In situ synthesis of cylindrical spongy polypyrrole doped

Herein, we demonstrate the exfoliation of bulk graphitic carbon nitrides (g-C3N4) into ultra-thin (~3.4nm) two-dimensional (2D) nanosheets and their functionalization with proton (g-C3N4H(+)). The layered semiconductor g-C3N4H(+) nanosheets were doped with cylindrical spongy shaped polypyrrole (CSPPy-g-C3N4H(+)) using chemical polymerization method.

METHOD FOR PRODUCING A FUNCTIONALIZED

Electrochemical Exfoliation and In Situ Functionalisation of Graphite with Polypyrrole and Production of a Dispersion of Polypyrrole-Functionalised Graphene (EG-PPy) The graphite exfoliation was carried out in a two-electrode system, wherein graphite foils (2 cm3 cm, 100 mg per foil) (Alfa Aesar, 99.99% purity) were used as working anodes and gold foils of the same dimensions were used as

MoS2‐Based Nanocomposites for Electrochemical Energy

The electrochemical performance of different MoS 2 content (47%, 73%, and 95%) in carbon nanofibers is presented in Figure 4s,t, demonstrating that the MoS 2 /C‐47 maintains the most stable cycling performance and rate capacity. 84 Moreover, Wang et al 85

During the past 10 years, the synergistic interactions between nanotechnology and biotechnology have resulted in innovative functional biological nanosystems with potential applications in biotechnology, biosensing, and biomedical areas. The development of effective nanobiocatalysts, in which enzymes are immobilized onto robust nanostructured materials with tailor-made properties, is a typical

High

For the electrochemical exfoliation, a novel IL/acetonitrile electrolyte is introduced, and investigated with low concentration of ionic liquids. Using iso-molded graphite rod as the anode, up to 86% of exfoliation was achieved with the majority of the products as graphene flakes in addition to smaller quantities of carbonaceous particles and rolled sheets.

Two

Hence, in the conventional electrochemical exfoliation, the cointercalated water molecules tend to decompose to oxygen gaseous products, which expand and exfoliate the graphite. Oxidation and exfoliation of higher-stage GICs ( n ≥ 2) will follow the combined mechanisms discussed above, leading to a mixture of EGO and exfoliated graphene.

2019/9/1Electrochemical exfoliation is one of a handful of potentially cost-effective and scalable methods for converting graphite to graphene [,,,,,, ]. As an essentially wet chemical approach, electrochemical methods have the advantage of being green (avoiding hazardous or energy intensive processes), using low-cost and readily available precursors, and allowing for a large degree of
