Interfacing MnO and FeCo alloy inside N-doped carbon hierarchical porous nanospheres derived from metal–organic framework to boost high-performance oxygen reduction for Zn–air batteries

Abstract

Efficient and strong non-precious metal catalysts are urgently needed for oxygen reduction reaction (ORR). Here, a facile hydrothermal-pyrolysis process was implemented to engineer CoFe-MnO heterointerfaces encapsulated in N-doped carbon (CFM-NC)...

A macroporous carbon nanoframe for hosting Mott–Schottky Fe–Co/Mo2C sites as an outstanding bi-functional oxygen electrocatalyst

“…17,18 Typically, the coupling of metals or alloys with semiconductor materials can facilitate directed charge migration at the interface through the generation of an inherent electric field. 19 This can optimize the d-band center of the catalyst and regulate the adsorption and desorption energy barriers of reaction intermediates in electrocatalytic processes, thereby offering the potential for synergistically enhanced ORR-OER electrocatalytic performance. 20 As an illustration, Wang et al have developed a durable bifunctional electrocatalyst consisting of Mott-Schottky Co 9 S 8 -Co on a reduced graphene oxide substrate, which shows potential for use as a reversible oxygen electrode in rechargeable ZAB application.…”

Customized Synthesis of MOF Nanoplates via Molecular Scalpel Strategy for Efficient Oxygen Reduction in Zn−Air Batteries

“…[7] In the past two decades, MOFs have also drawn markedly increasing attention due to their customizable pore size, ordered pore channels, structural diversity, and large specific surface area. [8] These characteristics give MOFs great potential for fluorescence, [9] sense, [10] drug load, [11] catalysis, [12] gas storage and separation, [13] and energy conversion. [14] Diminishing the size of MOFs to the nanoscale is a feasible and attractive direction for further expansion of MOFs applications.…”
