In recent times, cost effective synthesis of semiconductor materials has been a subject of concern for the day to today applications. In this work, novelty has been made on the facile synthesis of metal oxides (TiO and CeO) and nanocomposites (TiO-CeO) through sol-gel and precipitation methods of imparting lemon extract. The synthesized materials behave as the functional catalysts which has been further carried out for the photocatalytic degradation against 2,4-Dichlorophenol (2,4-DCP). The materials are then valued for the structural and optical properties. The lemon extract used in synthesis has played a premier role in upgrading the charge carrier separation, bandgap, and size reduction of the composite system. Further, the CeO supported TiO sample acts as the better visible light catalyst, due to the prevention of aggregation and existence of line dislocation that supported to access the additional electron trap sites.
近年来，具有成本效益的半导体材料合成一直是当今应用关注的焦点。在这项工作中，通过溶胶-凝胶和沉淀法引入柠檬提取物，创新性地合成了金属氧化物（TiO 和 CeO）和纳米复合材料（TiO-CeO）。合成材料表现为功能催化剂，并进一步用于光催化降解 2,4-二氯苯酚（2,4-DCP）。然后对材料的结构和光学性质进行了评估。合成中使用的柠檬提取物在提高载流子分离、带隙和复合体系尺寸减小方面发挥了重要作用。此外，CeO 负载的 TiO 样品作为更好的可见光催化剂，因为它可以防止聚集和存在线位错，从而支持获得额外的电子陷阱位。
