The materials elucidation was effected using SEM, TEM, ATR-FTIR, XRD and nitrogen adsorption鈥揹esorption. The heterogeneous catalytic property of the 尾-FeOOH/polyamide nanocomposites was evaluated in an aqueous ozonation system with 4-chlorophenol (4CP) as the target organic pollutant. Aliquots ...
a用水热法制备表面活性剂修饰过的铁晶须,并用X射线衍射(XRD)、场发射扫描电子显微镜(SEM)、透射电子显微镜(TEM)对其形貌及结构进行表征。通过用无机铁盐与不同的表面活性剂制备出的β-FeOOH纳米线, 并用透射电子显微镜(TEM)、场发射扫描电子显微镜(SEM)、X射线衍射(XRD)对其形貌及结构进行了表征。结果表明,不同...
The obtained solid sample was proved to be β -FeOOH by XRD technology and spindle-shaped by TEM technology. The coexisting NH 3 molecules may be the main reason for the stable nanofluid. The weak bonding between nitrogen and iron atoms would be formed. The investigation on the excess heat...
beta-FeOOH particles were prepared by forced hydrolysis of FeCI_3 centre dot 6H_2O in microemulsion containing polyoxyethylene nonylphenylether (NP-4), octane and water. The samples were characterised using XRD and TEM. The effects of the molar ratio of water to NP-4 R, initial Fe~(3+) ...
(beta-FeOOH/PANI, about 1.0 mu m) could be successfully composed by polyaniline (PANI, (C6H7N)n, 200-300 nm) and akaganeite (beta-FeOOH, FeO(OH)(1-x)Cl-x, less than 200 nm), according to the identification and characterization results of XRD, Ramon, FTIR, XPS, SEAD, EDS, and...
Details of the coloration and phase structure of beta-FeOOH were characterized by UV-vis, CIE Lab color parameter measurements, TEM (transmission electron microscopy), SEM (scanning electron microscopy), and XRD (powder X-ray diffraction).
Akaganeite (β-FeOOH) nanoparticles were successfully anchored on the surface of porous sea buckthorn biocarbon (SBC) via a simple low-temperature hydrothermal process without use of surfactants or external forces. The SBC@β-FeOOH composite was characterized by X-ray diffraction (XRD), scanning ...
Influence of phosphate on the crystallization of alpha-Fe_2O_3 at 160 deg C from concentrated FeCl_3 solution partially neutralized with concentrated NaOH solution was investigated by ~(57)Fe Mossbauer, XRD, FT-IR and FE-SEM. In the reference precipitation system, without phosphate addition, ...
beta#-FeOOH particles were prepared by aging aqueous FeCl_3 solutiohs containing Ti(IV),Cr(III),and Cu(II) at room temperature for 360 days.The structures of the formed particles were investigated by various techniques including TEM,XRD,XAFS,and adsorption of N_2 and H_2O.Ti(IV) ...
