F127-assisted preparation of FeCo nanoalloys encapsulated in nitrogen-doped carbon for efficient oxygen reduction reaction

Abstract

Exploring cost-effective electrocatalysts for oxygen reduction reaction (ORR) is a prerequisite yet challenge for many energy conversion and storage systems. The direct pyrolysis of zeolitic imidazolate framework (ZIF) materials has...

Amorphous zeolite imidazole framework-derived hierarchically porous and multi-catalytic active site bifunctional catalysts for zinc–air batteries

“…But, excessive Fe may lead to more Co removal from Co–NC sites to form CoFe alloy sites, thus degrading the catalytic performance. 46,47 So, the molar ratio of Fe and Co is a crucial parameter which may affect the electrocatalytic performance of the synthesized samples. 48 Fig.…”

A hierarchical V2O3@C hollow microsphere cathode with high performance for zinc-ion batteries

“…Aqueous zinc ion batteries (ZIBs) have attracted great attention for large-scale energy storage applications, due to their safety, non-toxicity and low cost. [1][2][3][4][5] Since zinc metal is usually used in ZIBs, great efforts have been made to explore cathode materials including manganese-based materials, 6,7 vanadium-based materials, 8,9 Prussian blue analogues, 10,11 and organic electrode materials. 12,13 Among them, vanadium-based materials as cathodes have great potential because of their own multivalency, large theoretical specific capacity, and diverse crystal structures.…”

Enhancing the catalytic performance of Co–N–C derived from ZIF-67 by mesoporous silica encapsulation for chemoselective hydrogenation of furfural

“…Due to the massive exploitation and use of fossil energy, the energy crisis and environmental pollution on earth are becoming increasingly serious and it is extremely pressing to find alternatives to fossil energy. 1,2 Biomass is one of the most abundant renewable energy sources and it can be transformed into biofuels and highly value-added chemicals through selective hydrogenation, oxidation, decarbonylation, and so on. [3][4][5][6][7] Furfural, as one of the major biomass-based platform molecules, can be converted into furfuryl alcohol, furan and other chemicals (Scheme 1).…”
