Recently, polyaniline (PANI) has received widespread attention for the free volume, optical transmittance and electrical conductivity. In this study, a chemical vapor deposition method was developed to synthesize the conductive PANI-clay composite catalyzed by Fe(III)-saturated attapulgite (Fe(III)-ATTP). The reaction is initiated by the electron transfer from aniline (ANI) to Fe(III), subsequently generating ANI radical cation. The radical could further polymerize and form PANI in the constrained micropore structure of ATTP. The Raman, Fourier transform infrared and X-ray photoelectron spectra confirmed the formation of PANI on Fe(III)-ATTP surface by comparison with the PANI standard. The newly synthesized Fe(III)-ATTP-PANI composite exhibited superior reactivity as indicated by the efficient dissipation of atrazine in the presence of hydrogen peroxide (H₂O₂), and the degradation rate increased up to almost 150 times compared to Fe(III)-ATTP. The higher reactivity of Fe(III)-ATTP-PANI/H₂O₂ system was attributed to the accelerated electron transfer, the formation of ferrous ions, and the enhanced adsorption of atrazine onto attapulgite. Furthermore, our experimental results demonstrated that Fe(III)-ATTP-PANI showed good stability and it could be reused for several reaction cycles with high reactivity. This new material could act as an environmental-friendly catalyst in Fenton-like reaction system and show promising potential to effectively eliminate many persistent organic contaminants.

最近，聚苯胺（PANI）的自由体积，透光率和电导率已受到广泛关注。在这项研究中，开发了一种化学气相沉积方法来合成由Fe（III）饱和的凹凸棒石（Fe（III）-ATTP）催化的导电PANI-粘土复合材料。通过电子从苯胺（ANI）转移到Fe（III）引发反应，随后生成ANI自由基阳离子。该基团可以进一步在ATTP的受限微孔结构中聚合并形成PANI。拉曼光谱，傅立叶变换红外光谱和X射线光电子能谱证实，与PANI标准相比，PANI在Fe（III）-ATTP表面上形成。₂ O ₂），与Fe（III）-ATTP相比，降解率提高了近150倍。Fe（III）-ATTP-PANI / H ₂ O ₂体系的较高反应性归因于加速的电子转移，亚铁离子的形成以及阿特拉津在凹凸棒石上的吸附增强。此外，我们的实验结果表明，Fe（III）-ATTP-PANI表现出良好的稳定性，可以以高反应性用于多个反应循环。这种新材料可以在类似Fenton的反应系统中充当环保催化剂，并显示出有效消除许多持久性有机污染物的潜力。
