Facile Green and Hydrothermal Synthesis of ZnO Nanorods using Eucalyptus Extract: Photocatalytic Degradation of Cationic Dye

The present study aimed to use Eucalyptus leaves extract for the green synthesis of ZnO oxide (ZnO) nanorods (NRs) using the hydrothermal method. The X-ray diffraction (XRD) patterns confirmed that the ZnO NRs had a hexagonal crystal structure with high crystal quality. FTIR analysis revealed the presence of functional groups associated to the formation of ZnO NRs. The optical band gap was calculated using the Tauc plot. Scanning electron microscopy (SEM) revealed rod-like morphology of the as-fabricated ZnO, which is further confirmed by the transmission electron microscopy (TEM) analysis. Furthermore, the biosynthesized ZnO NRs were used as photocatalysts for degradation of Rhodamine B (RhB) dye under ultraviolet radiation. Based on these results, ZnO NRs with a concentration of 20 mL of the eucalyptus extract revealed exceptional performance with a photocatalytic degradation rate of 94.77% under UV irradiation for 90 min. According to these results, wastewater can be treated effectively via the designed catalysts using the green and facile synthesis techniques.

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
