Summary: A 3D superhydrophilic/superaerophobic hierarchical rod-sheet structure of NiFe-based layered double hydroxides coupled with cobalt carbonate hydroxide has been synthesized, showing excellent oxygen evolution reaction (OER) performances. The unique stepped hierarchical rod-sheet structure not only benefits the catalytic activity, electron transfer, and active sites exposure, but also promotes electrolyte diffusion and bubble release. Additionally, a water-splitting device assembled with this structure demonstrated stable operation for 200 hours. The strategy of engineering stepped hierarchical structures with synergistic effect may provide a new pathway for synthesizing highly efficient OER electrocatalysts.

Summary: Enhancing the electrochemical reaction kinetics is crucial for achieving high-performance anodes in lithium-ion batteries. In this study, vanadium-doped Cu2O microspheres (V-Cu2O) were synthesized on Cu foam through a facile hydrothermal method and heat treatment. The doping of vanadium induced the formation of radially oriented nanostructures and abundant oxygen vacancies in Cu2O. The V-Cu2O anode exhibited a reversible capacity of 1173 mAh/g after 100 cycles at a current density of 100 mA g-1, which can be attributed to the synergistic effect of fast kinetics from oxygen vacancies and additional capacity from vanadium ions. This work proposes a promising and effective strategy to enhance the Li-storage performance of anode materials.

Summary: In this study, a Ce-doped ZnO nanoarray (CZO) was successfully synthesized via a one-pot hydrothermal method and demonstrated as a promising NO2 chemiresistive sensing material. Ce doping not only changes the morphology of the initial ZnO nanoarray, but also introduces abundant oxygen vacancy. Gas sensing tests show that CZO-2 (Ce wt% = 2%) exhibits a 10fold higher sensing response to NO2 and much lower limit of detection (LOD = 1.4 ppb) compared to the initial ZnO nanoarray. High selectivity for NO2 and excellent long-term stability are also achieved in this Ce-doped sensor.

Summary: An electric-assisted peroxymonosulfate (PMS) activation system is developed for sustainable treatment of wastewater. S-doped CoO nanoflower grown on Ti plate (S-CoO/Ti) electrocatalyst is fabricated via one-step electrodeposition. The system generates energetic oxidative species (center dot OH, SO4 center dot-, O-2(center dot-), O-1(2) and Co4+), and Co4+ species are dominantly responsible for tetracycline (TC) degradation. Almost 100% TC removal is achieved within 20 min (C-0 = 25 mu M), and the S-CoO/PMS system shows superior performance in a wide pH range from 3 to 11.
