S/N codoped carbon nanotubes as an efficient ORR electrocatalyst for zinc–air batteries

Abstract

The development of low-cost non-noble metal ORR catalysts has important practical significance for the development of fuel cells and metal-air battery. In this work, an S/N codoped carbon nanotube was...

Chemical fabrication and synergistic mechanism of N-doped carbon modified with FeP as catalysts for flexible rechargeable Zn–air batteries

“…However, the scarcity, high price, and poor stability of these noble metal-based electrocatalysts severely hinder the widespread application of rechargeable ZABs. [9][10][11] Therefore, the development of cost-efficient bifunctional and highperformance electrocatalysts for the ORR and OER is urgent for exible rechargeable ZABs.…”

Enhancement of the characteristics and HER activity of molybdenum carbide nanosheets for hydrogen evolution reaction

“…7 Electrocatalysts usually consist of noble metals, and their high cost, scarcity and poor long-term stability make them unsuitable for commercial purposes. [8][9][10][11] Although several other electrocatalysts have been developed, their structural stability, internal voltage loss, low electrical conductivity, and cost are a big hindrance to their practical application at the industrial level. 12 Efficient electrocatalysts exhibit high electrical conductivity, large specic surface area, structural stability, low Gibbs free energy, rich surface chemistry, and more active sites.…”

Heterostructure CoFe@(Co0.5Fe0.5)S@NCNT anchored on rice husk-based hierarchical porous carbon as a bifunctional cathode catalyst for Zn–air batteries

“…3 Metal-free catalysts (MFCs) offer a cost-effective alternative to PMCs, modulating catalytic activity through the synergistic effect of defects and doping, 4 and exhibit comparable catalytic activity. [5][6][7] A more effective strategy for enhancing the performance of the OER and ORR in heterogeneous electrocatalysts involves non-precious metal catalysts (non-PMCs) with MFCs synergistically constructing rational heterostructures. [8][9][10] These encompass single transition metal nanoparticles, transition metal alloy nanoparticles, and transition metal compounds.…”
