dc.descriptionPostharvest deterioration caused by ethylene (C2H4) is a major challenge for global food security, leading to significant losses of perishable products like bananas. In this study, we present the synthesis and optimization of a multicomponent photocatalyst based on montmorillonite (MMT), titanium dioxide (TiO2), and silver (Ag), designed for efficient ethylene remediation. The catalysts were prepared via wet impregnation and characterized using FESEM, EDS, and UV−vis reflectance spectroscopy, which confirmed the successful integration of components and a homogeneous elemental distribution. The bandgap energies were determined to be in the range of 3.02 to 4.10 eV, with MMT-rich samples showing values around 3.12 eV. Through a 23 factorial design, the performance was evaluated under three distinct scenarios: adsorption, artificial UV photocatalysis, and natural sunlight-driven photocatalysis. Sample Amt 09 (1.5% TiO2 and 1% Ag) achieved an ethylene removal of over 92% in the artificial UV photocatalysis scenario. Sample Amt 10 (5% MMT, 1.5% TiO2, and 1% Ag) stood out with high performance across all scenarios, suggesting synergistic effects between adsorption and catalytic degradation. Furthermore, an optimized formulation (5% MMT and 2.73% TiO2) achieved 65% ethylene removal under UV light and 47% under natural sunlight. These findings highlight the potential of MMT/TiO2/Ag composites as sustainable, light-driven solutions for postharvest management, offering a scalable platform to extend the shelf life of fresh produce and reduce global food waste.
