Abstract

ZnO flowers with different Ag contents were successfully synthesized by a simple microwave method. Phase and morphologies of heterostructure Ag/ZnO composites were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and X-ray photoelectron spectroscopy. The results showed that heterostructure Ag/ZnO composites were composed of face centered cubic Ag supported on hexagonal ZnO flowers of hexagonal prism nanorods with 100 nm wide and about 2–3 μm long, including the detection of Ag 3d_5/2 and Ag 3d_3/2 for metallic Ag of 10 wt% Ag/ZnO composites. The photocatalytic activity of heterostructure Ag/ZnO composites was evaluated through photodegradation of methylene blue under UV light. Escherichia coli DH5α (gram-negative bacteria) and Stapphylococcus aureus ATCC 25923 (gram-positive bacteria) were used to test for antibacterial activity. The 10 wt% Ag/ZnO composites showed the best performance for photocatalysis and had the antibacterial activity.

ZnO花负载银纳米粒子的微波辅助合成、光催化及抗菌活性研究

用简单的微波法制备了不同银含量的ZnO花。采用x射线衍射、扫描电镜、透射电镜和x射线光电子能谱对异质结构Ag/ZnO复合材料的物相和形貌进行了表征。结果表明，异质结构Ag/ZnO复合材料由面心立方银支撑在宽100 nm、长约2 ~ 3 μm的六边形棱镜纳米棒的六边形ZnO花上组成，其中Ag 3d5/2和Ag 3d3/2对10 wt% Ag/ZnO复合材料金属银的检测。通过紫外光降解亚甲基蓝，考察了异质结构Ag/ZnO复合材料的光催化活性。用大肠杆菌DH5α(革兰氏阴性菌)和金黄色葡萄球菌ATCC 25923(革兰氏阳性菌)检测其抑菌活性。10 wt% Ag/ZnO复合材料的光催化性能最好，且具有抗菌活性。

期刊介绍： The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems. Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal: Low-dimensional systems Exotic states of quantum electron matter including topological phases Energy conversion and storage Interfaces, nanoparticles and catalysts.
