O 3 ‐In 2 O 3 /HMA nanocomposites were characterized by SEM, EDX, FTIR, and XRD techniques. The photodegradation study showed that the HMA and its nanocomposites considerably degraded the Eosin B dye. The HMA degraded 70.6% of the dye while the 10 and 20 wt% Fe 2 O 3 ‐In 2 O 3 /HMA nanocomposites degraded 75.8% and 80.4% within 5 h, respectively. The recovered HMA degraded 57.2% of the dye while the 10 wt% and 20 wt% Fe 2 O 3 ‐In 2 O 3 /HMA nanocomposites degraded 63.95% and 69.55% of the dye within 5 h, respectively. The Hinshelwood formula studied the half‐life, and the results for the t 1/2 value were 2.73 min (HMA), 2.47 min (10 wt%) and 2.16 min (20 wt%) were obtained. The crystallite size of HMA, 10 and 20 wt% Fe 2 O 3 ‐In 2 O 3 /HMA nanocomposites were 27.96, 17.53, and 24.28 nm (Scherrer formula), and 29.53, 18.34, and 25.22 nm (Williamson formula), respectively. Further, the cyclic voltammetry study presented that the Fe 2 O 3 ‐In 2 O 3 /HMA nanocomposites had enhanced conductance compared to HMA.
