Atomically dispersed Mn–N₄ electrocatalyst with high oxygen reduction reaction catalytic activity from metal–organic framework ZIF-8 by minimal-water-assisted mechanochemical synthesis

Abstract

Developing efficient and stable non-precious metal (NPM) oxygen reduction reaction (ORR) catalyst in an environmentally benign and economically affordable way is highly desired but remains challenging. Manganese and nitrogen co-doped...

Facile synthesis of cobalt cluster-CoNx composites: synergistic effect boosts electrochemical oxygen reduction

“…), with comparable ORR performances are urgently required to be developed. [12][13][14][15][16] electro-catalytically active species of CoN x and Co clusters, [38][39][40] which is further corroborated by rst-principles calculations.…”

“…), with comparable ORR performances are urgently required to be developed. 12–16 Additionally, heteroatoms, especially nitrogen, have been well introduced into carbon matrixes for embedding TMs as catalytically active sites for boosting ORR performances. 17–21…”

Metal–organic framework-derived advanced oxygen electrocatalysts as air-cathodes for Zn–air batteries: recent trends and future perspectives

“…Recently, besides Fe-N-C and Co-N-C-based SACs, other non-precious metal-based SACs have been investigated as ORR catalysts and their performance towards ZABs have also been studied. [173][174][175][176][177][178][179][180][181][182][183] For example, Wu and co-workers reported a high-temperature gas-transport strategy to construct isolated Cu-SACs on N-doped carbon (Cu ISAS/NC) with rich defects using cost-effective and commercially available Cu 2 O (Fig. 18a).…”

Non-precious transition metal single-atom catalysts for the oxygen reduction reaction: progress and prospects

“…2a). 79 The selection of manganese salts for the preparation of precursors also plays an important role in whether the Mn species can easily form inert compounds during the pyrolysis process. The X-ray diffraction results are given in Fig.…”
