Dynamic Transition Metal Network via Orbital Population Design Stabilizes Lattice Oxygen Redox in Stoichiometric Layered Cathodes.

Li-ion batteries employing stoichiometric layered Li metal oxides as cathodes are now reaching the energy density limits due to single cationic redox chemistry. Lattice oxygen redox (LOR) has been discovered in these materials, as a high-energy-density paradigm observed in Li-rich materials. Nevertheless, the origin of this process is not understood, preventing the rational design of better cathode materials.

Rapid Ozone Decomposition over Water-activated Monolithic MoO /Graphdiyne Nanowalls under High Humidity.

Catalytic ozone (O ) decomposition at high relative humidity (RH) remains a great challenge due to the catalysts poison and deactivation under high humidity. Here, we firstly elaborate the role of water activation and the corresponding mechanism of the promoted O decomposition over the three-dimensional monolithic molybdenum oxide/graphdiyne (MoO /GDY) catalyst. The O decomposition over MoO /GDY reaches up to 100 % under high humid condition (75 % RH) at room temperature, which is 4.

Dual Activation of Molecular Oxygen and Surface Lattice Oxygen in Single Atom Cu /TiO Catalyst for CO Oxidation.

The in-depth mechanism on the simultaneous activation of O and surface lattice O on one active metallic site has not been elucidated yet. Herein, we report a strategy for the construction of abundant oxygen activation sites by rational design of Cu /TiO single atom catalysts (SACs). The charge transfer between isolated Cu and TiO support generates abundant Cu and 2-coordinated O sites in Cu -O-Ti hybridization structure, which facilitates the chemisorption and activation of O molecules.

We demonstrate that the neighboring sp-hybridized C and Cu sites on the interface of the sub-nanocluster CuO/graphdiyne are the key structures to effectively modulate the O activation process in the bridging adsorption mode.
