Interfacial Activation of Catalytically Inert Au (6.7 nm)-Fe3O4 Dumbbell Nanoparticles for CO Oxidation

Starting from various supported Au (6.7 nm)-Fe3O4 catalysts prepared by the colloidal deposition method, we have unambiguously identified the significance of the Au-TiO2 interface in CO oxidation, without any possible size effect of Au. In situ thermal decomposition of TiO2 precursors on Au-Fe3O4 was found to be an effective way to increase the Au-TiO2 interface and thereby optimize the catalytic performance of TiO2-supported Au-Fe3O4 dumbbell nanoparticles. By reducing the size of Fe3O4 from 15.2 to 4.9 nm, the Au-TiO2 contact was further increased so that the resulting TiO2-supported Au (6.7 nm)-Fe3O4 (4.9 nm) dumbbell particles become highly efficient catalysts for CO oxidation at room temperature.National Natural Science Foundation of China 20871100 20721001 Distinguished Young Investigator Grant 20925103 Research Fund for the Doctoral Program of Higher Education of China 200803841010 Natural Science Foundation of Fujian 2009J06005 Key Scientific Project of Fujian Province 2009HZ0002-

目的:观察非酒精性脂肪肝(NAFLD)患者不同中医证型与临床指标、肝活检病理学的关系。方法:选择312例NAFLD患者进行辨证分型,均进行肝组织活检,常规判定NAFLD活动度积分(NAS)和肝纤维化分期。结果:NAFLD患者的中医证型频数分布为痰湿内阻证>肝郁脾虚证>湿热蕴结证>肝郁气滞证>痰瘀互结证。NAFLD患者性别、年龄、病程、血生化、体质量指数、肝硬度值、NAS积分等指标在不同中医证型的分布差异具有统计学意义(P<0.05)。结论:NAFLD患者痰湿内阻证、痰瘀互结证、湿热蕴结证三型NAS积分较高,故NAFLD的治疗应着重于健脾化痰、清热利湿、活血化瘀。国家自然科学基金项目(No.81503529,No.81673660,No.81873242);;福建省科技计划引导性项目(No.2015D007,No.2016D012);;厦门市科技计划项目(No.3502Z20174028);;厦门市重要重大疾病联合攻关项目(No.3502Z20179047);;福建省卫生计生医学创新科研人才培养项目(No.2018-CXB-28);;福建中医药大学基金项目(No.XB2016080);;陈国良名老中医传承工作室(厦门市卫生局资助项目);;全国第六批老中医药专家学术经验继承工作(2017年)~

Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to characterize the morphology and crystal phase of the ZnO nanorods. The data showed that the ZnO nanorods were wurtzite type crystals with a hexagonal rod shape and a diameter of about 100 nm and that the ZnO nanorods were arranged well on the surface of electrodes. These ZnO nanorod-modified electrodes were able to detect direct electron transfer from cytochrome c (cyt c). Cyclic voltammograms showed that the direct electron transfer of cyt c with heme iron in different valence states was easily achieved by the ZnO nanorod/Au electrode. Data of amperometric responses demonstrated that a linear amperometric response to hydrogen peroxide was observed on the ZnO nanorod/Au electrodes after adsorbing cyt c.国家自然科学基金(20603027,21021002,20973134); 国家高技术研究发展专项经费项目(2009AA03Z327)资
