Achievements and Challenges in Surfactants‐Assisted Synthesis of MOFs‐Derived Transition Metal–Nitrogen–Carbon as a Highly Efficient Electrocatalyst for ORR, OER, and HER

Small, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 28, 2024

Abstract Metal–organic frameworks (MOFs) are excellent precursors for preparing transition metal and nitrogen co‐doped carbon catalysts, which have been widely utilized in the field of electrocatalysis since their initial development. However, original MOFs derived catalysts greatly limited development application due to disadvantages such as atom aggregation, structural collapse, narrow pore channels. Recently, surfactants‐assisted attracted much attention from researchers advantages hierarchical porous structure, increased specific surface area, many exposed active sites. This review mainly focuses on synthesis methods comprehensively introduces action surfactants materials structure‐activity relationship between oxygen reduction reaction, evolution hydrogen reaction performance. Apparently, aims this not only introduce status but also contribute rational design fuel cells, metal–air electrolysis water toward production.

Published: Aug. 8, 2024

Abstract Metal‐air secondary batteries with ultrahigh specific energies have received vast attention and are considered new promising energy storage. The slow redox reactions between oxygen‐water molecules lead to low efficiency (55–71%) limited applications. Herein, it is proposed that the MIL‐68(In)‐derived porous carbon nanotube supports CoNiFeP heteroconjugated alloy catalyst an overboiling point electrolyte achieve oxidation rate of water molecules. Structural characterization density functional theory calculations reveal greatly reduces free process, further accelerates dissociation O─H hydrogen bonds, release O 2 molecules, achieving extra‐low overpotential 110 mV@10 mA cm −2 far lower than commercial Ir/C catalysts 192 mV at 125 °C state‐of‐the‐art. Furthermore, assembled rechargeable zinc‐air begins break through 85 °C, jumps 100 reaches 88.1% ultralow decay 0.0068% after 150 cycles superior those reported metal‐air batteries. This work provides a joint‐design strategy reexamines battery operating temperature construct higher for fuel cells.
