Nanotechnology is an emerging field in science that exhibits significant promise in the synthesis of nanomaterials for diverse applications. Traditionally, these nanomaterials were manufactured using hazardous and labor-intensive physical and chemical processes. Nevertheless, in recent years, researchers have developed safer, more scalable, and environmentally friendly methods for green synthesis. The problem addressed in this study is the need for an environmentally friendly and efficient synthesis process for titanium dioxide nanoparticles (TiO NPs) with enhanced properties. The aim of this work is to describe the synthesis of TiO NPs with various plant extracts using a green approach and to evaluate the physicochemical characteristics and potential applications of the resulting nanoparticles. This study focuses on understanding how the integration of plant extracts influences the properties of TiO NPs, particularly in terms of their structural, optical, and functional characteristics. The novelty lies in the use of plant extracts as bio-reductants and capping agents, which not only provides a safer and more sustainable synthesis method but also enhances the functional properties of TiO NPs. This green synthesis approach reduces the use of harmful chemicals, making the process more environmentally friendly and economically viable, with potential applications in photocatalysis, antibacterial, and antioxidant activities. The TiO NPs possess diverse functionalities, including photocatalysis, antibacterial properties, and antioxidant properties. The initial precursor, such as a metal salt, undergoes transformation into the desired nanoparticles through the actions of plants exactly. Bio-reduction and capping processes are carried out by secondary metabolites found in bacteria and plants. The results demonstrated that the plant extract-mediated TiO NPs exhibited enhanced photocatalytic activity, superior antibacterial effects, and higher antioxidant potential compared to chemically synthesized TiO NPs. This highlights the potential of green synthesis methods in producing nanomaterials with improved functional properties for a wide range of applications.
纳米技术是科学领域中一个新兴的领域，在合成用于各种应用的纳米材料方面展现出巨大的潜力。传统上，这些纳米材料是通过危险且劳动密集型的物理和化学过程制造的。然而，近年来，研究人员已经开发出更安全、更具可扩展性且环境友好的绿色合成方法。本研究解决的问题是需要一种环境友好且高效的合成工艺来制备具有增强性能的二氧化钛纳米颗粒（TiO NPs）。这项工作的目的是描述使用绿色方法通过各种植物提取物合成TiO NPs，并评估所得纳米颗粒的物理化学特性和潜在应用。本研究着重于理解植物提取物的整合如何影响TiO NPs的性能，特别是在其结构、光学和功能特性方面。其新颖之处在于使用植物提取物作为生物还原剂和封端剂，这不仅提供了一种更安全、更可持续的合成方法，还增强了TiO NPs的功能特性。这种绿色合成方法减少了有害化学物质的使用，使该过程更环保且经济可行，在光催化、抗菌和抗氧化活性方面具有潜在应用。TiO NPs具有多种功能，包括光催化、抗菌性能和抗氧化性能。初始前体，如金属盐，通过植物的作用精确地转化为所需的纳米颗粒。生物还原和封端过程由细菌和植物中发现的次生代谢产物进行。结果表明，与化学合成的TiO NPs相比，植物提取物介导的TiO NPs表现出增强的光催化活性、优异的抗菌效果和更高的抗氧化潜力。这突出了绿色合成方法在生产具有改进功能特性的纳米材料以用于广泛应用方面的潜力。
