Boosting oxygen evolution electrocatalysisviaCeO2engineering on Fe2N nanoparticles for rechargeable Zn–air batteries

“…15,16 With these considerations, Fe/N co-doped carbon-based materials are often used as ORR electrocatalysts. 2,14,[17][18][19] However, the strong adsorption interaction between the reaction intermediates and substances seriously affected the migration of oxygen species during the OER process, which accounted for the poor OER activity of Fe-N-C-based catalysts. For these reasons, most of the ZABs assembled by Fe-N-C-based catalysts cannot achieve longterm charging/discharging stabilities.…”

Developing a Se Quantum Dots@ CoFeOx Composite Nanomaterial as a Highly Active and Stable Cathode Material for Rechargeable Zinc–Air Batteries

“…Hence, various strategies have been put forward to improve the unsatisfactory activity or stability of iron oxides, including exposing active sites, reducing their nanoscale, and so on [27][28][29]. In recent years, designing composite materials with highly conductive additives has been widely reported to significantly improve their dispersion and catalytic activity [30][31][32]. For example, Wang et al reported short carbon nanotubes supporting nickel-iron oxides, where the carbon composite confers a high electrochemical surface area and satisfactory electron transfer ability [31].…”

For example, Wang et al reported short carbon nanotubes supporting nickel-iron oxides, where the carbon composite confers a high electrochemical surface area and satisfactory electron transfer ability [31]. Li et al synthesized heterostructural FeO x /Fe nanoparticles based on a nitrogen-doped carbon framework, which displayed high ORR activity and good durability due to the high electroconductivity and proper hydrophilicity of the carbon framework [33].…”
