摘要: Environmental pollution from human and industrial activities has received much attention as it adversely affects health bio-diversity. In this work we report efficient visible light photocatalytic degradation of phenol using supported zinc oxide (ZnO) nanorods explore the role surface defects in ZnO on activity. were synthesized glass substrates a microwave-assisted hydrothermal process, while defect states controlled by annealing at various temperatures characterized photoluminescence X-ray photoelectron spectroscopy. High performance liquid chromatography (HPLC) was used for evaluation degradation. with high exhibited maximum activity, showing 50% 10 ppm aqueous solution within 2.5 h, rate almost four times higher than that lower defects. The mineralization process during also investigated, showed evolution different byproducts, such benzoquinone, catechol, resorcinol carboxylic acids, stages. results study suggest presence is crucial its which otherwise only active ultraviolet region.
