TiN Boosting the Oxygen Reduction Performance of Fe–N–C through the Relay-Catalyzing Mechanism for Metal–Air Batteries

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 22, 2025

Metal–air batteries desire highly active, durable, and low-cost oxygen reduction catalysts to replace expensive platinum (Pt). The Fe–N–C catalyst is recognized as the most promising candidate for Pt; however, its durability hindered by carbon corrosion, while activity restricted due limited reaction. Herein, TiN creatively designed be hybridized with (TiN/Fe–N–C) relieve corrosion absorb more when catalyzing reduction. half-wave potential of TiN/Fe–N–C 0.915 V vs reverse hydrogen electrode 15 mV lost after 30,000 cycles accelerated test, higher than 0.893 26 Pt/C. solid zinc–air battery achieves a peak power density 238 mW/cm2, 2100 cycle stability at 30 °C, long-term 1100 h under −20 superior 150 mW/cm2 500 (−20 °C) Both calculations experiments indicate that has dual functions which not only relay abundant reaction but also strengthen adsorption force intermediates reaction, thus, enhancing Fe–N–C. Therefore, proposed catalytic strategy offers an efficient energy conversion devices.

This study focused on examining how the presence of a TiO 2 nanotube (NT) interlayer and decreasing particle size affects electrochemical performance service life PbO -coatings titanium substrate. The Ti/TiO -NT/ β -PbO Ti/PbO electrodes were synthesized using direct current with 3 μm optimized density values, while -NT/nano 35 nm simple pulse electrodeposition method duty cycle. results cyclic voltammetry demonstrated that -NT/nanoPbO electrode exhibited larger electrochemically active surface area, charge values 3.06 mC cm −2 , lower transfer resistance 9.47 Ω.cm compared to -NT/microPbO which had 9.26 14.62 61.58 8900 respectively. Accelerated tests showed /nanoPbO (55 h) better than those (50 18 h respectively). Moreover, highest in degrading methylene blue simulated wastewater by bulk electrolysis, removal efficiency approximately 100% at optimal (60 mAcm ), surpassing (76%) (53%).

Will Iron Forge the Future of Metal‐Air Batteries in Grid Scale Energy Storage?

ChemSusChem, Journal Year: 2025, Volume and Issue: unknown

Published: March 17, 2025

Abstract The community is exploring sustainable alternatives for grid‐scale energy storage. Besides lithium‐ion batteries (LIBs), such technologies with a focus on sustainability aspects offer only limited solution Rechargeable metal‐air (MABs) based affordable abundant multivalent metal anodes in aqueous medium provide promising theoretical metrics, as volumetric capacity, but do not completely fulfill their potential when scaled from lab to commercial products. Both the anode and air cathode need be addressed: corrosion, hydrogen evolution reaction (HER) during charging, passivation all diminish anode's effective density shelf life, while cathode's challenges include sluggish kinetics, low efficiency, poor stability. Nevertheless, this Perspective highlights iron‐air MABs an appealing alternative storage, since iron affordable, recyclable, has multielectron reversible redox activity, historically rich experience production processing, safe handle. Given that further research will directed composition design of electrolytes electrodes, it may lead advances scaling commercialization, well reducing environmental impact secondary utilized storage next decades.
