Cu-doped alpha-Fe2O3Porous spindlesGas sensorTEAThe introduction of other elements can be an effective method to promote gas sensing performances in recent years due to the generation of oxygen vacancy defects. In this work, by using MIL-88-Fe as the precursor, Cu-doped α-Fe2O3 porous ...
alpha-Fe2O3 and Cu- doped alpha-Fe2O3 microspheres were similarly synthesized by solvothermal method. These microspheres were characterized by X- ray diffraction (XRD), and scanning electron microscope (SEM) technique. As anode materials for lithium- ion batteries (LIBs), Cu-doped alpha-Fe2O...
Non-thermal plasma assisted synthesis and physicochemical characterizations of Co and Cu doped Ni/Al 2 O 3 nanocatalysts used for dry reforming of methane and well dispersed particles of active sites in Ni Co/Al2O3 nanocatalyst were observed that shows the effect of cobalt in controlling Ni ...
采用两步法,采用水热法以Fe(NO_3)_3·9H_2O、Cu(NO_3)_2·5H_2O作为前驱体,水为溶剂,正丙醛为还原剂,制备了CuFeO_2微米颗粒.为进一步提高其催化活化H_2O2的性能,使用硼氢化钠对其进行了还原处理制备微米CuFe/CuFeO_2催化剂.利用XRD、SEM和XPS对其进行了物相,形貌和表面元素的表征,结果表明所制备的...
We also synthesized 10 at% Cu doped Fe2O3 by a similar method. It is found that the hydrolysis activity of 10CuFe2O3 is lower than that of 10CuCo3O4, as shown in Fig. S2. Notably, 10CuCo3O4 has the highest oxygen vacancy contents, surface area and the strongest interaction ...
Nanocrystalline and bulk samples of "Fe"-doped CuO were prepared by coprecipitation and ceramic methods. Structural and compositional analyses were performed using X-ray diffraction, SEM, and EDAX. Traces of secondary phases such as CuFe2O4, Fe3O4, and 伪-Fe2O3 having peaks very close to ...
Three-Dimensional Fe2O3 Nanocubes/Nitrogen-Doped Graphene Aerogels: Nucleation Mechanism and Lithium Storage Properties We developed a solvothermal-induced self-assembly approach to construct three dimensional (3D) macroscopic Fe2O3 nanocubes/nitrogen-doped graphene (Fe2O3-NC/GN) aerogel as anode mater...
A low cost hydrothermal method and subsequent wet-chemical process has been used for the preparation of a ZnO nanorod (NR) array film grown on tin doped indium oxide (ITO) coated glass substrates, post decorated by α-Fe2O3 nanoparticles (NPs). The effect of the amount of α-Fe2O3 NPs...
Active metal atoms (Fe/Cu) are anchored to the holey edge sites of nitrogen-doped graphene (HNG), forming a "Y-type" ML3 coordination with two nitrogen atoms and one metal atom. Fe and Cu atoms bind together to form a dimer structure inside the holes (Fig. 1a). The resultant ...
CuFe2O4/Ag nanoparticle has also been used as a catalyst due to high surface area and mesoporous structure [17]. Fe3O4 ferrites have gained tremendous attention in nanomaterial research. Recent studies shows that they are emerging as potential materials in the field of catalysis, super ...
