Abstract Mn‐based mullite oxides AMn 2 O 5 (A = lanthanide, Y, Bi) is a novel type of ternary catalyst in terms their electronic and geometric structures. The coexistence pyramid Mn 3+ –O octahedral 4+ makes the d‐orbital selectively active toward various catalytic reactions. alternative edge‐ corner‐sharing stacking configuration constructs confined sites abundant oxygen species. As result, they tend to show superior behaviors thus gain great attention environmental treatment energy...
Abstract Developing fast‐charging Zn–air batteries is crucial for widening their application but remains challenging owing to the limitation of sluggish oxygen evolution reaction (OER) kinetics and insufficient active sites electrocatalysts. To solve this issue, a reconstructed amorphous FeCoNiS x electrocatalyst with high density efficient sites, yielding low OER overpotentials 202, 255, 323 mV at 10, 100, 500 mA cm −2 , respectively, developed charging voltages 100–400 . Furthermore,...

Catalytic decomposition of aromatic polluters at room temperature represents a green route for air purification but is currently challenged by the difficulty generating reactive oxygen species (ROS) on catalysts. Herein, we develop mullite catalyst YMn2O5 (YMO) with dual active sites Mn3+ and Mn4+ use ozone to produce highly O* upon YMO.
