A Kinetic Control Strategy for One-Pot Synthesis of Efficient Bimetallic Metal-Organic Framework/Layered Double Hydroxide Heterojunction Oxygen Evolution Electrocatalysts

Guomei Mu et al.

Summary: A one-pot formation of bimetallic metal-organic framework (MOF)/layered double hydroxide (LDH) heterojunction electrodes is achieved through kinetic controlled synthesis for efficient oxygen evolution reaction (OER) electrocatalysis. The heterojunction electrodes show hierarchical structures, promoting fast mass transport and high exposure of active sites. The strong interactions at the MOF/LDH heterojunction interfaces contribute to outstanding OER activity surpassing state-of-the-art RuO2 catalysts.

Multilayer hollow MnCo2O4 microsphere with oxygen vacancies as efficient electrocatalyst for oxygen evolution reaction

Kai Zeng et al.

Summary: The article presents a novel multilayer hollow MnCo2O4 microsphere enriched with oxygen vacancies induced by plasma engraving. The defective microsphere exhibits excellent catalytic activity and durability compared to the pristine form. The improved electrocatalytic performance is mainly attributed to the abundant active sites generated by plasma treatment and the effects of introduced oxygen vacancies.

Influence of Fe and Ni Doping on the OER Performance at the Co3O4(001) Surface: Insights from DFT plus U Calculations

Yuman Peng et al.

Summary: In this study, the oxygen evolution reaction (OER) at the Co3O4(001) surface was investigated using density functional theory calculations with an on-site Hubbard U term. The results show that the termination with octahedral Co and O ions (B-layer) has the lowest overpotential, and doping with Fe and Ni can effectively reduce the overpotential. Additionally, changes in oxidation states of surface ions and active sites of Co during OER were analyzed to gain further insight into the behavior of the system.
