Facile Preparation of Hierarchical AgNP-Loaded MXene/Fe₃O₄/Polymer Nanocomposites by Electrospinning with Enhanced Catalytic Performance for Wastewater Treatment

Abstract

MXene as a kind of two-dimensional nanomaterial has aroused people’s strong research interest because of its excellent properties. In the present study, we introduced a new poly(vinyl alcohol)/poly(acrylic acid)/Fe 3 O 4 /MXene@Ag nanoparticle composite film fabricated by electrospinning and heat treatment as well as self-reduction reaction process. The obtained composite films showed high self-reduction ability because of the incorporation of MXene flakes. The intercalated MXene flakes in the composite nanofibers were evenly distributed, which not only solved the aggregation problem from MXene dispersion but also could self-reduce Ag nanoparticles in situ in composite materials. In addition, the composite nanofiber films exhibited good fiber structure, thermal stability, and magnetic properties. Moreover, the composite nanofiber films demonstrated excellent catalytic ability and cycle stability to 4-nitrophenol and 2-nitroaniline.

Preparation of Palladium Nanoparticles Decorated Polyethyleneimine/Polycaprolactone Composite Fibers Constructed by Electrospinning with Highly Efficient and Recyclable Catalytic Performances

“…The kinetic constant k of the above catalytic reduction reaction was calculated to be 0.16597s −1 and 0.00401 s −1 , respectively. The kinetic constant k could intuitively reflect the speed of the catalytic reduction reaction [58][59][60][61][62][63][64][65]. Obviously, PEI/PCL@PdNPs catalytically reduced 4-NP faster.…”

The surface-enhanced resonance Raman scattering of dye molecules adsorbed on two-dimensional titanium carbide Ti3C2Tx (MXene) film

“…2,5,16 It has been reported that another family of 2D materials, transition metal carbides and nitrides (MXenes) can be used as SERS substrates [10][11][12][13]15 and for other applications. [17][18][19] Both the structure and electronic properties of MXene-Ti 3 C 2 T x were largely affected by the functional groups on the MXenes where X = -F, -O and -OH. 11,[20][21][22] Density functional theory (DFT) simulations have reported on the band diagrams and the optical properties of monolayer MXenes; however, the obtained values are yet to be verified by experimental measurements.…”
