1Synthesis and characterization of a new magnetic bromochromate hybrid nanomaterial with triethylamine surface modified iron oxide nanoparticles显示文摘We describe a novel method for the synthesis a new magnetic bromochromate hybrid nanomaterial,Fe_3O_4@SiO_2@TEA@[CrO_3Br],as a catalyst.The physical properties,morphology and magnetic investigations of magnetic bromochromate hybrid naiiomaterials are identified by transmission electron microscopy(TEM),scanning electron microscopy(SEM) and vibrating sample magnetometer(VSM) techniques.Fourier transform infrared(FT-IR),elemental analysis,X-ray fluorescence(XRF),X-ray diffraction(XRD) were also used for structural identification.The quantity of chromium is approximately 0.38%,which confirms to the immobilization amount of[CrO_3Br]and is equal to 0.007 mol/100 g.Rahmatollah Rahimi Ali Maleki Saied Maleki 2014Chinese Chemical Letters2014,25,6:1
2Effect of solvent on Se-modified ruthenium/carbon catalyst for oxygen reduction显示文摘Se-modified ruthenium supporting on carbon(Sex–Ru/C) electrocatalyst was prepared by solvothermal one-step synthesis method. The reaction mechanism was revealed after discussing impact of different solvents(i-propanol and EG) in solvotermal reaction. The result showed that the grain size of Se-modified ruthenium electrocatalyst was as small as 1 to 3 nm and highly dispersed on carbon surface. X-ray photoelectron spectroscopy(XPS) presented that selenium mainly existed in the catalyst in the form of elemental selenium and selenium oxides when the solvent was EG and i-propanol, respectively. The oxygen reduction reaction(ORR) performance was improved by appearance of selenium oxides.Chuanxiang Zhang Haijun Tao Yuming Dai Xiancong He Kejie Zhang 2014Progress in Natural Science:Materials International2014,24,6:0
3具有对称结构的吡咯并[3,4-b]喹啉-1-酮衍生物的超声辅助合成及荧光性能显示文摘以6-氯-2-氯甲基-3-喹啉甲酸乙酯(1)为底物,在无水乙醇中经超声辅助下分别与对苯二胺(2)和联苯二胺(3)中的两个氨基反应,得到具有对称结构的吡咯并[3,4-b]喹啉-1-酮衍生物(4,5).所合成的化合物未见文献报道,其结构经红外光谱、核磁共振氢谱、核磁共振碳谱和高分辨质谱得以确定.对化合物4和化合物5及过去报道的化合物6a-l进行荧光光谱测定,结果表明化合物4和化合物5及化合物6a-g具有较好的荧光性能.符鑫博 王东方 赵雅楠 李阳 高文涛 2016化学研究2016,27,5:0
