A Universal Strategy toward Air‐Stable and High‐Rate O3 Layered Oxide Cathodes for Na‐Ion Batteries

Advanced Functional Materials, 2022
As one of the fascinating high capacity cathodes, O3‐type layered oxides usually suffer from their intrinsic air sensitivity and sluggish kinetics originating from the spontaneous lattice Na extraction during air exposure and high tetrahedral site energy

Variability of PM2.5 and O3 concentrations and their driving forces over Chinese megacities during 2018-2020.

Journal of Environmental Science, 2023
Recently, air pollution especially fine particulate matters (PM2.5) and ozone (O3) has become a severe issue in China. In this study, we first characterized the temporal trends of PM2.5 and O3 for Beijing, Guangzhou, Shanghai, and Wuhan respectively ...

Impacts of meteorology and precursor emission change on O3 variation in Tianjin, China from 2015 to 2021.

Journal of Environmental Science, 2022
Deterioration of surface ozone (O3) pollution in Northern China over the past few years received much attention. For many cities, it is still under debate whether the trend of surface O3 variation is driven by meteorology or the change in precursors ...

Stability of O3+ N2, O3+ O2 and O3+ CO2 double hydrates: DFT study

Mendeleev Communications, 2019
The possibility of formation of double O3 + N2, O3 + O2, O3 + CO2 hydrates and their structural and energetic properties have been estimated using the DFT calculations in order to expand the hydrate application in ozone storage technology. It was shown that N2 is the most suitable helper gas that could stabilize water framework in the presence of ozone.

O3 photochemistry on O3 episode days and non-O3 episode days in Wuhan, Central China

Atmospheric Environment, 2020
Abstract Simultaneous field measurements of ozone (O3) and its precursors were conducted at an urban site (Zi Yang, ZY) and a suburban site (Huang Pi, HP) in August 2018 in Wuhan, China. The observation results revealed that the mean levels of nitric oxide (NO), nitrogen dioxide (NO2), carbon monoxide (CO) and non-methane hydrocarbons (NMHCs) were ...
