Zinc oxide (ZnO) is a fascinating semiconductor material with many applications such as adsorption, photocatalysis, sensor, and antibacterial activities. By using a poly (vinyl alcohol) (PVA) polymer as a capping agent and metal oxides (iron and manganese) as a couple, the porous PVA-aided Zn/Fe/Mn ternary oxide nanocomposite material (PTMO-NCM) was synthesized. The thermal, optical, crystallinity, chemical bonding, porosity, morphological, charge transfer properties of the synthesized materials were confirmed by DTG/DSC, UV–Vis-DRS, XRD, FT-IR, BET, SEM-EDAX/TEM-HRTEM-SAED, and CV/EIS/amperometric analytical techniques, respectively. The PTMO-NCM showed an enhanced surface area and charge transfer capability, compared to ZnO. Using the XRD pattern and TEM image analysis, the crystalline size of the materials was confirmed to be in the nanometer range. The porosity and superior charge transfer capabilities of the PTMO-NCM were confirmed from the BET, HRTEM (IFFT)/SAED, and CV/EIS analysis. The adsorption kinetics (adsorption reaction/adsorption diffusion) and adsorption isotherm test confirmed the presence of a chemisorption type of adsorbate/methylene blue dye-adsorbent/PTMO-NCM interaction. The photocatalytic performance was tested on the Congo red and Acid Orange-8 dyes. The superior ascorbic acid sensing capability of the material was understood from CV and amperometric analysis. The noble antibacterial activities of the material were also confirmed on both gram-negative and gram-positive bacteria.

PVA辅助的Zn-Fe-Mn偶联氧化物纳米复合材料的多功能应用

氧化锌(ZnO)是一种引人入胜的半导体材料,具有许多应用,例如吸附,光催化,传感器和抗菌活性。通过使用聚乙烯醇(PVA)聚合物作为封端剂和金属氧化物(铁和锰)作为对,合成了多孔PVA辅助的Zn / Fe / Mn三元氧化物纳米复合材料(PTMO-NCM)。通过DTG / DSC,UV-Vis-DRS,XRD,FT-IR,BET,SEM-EDAX / TEM-HRTEM-证实了合成材料的热,光学,结晶度,化学键合,孔隙率,形态,电荷转移性质。 SAED和CV / EIS /安培分析技术。与ZnO相比,PTMO-NCM的表面积和电荷转移能力增强。使用XRD图案和TEM图像分析,确认材料的晶体尺寸在纳米范围内。通过BET,HRTEM(IFFT)/ SAED和CV / EIS分析证实了PTMO-NCM的孔隙率和优异的电荷转移能力。吸附动力学(吸附反应/吸附扩散)和吸附等温线测试证实了化学吸附类型的被吸附物/亚甲基蓝染料-吸附剂/ PTMO-NCM相互作用的存在。在刚果红和酸性橙8染料上测试了光催化性能。通过CV和安培分析可以了解该材料优异的抗坏血酸感测能力。在革兰氏阴性和革兰氏阳性细菌上也证实了该材料的高贵的抗菌活性。HRTEM(IFFT)/ SAED和CV / EIS分析。吸附动力学(吸附反应/吸附扩散)和吸附等温线测试证实了化学吸附类型的被吸附物/亚甲基蓝染料-吸附剂/ PTMO-NCM相互作用的存在。在刚果红和酸性橙8染料上测试了光催化性能。通过CV和安培分析可以了解该材料优异的抗坏血酸感测能力。在革兰氏阴性和革兰氏阳性细菌上也证实了该材料的高贵的抗菌活性。HRTEM(IFFT)/ SAED和CV / EIS分析。吸附动力学(吸附反应/吸附扩散)和吸附等温线测试证实了化学吸附类型的被吸附物/亚甲基蓝染料-吸附剂/ PTMO-NCM相互作用的存在。在刚果红和酸性橙8染料上测试了光催化性能。通过CV和安培分析可以了解该材料优异的抗坏血酸感测能力。在革兰氏阴性和革兰氏阳性细菌上也证实了该材料的高贵的抗菌活性。在刚果红和酸性橙8染料上测试了光催化性能。通过CV和安培分析可以了解该材料优异的抗坏血酸感测能力。在革兰氏阴性和革兰氏阳性细菌上也证实了该材料的高贵的抗菌活性。在刚果红和酸性橙8染料上测试了光催化性能。通过CV和安培分析可以了解该材料优异的抗坏血酸感测能力。在革兰氏阴性和革兰氏阳性细菌上也证实了该材料的高贵的抗菌活性。
