W2N-MXene composite anode catalyst for efficient microbial fuel cells using domestic wastewater

2D MXenes Nanosheets for Advanced Energy Conversion and Storage Devices: Recent Advances and Future Prospects

“…All of these samples exhibited a comparable hydrogen crossover value of around 1.6 mA/cm 2 , which was clearly less compared to the pristine r-PEM hydrogen crossover value of 2.1 mA/cm 2 . Kolubah et al [135] presented a composite catalyst comprising of W 2 N-Ti 3 C 2 T x and evaluated as the anode in a microbial fuel cell (MFC) for the purpose of generating electricity during the process of wastewater treatment. SEM image of the W 2 N-Ti 3 C 2 T x composite (Figure 9d) shows that the Ti 3 C 2 T x structure is preserved in the material, and that the W 2 N is embedded in the interlayer spacings and on the MXene's surface.…”

Scope, evaluation and current perspectives of MXene synthesis strategies for state of the art applications

“…MXenes have been employed in various advanced applications: energy storage, 12–17 electronics, 18–21 environmental, 22–26 sensors, 27–33 catalysis 34–38 and biomedicine. 39,40 The advanced features and flexibility of MXene structures are the main causes of their diverse applications.…”

Carbon nanofiber/graphene hybrids anchoring Fe, N, and S heteroatoms simultaneously enhancing extracellular electron transfer and biofilm adhesion in microbial fuel cells

“…2,9,10 The ideal anode material should exhibit excellent electrical conductivity, biocompatibility, and abundant reactive sites, which could promote the extracellular electron transfer (EET) process and enhance the attachment of EAB. [11][12][13] Carbon-based materials are widely used as anode materials owing to their low cost. 9,10,14,15 However, MFCs with carbon-based materials as anodes typically exhibit lower power densities due to the sluggish EET and poor EAB colonization of these materials.…”
