Biomass chitosan-derived Co-induced N-doped carbon nanotubes to support Mn₃O₄ as efficient electrocatalysts for rechargeable Zn–air batteries

Abstract

Exploring efficient and low-cost electrocatalysts toward oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is extremely desirable for the commercial application of rechargeable Zn-air battery. Herein, we developed a...

Manganese, nitrogen co-doped porous carbon with high-loading active sites as the oxygen reduction catalyst for Zn–air batteries

“…In order to achieve carbon neutrality goals and accelerate the development of an environment-friendly society, the next generation of clean energy devices, including Zn-air batteries (ZABs), has garnered signicant attention because of low pollution features. [1][2][3][4][5][6][7][8][9][10][11][12] However, the actual performance of ZABs is limited by the slow ORR kinetics. [13][14][15][16][17][18][19] As benchmark catalysts for the ORR, Pt-based catalysts are costly and prone to instability, making them unsuitable for widespread commercial applications.…”

Bamboo derived N-doped carbon as a bifunctional electrode for high-performance zinc–air batteries

“…7–9 Therefore, considerable efforts have been made to develop non-precious metal carbon-based ORR/OER electrocatalysts, such as transition metal oxides/alloys, metal-free carbon-based catalysts, etc. 10–14 Among the various metal-free carbon-based materials, N-doped metal-free carbon-based catalysts (NC-MFCs) are considered to be one of the most promising candidates. 15,16 Reliance on precursor or template (carbon nanotubes, 17 graphenes, 18 carbon fibers, 19 MOFs, 20 Al 2 O 3 , 21 SiO 2 , 22 etc. )…”
