Abstract

This study presents an innovative method for the synthesis of zinc oxide (ZnO) and iron-doped zinc oxide (Fe-doped ZnO) nanoparticles (NPs), employing extracts derived from tobacco stems. The environmentally friendly green synthesis process here represents the novelty of production and applications. Various analytical techniques including FT-IR, XRD, EDX, SEM and TEM were used to characterise ZnO and Fe-doped ZnO NPs. The study reveals that 1% Fe-doped ZnO NPs demonstrate markedly improved photocatalytic performance, attributed to a narrower band gap and enhanced charge separation. These NPs effectively promote the photocatalytic degradation of methylene blue, a promising approach for wastewater treatment and pollution control. Furthermore, the investigation of Fe-doped ZnO NPs in solar cells demonstrates their potential to substantially improve solar energy conversion efficiency. This novel approach paves the way for sustainable and eco-friendly advancements in both photocatalysis and photovoltaic technologies.

烟草茎提取物介导的绿色合成fe掺杂ZnO纳米颗粒对提高光催化降解亚甲基蓝和太阳能电池效率的作用

本研究提出了一种利用烟草茎提取物合成氧化锌（ZnO）和铁掺杂氧化锌（fe掺杂氧化锌）纳米颗粒（NPs）的创新方法。这里的绿色环保合成工艺代表了生产和应用的新颖性。采用FT-IR、XRD、EDX、SEM和TEM等分析技术对ZnO和fe掺杂ZnO纳米粒子进行了表征。研究表明，掺铁1%的ZnO纳米粒子具有更窄的带隙和更强的电荷分离，从而显著提高了其光催化性能。这些NPs有效地促进了亚甲基蓝的光催化降解，是一种很有前途的废水处理和污染控制方法。此外，铁掺杂ZnO NPs在太阳能电池中的研究表明，它们具有显著提高太阳能转换效率的潜力。这种新颖的方法为光催化和光伏技术的可持续和环保进步铺平了道路。
