摘要

废染料是水污染的主要来源，是一个严重的环境问题。本研究的目的是合成5-20%的ZnO: Fe双层薄膜，并研究该薄膜对罗丹明B的降解。在薄膜x射线衍射图中可以看到具有纤锌矿六方结构的ZnO相的形成。在ZnO薄膜中加入Fe后，ZnO薄膜的能带隙(3.11 ~ 3.09 eV)、透射光谱和晶格应变均略有减小。随着Fe浓度的增加，ZnO薄膜的亲水性和光催化性能明显下降，接触角从51.4下降到70.71，分解效率从61.46%下降到50.35%。随着Fe浓度的升高，双层ZnO层的光学特性降低。

PHOTOCATALYTIC DEGRADATION OF RHODAMINE B UNDER UV USING DOUBLE-LAYER ZnO: Fe THIN FILM

Waste dyes are a major source of water pollution, which is a critical environmental issue. The purpose of this study is to synthesize double-layer ZnO: Fe 5-20% thin films and investigate the degradation of rhodamine B in these films. The creation of the ZnO phase with the wurtzite hexagonal structure may be seen in the thin film X-ray diffraction pattern. Only marginally lessened energy bandgap (3.11-3.09 eV), optical transmission spectra, and lattice strain was seen after Fe was added to ZnO thin films. With increasing Fe concentration, it was found that the hydrophilicity and photocatalytic characteristics of ZnO thin films considerably decreased, as shown by the contact angle going from 51.4 to 70.71 and the decomposition efficiency going from 61.46% to 50.35%. The double-layer ZnO layer's optical characteristics diminish as the Fe concentration rises.

期刊介绍： RASĀYAN Journal of Chemistry [RJC] signifies a confluence of diverse streams of chemistry to stir up the cerebral powers of its contributors and readers. By introducing the journal by this name, we humbly intent to provide an open platform to all researchers, academicians and readers to showcase their ideas and research findings among the people of their own fraternity and to share their vast repository of knowledge and information. The journal seeks to embody the spirit of enquiry and innovation to augment the richness of existing chemistry literature and theories. We also aim towards making this journal an unparalleled reservoir of information and in process aspire to inculcate and expand the research aptitude.
