Abstract

Through the use of a microwave, iron ore pellets (IOP)-based Ag₂O nanoparticles were successfully synthesized. They were then characterized by means of a vibrating sample magnetometer (VSM), Brunauer-Emmett-Teller (BET) surface area analysis, energy-dispersive X-ray (EDX) analysis, powder X-ray diffraction (XRD) analysis, EDX elemental mapping, and field emission scanning electron microscopy (FESEM). High quantities of tetrahydrobenzo[a]xanthen derivatives were obtained in a brief amount of time by the newly prepared nanocomposite, known as Ag₂O NP@IOP, in a one-pot, three-component reaction involving different aryl aldehydes, naphthol, and dimedone. There is no appreciable loss of catalytic activity when the catalyst is recycled and utilized several times, and it can be easily retrieved using an external magnet. The reason for functionality of designed hybrid catalyst can be related to textural properties such as desirable specific surface area and significant porosity as well as the structural nature of the Ag₂O NP@IOP catalyst.

铁球团基ag2o纳米颗粒作为绿色介质中合成四氢苯并[α]黄原胶的高效双功能非均相催化剂。

利用微波技术，成功地合成了基于铁矿球团（IOP）的Ag2O纳米颗粒。然后通过振动样品磁强计（VSM）、布鲁诺尔-埃米特-泰勒（BET）表面积分析、能量色散x射线（EDX）分析、粉末x射线衍射（XRD）分析、EDX元素映射和场发射扫描电镜（FESEM）对它们进行了表征。新制备的纳米复合材料Ag2O NP@IOP在一锅三组分反应中，涉及不同的芳基醛、萘酚和二美酮，在很短的时间内获得了大量的四氢苯并[a]黄原胶衍生物。当催化剂被回收和利用几次时，催化活性没有明显的损失，并且可以很容易地使用外部磁铁回收。所设计的杂化催化剂功能性的原因可能与结构性质有关，例如理想的比表面积和显著的孔隙率以及Ag2O NP@IOP催化剂的结构性质。

期刊介绍： Frontiers in Chemistry is a high visiblity and quality journal, publishing rigorously peer-reviewed research across the chemical sciences. Field Chief Editor Steve Suib at the University of Connecticut is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to academics, industry leaders and the public worldwide. Chemistry is a branch of science that is linked to all other main fields of research. The omnipresence of Chemistry is apparent in our everyday lives from the electronic devices that we all use to communicate, to foods we eat, to our health and well-being, to the different forms of energy that we use. While there are many subtopics and specialties of Chemistry, the fundamental link in all these areas is how atoms, ions, and molecules come together and come apart in what some have come to call the “dance of life”. All specialty sections of Frontiers in Chemistry are open-access with the goal of publishing outstanding research publications, review articles, commentaries, and ideas about various aspects of Chemistry. The past forms of publication often have specific subdisciplines, most commonly of analytical, inorganic, organic and physical chemistries, but these days those lines and boxes are quite blurry and the silos of those disciplines appear to be eroding. Chemistry is important to both fundamental and applied areas of research and manufacturing, and indeed the outlines of academic versus industrial research are also often artificial. Collaborative research across all specialty areas of Chemistry is highly encouraged and supported as we move forward. These are exciting times and the field of Chemistry is an important and significant contributor to our collective knowledge.
