The harmful effect of ethylene arising from fruits and vegetable renders heavy losses of fresh cut products resulting in environmental waste. Herein, we developed nanocomposites composed of visible light active Pt-loaded monoclinic WO3 nanorods on zeolite/WO3-Pt displaying a synergistic effect of ethylene removal. The hydroxyl radicals caused by WO3-Pt migrate into the micropores of the zeolite matrix. These facilitated both adsorbing and decomposing ethylene during fruit storage without requiring a circulation device. The zeolite/WO3-Pt powders were processed with organic binder free granules using a drum rotary method, and ethylene removal capacity was studied by measuring the ethylene concentration, CO2, and increased humidity in tedlar gas sampling bags. The practical applications were tested by evaluating the color change and degree of surface spoilage in tomatoes stored with and without zeolite/WO3-Pt for more realistic conditions, this test was performed in a refrigerator. |
