Abstract In this literature, magnesium peroxide (MgO2) 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. The as synthesized MgO2 nanorods are characterized by various techniques like XRD, FTIR, TEM, FE-SEM and BET. The photocatalytic activity of MgO2 nanorods has been studied for methyl orange (MO) degradation, and it is found that MO dye has been degraded after 50 min of the UV illumination. The antibacterial activity of the MgO2 nano-rods in solid agar media has been studied against (G + ve) bacteria and (G -ve) bacteria. The results of antibacterial activity demonstrated that MgO2 nanorods have bacteriostatic efficacy against Bacillus sp and E. coli bacteria. The antibacterial activity of MgO2 nanorods increases with increasing their concentrations in the tested media. Finally, these MgO2 nanomaterials may be used for different electronic nano-devices, photocatalysis reactors and biological applications thanks to their cheap price and easy scaling up.

用于污染物染料去除和抗菌应用的新型过氧化镁 (MgO2) 纳米棒的合成

摘要 在这篇文献中，首次通过快速简单的微波辅助水热反应成功合成了平均 Ddiameter = 166 nm 的过氧化镁 (MgO2) 纳米棒，用于光催化和抗菌应用。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，可用于不同的电子纳米器件、光催化反应器和生物应用。
