Suppressing Formation of Zn─Mn─O Phases by In Situ Ti Decoration of MnO for Long Lifespan MnO-Zn Battery.

Mildly-acidic MnO-Zn batteries are considered as a promising alternative for large-scale energy storage systems for their low toxicity, high safety, and low cost. Though, the degradation of MnO with cycling still hinders the further development of the batteries. In this study, it is observed that the decrease in available capacity of MnO with charge and discharge is accompanied by a structural transformation with the emergence of Zn─Mn─O phases.

Atom-stepped surface-regulated Pd nanowires for boosting alcohol oxidation activity.

A highly active surface can endow the electrocatalysts with extraordinary catalytic performances. However, it remains challenging to tailor the atomic packing characteristics and thus the physical and chemical characteristics of the electrocatalysts. Herein, penta-twinned Pd nanowires (NWs) with abundant high-energy atomic steps (i.
