Bimetallic MCo (M=Cu, Fe, Ni, and Mn) nanoparticles doped-carbon nanofibers synthetized by electrospinning for nonenzymatic glucose detection

Facile synthesis of electrospinning Mn2O3-Fe2O3 loaded carbon fibers for electrocatalysis of hydrogen peroxide reduction and hydrazine oxidation

“…As can be seen in Fig. 1, the XRD patterns of samples all show a broad peak at about 2θ of 25.0 °, which corresponds to amorphous carbon [36]. Mn-based catalyst is beneficial to keep 3D net-like structure.…”

“…Mn-based catalyst is beneficial to keep 3D net-like structure. The distinctive structure may bring more advantages, such as large specific surface area and more exposed active sites for reactions [36,46]. EDS was also conducted to further confirm the composition of Mn 2 O 3 -Fe 2 O 3 /CFs (3:1).…”

“…Hence, better catalytic activity of manganese oxides is still expected. On the other hand, it has been proved that preparing composites is an effective way to enhance the catalytic properties, durability and utilization efficiency of the catalysts [36,37]. Inspired by the environment benignity, non-toxicity and cost-efficient of iron oxides [38][39][40], the catalytic effect of manganese-iron composites and the optimal proportion of Mn to Fe were studied in this work.…”

“…However, there are certain weaknesses in the preparation of transition metal oxides, such as the agglomeration and large size of particles. Over the last several decades, carbon fibers (CFs) have received considerable attention by the fascinating structure, high electrons transfer property and abundant exposed active sites [36]. Electrospinning is a simple and effective avenue to the quantity production of polymer fibers from all kinds of precursors [44,45].…”

Cobalt/Chromium Nanoparticles-Incorporated Carbon Nanofibers as Effective Nonprecious Catalyst for Methanol Electrooxidation in Alkaline Medium

“…Compared to nanoparticles, the large axial ratio provides the nano¯ber catalytic materials good priority especially in case of utilization in the electron transfer-based processes. 7 Carbon nano¯bers (CNFs) are widely used in many applications including dye sensitized solar cells, 8 high performance supercapacitor, 9 nonenzymatic glucose detection, 10 capacitive deionization, 11 lithium-ion rechargeable batteries 12 and DMFCs. 13 Poly(vinyl alcohol) (PVA) has high carbon content (ca.…”
