MgO nanoparticles were prepared by using wet chemical methods such as co-precipitation and hydrothermal method. The synthesized MgO nanoparicles were characterized by X – ray diffraction...

在这项工作中，首先通过同构的 MgO 和 H2O2 反应合成了 MgO2 棒、立方体和花，并将其用作类芬顿氧化剂降解亚甲蓝 (MB)。 通过XRD、SEM和TEM技术对制备的产品的结构和形貌进行表征。 发现合成的 MgO2 保留了 MgO 前体的原始形态。 MgO 前驱体首先与 H2O 相互作用产生水合 MgO 中间体 (MgOH+)，然后被 H2O2 进一步氧化成 MgO2。 花状 MgO 可以在较短的时间内完全转化为 MgO2 相，由于由薄纳米片组装的多孔结构。 此外，MgO 前驱体还可作为 MgO2 原 …

2020年3月1日 · In this literature, magnesium peroxide (MgO 2) nanorods with an average Ddiameter = 166 nm have been successfully synthesized via fast and simple microwave assisted hydrothermal reaction for photocatalysis and antibacterial applications, for the first time.

2019年7月15日 · Herein, highly pure magnesium peroxide (MgO 2) nanoparticles were first synthesized and used instead of H2 O 2 to degrade organic dyes. The structure and morphology of as-prepared products were confirmed by XRD, SEM, TEM and FTIR techniques.

2025年4月1日 · We developed an injectable and in-situ cross-linkable hydrogel (named MOG hydrogel) using MgO 2 nanoparticles and dopamine-conjugated gelatin as main components. MgO 2 was rationally designed as a multifunctional active ingredient to mediate in situ gelation, tumor therapy, and bone repair sequentially.

FE-SEM characterization revealed the presence of MgO with a spherical shape, and the average particle size was confirmed (31.23 nm). As indicated by the anisotropic patterns of MgO, the obtained (Raman) spectrum of MgO shows a strong peak in …

合成的 MgO2 纳米棒通过 XRD、FTIR、TEM、FE-SEM 和 BET 等各种技术进行表征。 研究了 MgO2 纳米棒对甲基橙 (MO) 降解的光催化活性，发现在紫外线照射 50 分钟后，MO 染料已被降解。 已经研究了固体琼脂培养基中 MgO2 纳米棒对 (G + ve) 细菌和 (G -ve) 细菌的抗菌活性。 抗菌活性结果表明，MgO2纳米棒对芽孢杆菌和大肠杆菌具有抑菌功效。 MgO2 纳米棒的抗菌活性随着其在测试介质中浓度的增加而增加。 最后，这些 MgO2 纳米材料价格低廉且易于放大，可用 …

SEM results revealed the synthesized magnesium oxide nanoparticles formed by this cost-effective method are spherically shaped with an average size of < 20 nm.

在此，首先合成了高纯度的过氧化镁（mgo2）纳米颗粒，并用来代替h2o2降解有机染料。 通过XRD，SEM，TEM和FTIR技术证实了所制备产物的结构和形态。 MgO2纳米颗粒的活性氧含量达到26.93 wt％，表明所制备样品的纯度很高。

X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and vibrational sample magnetometer (VSM) are all used to examine the prepared MgO ...
