The synthesis of Co_xNi_1−xFe₂O₄/multi-walled carbon nanotube nanocomposites and their photocatalytic performance

Abstract

A series of CoxNi1−xFe2O4/multi-walled carbon nanotube (CoxNi1−xFe2O4/MWCNTs) nanocomposites as photocatalysts were successfully synthesized. The results implied that this composites can be effectively applied for the removal of organic pollutant as novel photocatalysts.

Integrated Photothermal Nanoreactors for Efficient Hydrogenation of CO2

“…The formation of polycrystalline Co particles was also revealed by the selected area electron diffraction pattern of Co@SiO 2 (Fig. S8) [37,38]. In particular, the XRD pattern of the small-sized Co assigned to the CoO phase mainly resulted from the inevitable surface oxidation of Co nanoparticles during the sample preparation.…”

Chemoselective reduction of nitro and nitrile compounds using an Fe3O4-MWCNTs@PEI-Ag nanocomposite as a reusable catalyst

“…39,40 In addition, while there are interesting achievements with noble metal functionalized magnetic carbon nano/microtubes, for example, in catalysis and sensors, [41][42][43] other low dimensional nanocarbon scaffolds are actively pursued by the researchers, [44][45][46][47][48][49][50] and are going to nd application in energy materials. [51][52][53][54][55][56][57][58][59][60] Herein, we introduce Fe 3 O 4 -MWCNTs@PEI as a novel support for uniform dispersion of Ag NPs over its surface, and application of the Fe 3 O 4 -MWCNTs@PEI-Ag hybrid material as an efficient catalyst for chemoselective reduction of nitro and nitrile compounds to amines in aqueous solution under very mild and green conditions.…”
