As a new type of crystalline porous material, the imidazole zeolite framework (ZIF) has attracted widespread attention due to its ultra-high surface area, large pore volume, and unique advantage easy functionalization.
Oxygen Evolution Reaction In article number 2201141, Jun Mei, Ziqi Sun and co-workers design a 2D/2D heterostructured electrocatalyst by coupling mildly oxidized black phosphorus with 2D nickel hydroxide to reach favorable electronic structure desired reconstructed surface towards high-performance alkaline oxygen evolution reaction catalysis.
A hydrogen bond-driven supramolecular strategy to synthesize multiphase-Fe anchoring on hierarchical N-doped graphitic carbon was proposed. As a result, the as-obtained catalysts showed unusual trifunctional activities in the oxygen reduction reaction, oxygen evolution reaction and hydrogen evolution reaction, even surpassing noble-metal catalysts such as Pt/C and RuO2.
Oxygen Evolution Reaction In article number 2207695, Byung-Hyun Kim, HyukSu Han, and co-workers develop an iridium doped calcium copper titanate exhibiting ultrahigh mass activity for acidic oxygen evolution reaction (OER). This work reposts the design of electrocatalysts OER using colossal dielectric perovskite oxide.
Understanding the pathways of catalyst degradation during the oxygen evolution reaction is a cornerstone in the development of efficient and stable electrolyzers, since even for the most promising Ir based anodes the harsh reaction conditions are detrimental. The dissolution mechanism is complex and the correlation to the oxygen evolution reaction itself is still poorly understood. Here, by cou...
Oxygen Evolution Reaction Most transition metal oxides undergo in situ catalyst reconstruction during the oxygen evolution reaction alkaline media. The results a positive or negative effect on performance. In article number 2101324, Alberto Vomiero and co-workers report electrochemical transformations of NiMoO4@Co3O4, facilitated by Mo leaching, which is one centers active sites responsible for...
The Mn-oxide/Nb:SrTiO3 photoelectrode for oxygen evolution reaction was investigated by in situ Mn K-edge XAFS spectroscopy under UV irradiation. The oxidization of the Mn oxide was observed via photoexcited carrier transfer, which results in the positive potential shift of the Mn oxide cocatalyst toward oxygen evolution reaction.
